Abstract
In this thesis, I examine three corporate governance related issues, namely, the determinants
of corporate governance (leadership structure, board composition and board size), the
relationship between corporate governance and firm performance (ROA, ROE and Tobin‟s
Q), the impact of six industrial sectors on firm performance (HEALTH, SERVICE, GOODS,
INDUSTRIAL, FINANCE and INDUSTRY), the firm performance between parent and
subsidiaries firms within a group, and the corporate governance culture of firms inside
business groups. This study employed panel data analysis by using fixed-effect estimation of
top 100 listed firms on the HOSE for a period of four years from 2009 to 2012. Empirical
result shows that board size, industrial sectors and business affiliation have positive and
significant impact on firm performance. The two corporate governance mechanisms
leadership structure and board composition are found that they are not to be significantly and
positively related to firm performance in the Vietnam context. For firms with high
performance, investors additionally notice the valuation of firms with larger boards and in
HEALTH or GOODS sectors.
Keywords: Corporate Governance, Firm Performance, Industrial Groups, Business

Chapter One - Introduction
Chapter 1 presents the reasons for forming the subject, the urgency of the research,
then presents research objectives, identify the object and scope of the research as well
as practical significance that study can be achieved, finally announced the
presentation layout of the thesis.
1.1.
Overview:
“The governance of the corporation is now as important to the world economy as the
government of countries.”
–James D. Wolfensohn, President, World Bank Group
For emerging market countries, the enhancement of corporate governance (CG) can
serve a number of important public policy objectives. Corporate governance is
considered to have significant implications for the growth prospects of an economy.
Corporate governance refers to the structures and processes for the direction and
control of companies. It defines the role of the management, board of directors,
controlling shareholders, minority shareholders and other stakeholders. Better CG
may:
•
Enhance market stability
•
Increase investor confidence and trust
•
Lead to transparency of company activities and operations
•
Encourage investment into Vietnamese markets from local and foreign sources
•
Reduce the cost of capital for companies.
However, the way in which corporate governance is organized differs between
countries, depending on their economic, political and social contexts. In Vietnam,
after a decade of economic expansion and the growth of large corporations, corporate
governance has become an important issue for Vietnamese firms as they increasingly
interact with regulators and investors from developed markets. Vietnam‟s CG
Regulations were developed based on the Organization for Economic Co-operation
and Development (OECD) Principles of Corporate Governance. It described current
practice and provided policy recommendations in six areas:
•
Corporate governance framework;
•
Rights of shareholders;
•
Equitable treatment of shareholders;
•
Role of stakeholders in corporate governance;
•
Disclosure and transparency;
•
Responsibilities of the Board.
In Vietnam, the foundation and legislation of corporate governance system are based
on the three adoptions of:
•
The Law on Enterprises in 1999 and its replacement in 2005.
•
The Law on Securities in 2006 and its amendments in 2010.
•
The Competition Law in 2004.
Furthermore, understanding corporate governance standards and issues in Vietnam is
also important to both executives of local companies and foreign multinationals doing
business in this country.
Beside corporate governance issue, business groups are seemed to be playing an
increasingly important role in Vietnam. Large business groups in Vietnam are
characterized by significant ownership concentration. In the recent years, we have
seen a heightened interest in studying the relationship between a firm‟s business
group affiliation and its performance. Business groups are critical in emerging
economies and the ubiquity of business groups suggests that they may affect the
economic performance of group-affiliated members in these economies, either
2
generating benefits for or imposing costs upon members. Yet, in spite of their
important role, there has been no consensus reached, either on the proper way to
define them or on the effects. From an economic theory point of view, business
groups form in order to compensate for market imperfections. However, sociology
tends to regard that reason as too narrow, as they do not take into account social and
cultural factors and do not differentiate between the different types of business
groups.
In Vietnam, lack of empirical evidences, that investigate how business group
affiliation, within firm governance and economic environment affect firm
performance in emerging economies, is an issue for both academics and practitioners.
Vietnam is also absent in international analyses of business group affiliation with
corporate governance and firm performance in emerging markets. In August 2011,
there is a research about the impact of corporate governance on firm performance in
Vietnam, which is measured by obtained survey of corporate governance practices of
100 publicity listed companies on Hanoi Stock Exchange (HNX) and Ho Chi Minh
Stock Exchange (HOSE) conducted in 2009. The result showed that the score of
corporate governance practices is still low with 75% of firms are below middle score
and there is a positive relationship between company market performance and
profitability. Moreover, Dao Thi Thanh Binh and Hoang Thi Huong Giang examined
the relationship of corporate governance and performance in Vietnam commercial
banks sector conducting in August 2012. Based on their suggested models, there was
an insignificant effect of the compositions of the board and the foreign shareholders
on bank performance. This is just two recent typical empirical studies about corporate
governance and firm performance in Vietnam and they do not use external business
variable like group-affiliation firm performance factor to compare the performance
3
within those groups so that we can know which industries in Vietnam have better
performance. Moreover, there is one interesting thing is that we can test the corporate
governance culture between parent companies and subsidiary companies to see if
there is a similar culture about board structure or board composition inside each
groups.
Therefore, it is so important to study the influence of business groups on affiliated
firms‟ performances in Vietnam. Using the unique database, this study will seeks to
understand how business group affiliation, within firm governance and business
industrial environment affect firm performance in emerging economies.
1.2.
Research objective
The purpose of this thesis is to examine the relationship between corporate
governance and group-affiliation firm performance. The objectives are listed below:
Explore the impact of three corporate governance practices (including Board
leadership structure, Board composition and Board size) on firm performance.
Examine whether there is a relationship of corporate governance and firm
performance between parent companies and subsidiary companies in some
business group.
Research question:
What are the relationships between corporate governance practices (consisting
of leadership, composition and size) and performance of listed firms in Ho Chi
Minh Stock Exchange?
Does affiliation with a business group enhance a firm‟s performance and
governance?
Is there a similar culture of corporate governance between parent companies
and subsidiary companies within the given business groups?
4
1.3.
Data and methodology
A highly reliable longitudinal database exists about industries and firms. This
database is four year panel data (from 2009 to 2012) and is based on a sample of top
100 largest firms listed on HOSE. We will examine the effect of group affiliation on
firm performance and corporate governance on firm performance by using ordinary
least square (OLS) regression model.
Moreover, with Eview 6 software, this quantitative research also uses descriptive
statistics and group correlations as analysis tools.
1.4.
Limitation
This study has some limitations. First, through this study, the effect of corporate
governance practices and firm performance is examined by using a sample of top 100
largest companies in the period of four year 2009 - 2012. However, because of limited
sample population and time scale, so this result cannot represent all of companies in
Vietnamese market.
Second, there are still other variables such as board committees, corporate reporting,
board‟s compensation, number of board meeting, gender diversity, education
qualification, director ownership, foreign ownership and dividend policy, etc. which
have potential impact on firm performance. The poor performance of model in
explaining firm performance is caused by the insufficient of some important variables,
which are crucial factors, in the regression model.
In sample of 100 companies, the data is not available for some variables such as board
committees, corporate reporting, average age of directors, and number of board
meeting and so on. This comes from poor corporate governance implementation on
disclosure and transparency in Vietnam.
5
Lastly, another important factors effect to the result of this research is the corporate
governance theories. This research is only applied Agency and Stewardship
perspective theory as the two theory of corporate governance because they are the
most popular and has received maximum attention from academics (Jensen &
Meckling, 1976; Fama & Jensen, 1983) as well as practitioners. However, other
alternative theories of legitimacy theory, resource dependency theory, social contract
theory and stakeholder theory have become prominent over the recent times. In
further development, I will apply those theories to make this research be more
comprehensive and objective.
1.5.
Structure of the study
To achieve the research objectives, the thesis is organized in layout consists of five
chapters. The specific content of each chapter is as follows:
Chapter 1: Introduction presents the reasons for forming the subject, the urgency of
the research, then presents research objectives, identifies the object and scope of the
research as well as practical significance that researchers can achieved, finally there is
an announcement of the presentation layout of the thesis.
Chapter 2: Literature Review will present the basic theoretical concepts related to
the responsibilities of the corporate governance practices and firm performance, and
then summarize and discuss previous research related to the one in this thesis and give
recommendations research model, the research hypothesizes.
Chapter 3: Data and Methodology includes the presentation of the study process,
the definition of the variables studied and the steps to build the scale of the
independent variables, thereby the setting of the research model.
Collection methods and data processing, methods and statistical tools used to analyze
the research data will also be introduced in this chapter.
6
Chapter 4: Empirical Results of the Research particularly includes two parts: the
presentation and the discussion of the results of data analysis included descriptive
statistics, correlation analysis, and multivariate regression analysis to test the research
hypotheses.
Chapter 5: Conclusions, Recommendations and Limitations will be the
conclusions of the research results obtained and make a number of recommendations
for the relationshio between firm performance and governance within the affiliation
with a business group. The final chapter also presents the existence of limitations of
the current study and concludes with a set of recommendations for further research.

Chapter Two - Literature Review
Chapter two provides detailed review of relevant literature. Then the chapter reviews
literature concerning firm-level and group-level corporate governance. Finally, this
chapter presents the conceptual framework and research hypotheses.
2.1.
Theories on corporate governance
Corporate governance is of growing importance, particularly with regards to the
monitoring role of the board of directors. As a result, the theoretical perspectives that
are relevant to this study are based on the governance structures and reporting
practices that affect the value of the firms. This section reviews the theoretical
perspectives of a board‟s accountability that is relevant for this study. It draws on
agency theory and stewardship theory.
2.1.1. Agency theory
Much of the research into corporate governance derives from agency theory which
provides a rational argument for the introduction of corporate governance
mechanisms. The Agency theory is based on the principal-agent framework. Jehnsen
and Meckling (1976) viewed organizations as sets of explicit and implicit contracts
with associated rights. Separation between ownership and control of corporations
characterizes the existence of agency relationship between the board who represent
the shareholders and the management who represent the board and other stakeholders.
Agency theory is concerned with ensuring that managers act in the interest of the
shareholders. In the context of corporations and issues of corporate control, agency
theory views corporate governance mechanisms especially the board of directors, as
being an essential monitoring device to try to ensure that problems that may be
brought about by the principal-agent relationships are minimized (Moldoveanu and
Martin, 2001; Mallin, 2007). The agency role of the directors refers to the governance
8
function of the board of directors in serving the shareholders by ratifying the
decisions made by the managers and monitoring the implementation of those
decisions. Because according to the perspective of agency theory, the primary
responsibility of the board of directors is towards the shareholders to ensure
maximization of shareholder value. The agency problem is how to induce the agent
(managers) to act in the best interests of the principal (shareholders) when the
separation of ownership from management can lead to managers of firms taking
action that may not maximize shareholders wealth. This solution is agency costs, for
example monitoring costs and disciplining the agent to prevent abuse. The important
governance mechanisms used for this purpose are board of directors. The literature on
board, as a governance team, is mainly focused on issues such as board size, inside
versus outside directors (also known as executive versus non-executive directors),
separation of CEO and Chair positions, etc (Dalton et al., 1998; Coles & Hesterly,
2000; Daily et al., 2003) with an aim to improve the effectiveness of oversight.
Various governance mechanisms have been discussed by agency theorists in relation
to protecting the shareholder interests, minimizing agency costs and ensure alignment
of the agent-principal relationship.
2.1.2. Stewardship theory
While Agency theory assumes that principals and agents have divergent interests and
that agents are essentially self-serving and self-centered, stewardship theory presents
a different model of management, where agents (directors and managers) are
essentially trustworthy and good stewards of the resources who will act in the best
interest of the owners (Donaldson 1990; Donaldson & Davis, 1991; Donaldson &
Davis, 1994; Davis et al., 1997).
9
Stewardship theory posits that not only executive managers are intrinsically
trustworthy individuals (Nicholson and Kiel, 2003, p.588) but also directors are
regarded as the stewards of the company assets and are pre-disposed to act in the best
interest of the shareholders (Mallin, 2007). According to Abdulla and Valentine
(2009), stewards are company executives and managers working for the shareholders
so that there is a strong relationship between managers and the success of the firm,
and therefore the stewards protect and maximize shareholder wealth through firm
performance. Moreover, by improved firm performance, the organization satisfies
most groups that have an interest in the organization. Thus, from the stewardship
theory perspective, stewardship theory supports the need to combine the role of the
chairman and CEO and insider-dominated boards are favored by consisting of
specialist inside (executive) directors on the board rather than majority outside (nonexecutive) directors.
2.2.
Previous studies on corporate governance and firm performance
This section discusses the relevant extant theories that attempt to link corporate
governance practices and firm financial performance.
2.2.1. Internationally empirical findings
The literature indicates mixed results regarding combined corporate governance
practices and firm performance. Yermack (1996) examines large US firms from 1984
to 1991 and finds a strong negative effect of board size on Tobin‟s Q. Boards seem
systematically too big. Moreover, this is very costly. Klein (1998), like Hermalin and
Weisbach (1991), investigate the relation between the fractions of board members
who are outsiders and Tobin‟s Q for firms during five different years (mostly in the
1970s). They find no relation between board composition and firm performance
among large US firms in the early 1990s. In addition to that, Agrawal and Knoeber
10
(1996) while conducting a study on US firms found negative relationship between
proportion of outside directors and performance of firms.
Indeed, previous studies in several other countries also find a negative relationship
between board size and firm performance. Bhagat and Black (1999) found no
significant between board independence and firm‟s performance in a long run in case
of US firms. Mak and Yuanto (2002) examine the relationship between the size of the
board and firm performance in Singapore and Malaysia, and find that board size is
negative in relation to Tobin‟s Q.
Although IFC codes recommend that the separation of the role of CEO and chairman
as a sign of good governance, previous empirical analyses do not support it. Weir et
al. (2002) find that duality has no role in enhancing firm performance in U.K firms
and this result is similar with Dalton et al. (1998), Vafeas and Theodorou (1998) and
Brickley et al. (1997). In the context of Hong Kong market, Z. Chen, Cheung,
Stouraitis, & Wong (2005) selected 412 publicly listed Hong Kong firms during
1995–1998 and found a negative relationship between CEO duality and performance
due to managerial entrenchment in companies that combine the positions of CEO and
chairman of the board. This study also show that the composition of the board of
directors (proportion of independent non-executive directors, outsider dominated
board) has little impact on firm performance.
Klein et.al (2005) conducted a study with sample of 263 Canadian firms and explored
that corporate governance does matter in Canada and size was consistently negatively
related to performance.
Also, there is international evidence suggesting this positive link on certain developed
markets. For instance, Selvaggi and Upton (2008) claimed that good CG enhances
firm‟s performance for the United Kingdom and found the presence of a strong
11
causality between the two variables. Similarly, Black (2001) reported the same
conclusions in the case of Russian firms. Besides that, Klapper and Love (2004)
found a high positive association between better governance and operating
performance using firm level data of 14 emerging stock markets with return on assets
as a proxy for operating performance, although affirming that this may vary among
countries.
2.2.2. Empirical findings from Vietnamese perspective
Nguyen Ngoc Thang (2011) examines the effects of corporate governance on firm
performance with a sample of top 100 listed Vietnamese companies in 2009. That
research found that the corporate governance in Vietnam has little impact on firm
performance.
In 2008, Tung Thanh Dao tested the relationship between corporate governance and
firm performance with 20 equitized companies and found that the role of board of
directors has positive impact on firm performance. One more interesting thing in the
result is that there is no relationship between firm size and firm performance.
Dung To Thi (2011) conduct a study with sample top 100 listed companies at the
year-end 2009 and explored that there is no significant relation between board size
and firm performance. Moreover, the dual of CEO and Chairman impacts
significantly on Tobin‟s Q of the companies, but not significant affects ROA.
The following table is to summarize some studies related to the relationship between
corporate governance and firm performance.

Determinants of firm performance and corporate governances and
hypotheses
2.3.1. Dependent variables
Firm performance in the literature is based on the value of the firm. There are many
measures of firm performance. Financial measures of firm performance used in
empirical research on corporate governance fit into both accounting-based measures
and market-based measures (Kiel & Nicholson 2003). Most commonly used
accounting based-measures are return on assets (ROA) (Kiel & Nicholson 2003),
return on equity (ROE) (Baysinger & Butler 1985) and earnings per share. The most
commonly used market-based measures are market to book value ratio and Tobin‟s Q
for reflecting the firm‟s current value and future profitability potential (Barnhart, Marr
& Rosenstein 1994; Ma & Tian, 2009). Besides that, to evaluate performance, some
empirical studies uses return on investment (Boyd,1995; Adjaoud, Zeghal &
Andaleeb, 2007), sales revenue (Bhagat et al.,1999), stock returns (Bhagat et al.,
1999), earnings per share (Adjaoud et al., 2007), net profit margin (Bauer, Guenster &
Otten, 2004) and economic value added (Adjaoud et al., 2007) as a proxy for financial
measurement.
For the purpose of the study, I choose ROA, ROE and Tobin‟s Q as an indicator of
firm performance for both accounting return and market return because this is the
most common variables which are used most in the existing literature on corporate
governance practices (Abdullah 2004; Bhagat & Black 2002; Daily & Dalton 1993a;
Hermalin & Weisbach 1991; Lam & Lee 2008; Yarmack 1996) and reduce the bias.
14
Firm performance in this study is measured in terms of the profitability and value of a
firm.
2.3.2. Independent and controlling variables
The basis of the hypothesis is that the introduction of corporate governance best
practices namely the board leadership structure, board composition, board committees
and corporate reporting practices, will be reflected in firm performance in Vietnam.
The monitoring mechanism of the board leadership structure (Hypothesis 1), board
composition (Hypothesis 2) and board size (Hypothesis 3) is represented to investigate
the boards‟ accountability to shareholders through firm performance. Firm size
(Hypothesis 4) indicates how large the firm is and the returns the firm earns and its
effect on firm performance. Industrial business group (Hypothesis 5) indicates which
industrial sector will have good firm performance in business. Business group
affiliation (Hypothesis 6) shows the relationship how effective of firm performance
between parent and subsidiaries‟ firms inside groups. The corporate governance
culture (Hypothesis 7) indicates the similarity of corporate governance between parent
and their subsidiaries companies within business group.
2.3.2.1.
Board leadership structure and firm performance
The first requirement for each companies in Vietnam to have effective corporate
governance is that the separation of the top two positions of the board (chairman and
CEO). CEO duality arises when the post of CEO and Chairman are managed by one
person. Alternatively, it could also be argued that when one person is in charge of
both tasks, favorable decisions are reached faster provided that person is well aware
of the decisions needed to improve the performance of the firm (Abdullah 2004).
Agency theory evidences that a separate leadership structure could curb agency
problems and enhances the firm value (Fama & Jensen 1983; Rechner & Dalton 1991;
15
Fosberg & Nelson 1999). As such, leadership structure is considered important in
affecting firm performance in this study. To test the above argument in relation to the
Vietnam context the following hypothesis is suggested:
Hypothesis 1: Separate leadership structure is positively associated with firm
performance.
2.3.2.2.
Board composition and firm performance
The board composition is also an important component of the board structure. The
composition of the board in this research refers to the proportion of inside and outside
directors serving on the board. The distinction between the roles of inside and outside
directors is important, because the latter bring in specific advantages and
disadvantages. According to agency theory, these outside non-executive directors are
able to provide superior performance as a result of their independence from firm
management (Dalton et al. 1998). It is believed that increasing the number of
independent directors in the core institutions of governance contributes to the
improvement of corporate performance since it can restrict the power of larger
shareholders and protect the benefit of small ones
Accordingly, proponents of stewardship theory argue that superior performance of the
firm is linked to a majority of insider directors for effective monitoring. Empirical
evidence regarding the relationship between firm performance and board composition
is mixed. According to the arguments put forward by agency theory, non-executive
directors are an important component of the board structure that affects firm
performance. It also means higher proportion of outsiders on the board is significantly
related to various performance measures. On this basis, the second hypothesis in this
study is stated as follows:
16
Hypothesis 2: The number of non-executive directors on the board is positively
associated with firm performance.
2.3.2.3.
Board size and firm performance
Corporate board size is considered to be one of the most important board structure
variables. In the academic literature, “size” variable refers to the number of directors
who serve on the board (Abdullah 2004; Kiel & Nicholson 2003). Large boards are
claimed to be superior to small ones because larger groups have more capabilities and
resources, greater monitoring and advice, and wider external contracting relationships
(Pfeffer, 1972; Klein, 1998; Adam & Mehran, 2003; Anderson, Mansi & Reeb, 2004;
Coles, Daniel & Naveen, 2008). Haleblian and Finkelstein (1993) explained that large
groups could enhance problem solving capabilities, provide more solution strategies
and critical judgment to correct for errors. Moreover, it is acknowledge that board size
is related to firm performance (Kiel & Nicholson 2003). For example, Yermack
(1996) and Coles et al. (2008) found that larger and diversified firms have a greater
number of directors on the board. Boone, Field, Karpoff and Raheja (2007) also found
that as firms become larger and more diversified, board size increased.
As suggested by agency theorist (Jensen 1993), an optimal limit should be around
seven or eight directors and Lipton and Lorsch (1992) suggested the maximum size of
the board should be ten members and it is easier for CEO to dominate. Going by this,
it is hypothesized that:
Hypothesis 3: Board size is positively associated with firm performance.
2.3.2.4.
Firm size and firm performance
Firm size is a control variable used as proxy for measuring the firm performance.
Therefore, we consider firm size as one of the important control variables to be
included in our study. Firm size may be related to corporate governance
17
characteristics and may be correlated with firm performance. Firm size can be
represented by taking the natural logarithm of book values of total assets of the firm.
Size of a firm can have a significant influence on firm performance and a proxy for
firm size is used in almost all studies explaining firm performance.
A firm‟s size is expected to have a positive influence on a firm‟s performance.
Gleason, among others, found that firm size has a positive and significant effect on
firm performance ROA. In contrast, many other researchers such as Mudambi and
Nicosia, (1998), Lauterbach and Vaninsky, (1999), Durand and Coeuderoy, (2001),
and Tzelepis and Skuras, (2004) have found an insignificant effect of firm size on the
firm's performance. Based on this discussion, I propose the Hypothesis 4:
Hypothesis 4: Firm size is positively associated with firm performance.
2.3.2.5.
Industrial business group and firm performance
The relationship between firm performance and governance mechanisms might well
vary from one sector to another. Also, a firm's growth and business cycle varies from
one industry to another (see for instance, Wei, Xie, and Zhang, 2005). For example, it
is also found that a firm's growth and business cycle varies from one industry to
another (see for instance, Wei, Xie, and Zhang, 2005). Therefore, the industries sector
is expected to have an impact on corporate performance. Based on this discussion,
Hypothesis 5 can be stated as:
Hypothesis 5: Industrial sectors affect firm performance.
To control for the effect of industrial sectors on a firm‟s performance, 6 dummy
variables are used. 53 companies are distributed across 6 main industries:
Sector 1 (GOODS): This sector includes companies involved with food
production, packaged goods, clothing, beverages, automobiles and electronics.
18
Sector 2 (HEALTH): The healthcare sector includes hospital management
firms, biotechnology and a variety of medical products firms.
Sector 3 (SERVICE): This sector refers to public service sector including gas,
water supply and electricity firms.
Sector 4 (FINANCE): This sector includes securities, investment funds,
insurance companies and real estate firms.
Sector 5 (MATERIAL): materials sector includes the mining and refining of
metals, chemical producers and forestry products.
Sector 6 (INDUSTRY): This sector includes companies involved with
aerospace and defense, industrial machinery, tools, lumber production,
construction, cement and metal fabrication.
The dummy variable takes the value 1 if the firm is in that sector; otherwise it takes
the value 0.
2.3.2.6.
Business group affiliation and firm performance
Business groups are an important feature of many emerging economies and are
defined as a set of firms doing business in different markets in under common
administrative and financial control. Group affiliation also provides an easier access
to capital, raw materials, and markets for end products of at least some member firms.
Parent company is a company which controls other companies by owning an
influential amount of voting stock or control. Parent companies will typically be
larger firms that exhibit control over one or more small subsidiaries in either the same
industry or other industries. Parent companies can be either hands-on or hands-off
with subsidiaries, depending on the amount of managerial control given to subsidiary
managers. Affiliated companies are companies that is owned and controlled by the
same parent company. Parent company only possesses a minority stake in the
19
ownership of affiliated companies. According to this research, there expects that
parent company and its affiliated companies have also same firm performance. I
propose the following hypothesis:
Hypothesis 6: There is an association between the performance of the parent and its
subsidiary within business group affiliation.
We used an indicator variable to indicate whether a Vietnamese listed company is
affiliated with a particular business group. The indicator variable took a value of 1 if
the listed company is affiliated with a business group, 0 otherwise.
2.3.2.7.
Corporate governance culture
While a focus on within firm governance mechanisms has advanced our
understanding of the links between governance practices and firm performance, there
is an increasing realization that the efficacy of within firm governance may be
dependent on the quality of external governance and institutions (Judge et al., 2008).
It is well documented that many emerging economies, such as China and Vietnam, do
not have well developed external control mechanisms, such as a market for corporate
control, merger, and acquisition laws, and efficient law enforcement.
Consequently, this discussion leads to the following hypothesis:
Hypothesis 7: There is an association between the board characteristics of the parent
and its subsidiary company.
The above hypotheses discuss the effect of corporate governance practices on firm
performance because effective corporate governance is about adhering to best practice
recommendations which suggests that boards should be comprised of a majority of
independent non-executive directors, a separate leadership structure and board size
through appropriate disclosures which will be associated with higher firm
performance. Moreover, there will be hypotheses about the relationship about
20
industrial business group with firm performance or corporate governance culture
inside group affiliation. Here is the Table 2 that summarizes all seven hypotheses
needed to be test:

Chapter Three – Data and Methodology
Chapter 3 explains the methodology used in the study, which includes selection of the
sample and the data collection method. This chapter will also discuss the variables
used to measure, and includes a discussion of the statistical techniques employed to
analyze the data.
3.1.
Data collection
The data employed in this study of corporate governance in Vietnam is covered the
sample period of four years, from 2009 to 2012. The sample consists of top 100
companies with the largest market capitalization listed on the Ho Chi Minh Stock
Exchanges (HOSE). Information on corporate governance mechanisms such as board
size, independent directors, ROE and ROA were hand-collected from the Companies
Annual Reports and financial statements such as HNX 1 , HOSE 2 , cophieu68 3 and
companies‟ websites. The data for this study comes from multiple sources of
secondary data.
3.2.
Methodology
This paper employs the panel data approach as it eliminates unobservable
heterogeneity that different firms in the sample data could present, less collinearity
among the variables and a better measurement than pure cross section or pure time
series data (Gujarati 2003; Baltagi 2001).
In this study, the data will be presented by ratios. Data is analyzed using quantitative
approach. In the quantitative approach, descriptive statistics involve the use of mean,
median, maximum and minimum value to evaluate the selected variables. Other
measures of descriptive estimates like the standard deviation and variance were also

employed so as to see the degree of variability of these estimates. The regression
model is taken the form of the Fixed Effects Model in order to establish the most
appropriate regression with the highest explanatory power that is better suited to the
data set employed in the study i.e. a balanced panel (Greene, 2003; Chen, 2004;
Salawu, 2007). Panel data is developed because of combining time series and cross
sectional data and it is used for the study as it increases efficiency by combining time
series and cross-section data. Panel data involves the pooling observations on a cross
section of units over several time periods. Furthermore, panel data facilitates
identification of effects that cannot be detected using purely cross- section or time
series data. The method of analysis is that of multiple regressions and the method of
estimation is Ordinary Least Squares (OLS). To reveal the relationship between
corporate governance and firm‟s performance, the estimation procedure used by
Kuznetsov and Muravyev (2001) was adopted and modified as: Yit = αi + β1Xit + eit.
Where:
Yit is firm performance (ROE and ROA, Tobin‟s Q,)
αi = refers to time-invariant firm-specific effects
Xit is the independent variables
β1 coefficients
eit is a random disturbance.
i is number of firms.
t is the time period.
By adopting the economic model as in equation above specifically to this study, we
apply to this study to have below models:
PERFt = ßo + ß1 LDSit + ß2 BSIZEit+ ß3 BCOMPit + ß4 SIZEit + eit
Where,
23
PERFit = Firm performance proxies (ROA, ROE and Tobin‟s Q)
LDSit = Separate leadership
BSIZEit = Board size
BCOMPit = Board composition
SIZEit = Firm size
eit is a random disturbance

Chapter Four - Descriptive Statistics and Empirical Result
Chapter 4 discusses the results of the statistical analysis of the data and implications
of the statistical analysis in relation to corporate governance practices, industrial
sectors, business group affiliation and firm performance of listed companies in
Vietnam.
4.1.
Descriptive Statistics for Corporate Governance Variables in Vietnam
As discussed in Chapter 3, descriptive statistics for 2009 to 2012 were calculated for
corporate governance variables and firm performance variables in the study.
Descriptive statistics compared the compliance by the companies with corporate
governance best practice recommendations from 2009 to 2012. They also described
the characteristics of three corporate practices prevalent among listed companies in
Vietnam and the variables used to measure firm performance. A summary of the
descriptive statistics are presented in the Table 4.

4.1.1. Leadership Structure
Analysis of the leadership structure from 2009 to 2012 (Table 4) reports that the
means value of LDS variable is 45% 2009 and it is still 45% in 2010. In 2011, it
decreased to 37% and continued decreasing to 34% in 2012. That means the number
of combining the posts of CEO and the chairman is getting lower from year to year
and number of firms having separated the leadership roles will increase yearly. But
the mean value is greater than 34% in four years indicating that the duality of CEOchairman is quite common in Vietnam. Looking at the Table 4, we clearly see that
there will be 55% of firms having separate leadership in 2009 and 2010; and it
continues to increase to 63% in 2011 and to 64% in 2012. Figure 1 helps us have
better view about how separate leadership structures change in Vietnam over the past
four years. The slope of leadership structure is decreasing yearly. However, over 60%
of the firms in the sample identified the importance of separating the position of
chairman. Examination of the data also shows that some companies have moved back
to separated leadership, whereas some are still keeping combined leadership instead
of choosing separate leadership structures.
27
Figure 1: Mean value of corporate governance practices
4.1.2. Board size
Board size has not varied significantly from 2009 to 2012 with the average size is
nearly 6. The maximum size of board is 11 in three years 2009 to 2012 and increases
to 12 in 2012. Looking at Figure 1, there is a slight slope of changing in mean value
of board size in Vietnam companies and it shows that there is not much changing in
the size of board of directors.
Taking a look at Table 4, the median of number of director is around 6 for four years
means that 40% of Vietnamese companies have number of boards of director in low
range [4-6) and 40% of companies have number of board size in range (6-11]. It
proves that board of director in Vietnam favors the board with not many people. In
Vietnam, Law on Enterprises regulates that number of directors on boards cannot be
less than 3 and more than 11 members (IFC and State Securities Commission
Vietnam, 2006).
28
The lack of universal evidence on “ideal” board size in different markets and nations
could stem from the fact that there is no “one size fits all” in the field of corporate
governance. In addition, empirical analyses suggest a positive relationship with
optimal board size ranging from 5 to 10 members. The range of number of director is
not much with largest board has 11 directors and the smallest one has 2 directors. The
range of this variable seems to conform to Law on Enterprises (LOE) 2005. However,
according to CG Rules and empirical studies, board size of joint stock companies
should be sufficient but not too many members to allow effective operations.
4.1.3. Board composition
Board composition, which is the proportion of non-executive directors on the board of
director, shows that there is a large variation in the percentage of non-executive
directors on the boards in four years (more than 60%). The mean value of proportions
is 62% in 2009 and 2010, and it increased to 65% and 67% in 2011 and 2012
respectively. That means there is a small increasing in the number of independent
directors in top 100 largest listed companies in HOSE. But this change will not make
a high slope because the number is not changing much and Figure 1 is a good
illustration for this change. The proportion of outside directors sitting on the board is
nearly equal to two-third of the board. It means there will be two non-executive
directors if a board of director in company has three members. One can therefore
infers that majority of the boards of the sampled firms are independent. There is
plenty of scope for Vietnamese companies while the Code of Corporate Governance
encourages listed companies to have at least one-third of their board made up in
independent directors4.

4.1.4. ROA
The mean value for ROA was 14.85%, with a minimum of -7.6% and a maximum of
59.8% for 2009. In 2010, the mean decreased to 13.36%, with a minimum of 0.04 and
a maximum of 48.83%. The mean value of ROA keeps decreasing to 11.32% in 2011
and to 9.41% in 2012. Results report that the profitability based on total assets
decreased from 2009 to 2012 and it is described clearly in Figure 2.
Figure 2: Mean value of ROA, ROE, Tobin’s Q and Firm Size
4.1.5. ROE
ROE averaged around 27.52% in 2009 with a minimum value of -12.14% to a
maximum value of 101.55%. The mean value of return on equity decreased in 2010 to
23.85% with a 0.1 minimum value and a maximum value of 77.64%. In 2011 and
2012, the mean value of ROE continues to fall to 18.99% and 15.56% in 2011 and
2012 respectively. Results of descriptive statistics show performance based on
shareholders‟ equity decreased in 2010, 2011 and 2012 and Figure 2 is a good
demonstration for describing this change in mean value.
30
4.1.6. Tobin’s Q
As stated in the previous chapter, Tobin‟s Q measures market performance. A Tobin‟s
Q value of greater than 1 represents a positive investment opportunity. The mean
value for Tobin‟s Q for 2009 was 0.98, with a minimum value of 0.06 and a
maximum value of 8.3. In 2010, Tobin‟s Q averaged at 0.9 with minimum value of
0.09 and maximum value of 8.5. In contrast, the mean value for 2011 was 0.84, with a
minimum value of 0.08 and maximum value of 7.46. Similarly to year 2011, the mean
value is nearly the same with the value of 0.87. The results of Tobin‟s Q value show
that market value of the firm slightly decreased over the years. By taking a look at
Figure 2, the change of Tobin‟s Q is not much in four years so that it looks like a
straight line.
4.1.7. Firm Size
Firm size is represented by natural logarithm of total assets. The descriptive statistics
show that market capitalization of the companies in the sample has not increased
significantly. The mean value of firm size is slightly different because the firm size
averaged at 6.15 in 2009; at 6.27 in 2010; at 6.33 in 2011 and at 6.3 in 2012. The
minimum value and maximum value does not change much from the year 2009 to
2012. The change in mean value of firm size is not much different from the change in
Tobin‟s Q because the slope of changing is very small and we can see it clearly in the
Figure 2. But it is still a good signal because this slope is not going down but it is
going upward over the time.
Descriptive statistics in this study show the extent to which companies in Vietnam
complied with governance structures and corporate reporting practices. The
accounting–based measures of ROE are greater than ROA. The market-based measure
of firm performance, Tobin‟s Q, showed a significant increase during the period under
31
review. Finally, these results indicate that corporate performance measured by all
three ratios increased over the years.
4.2.
Multi – collineartity
When using regression model to test the impact of the leadership structure, board size,
and board composition on firm performance, firstly a correlation test is conducted if
an independent variable is correlated with another independent variable. If there is
correlation between independent, the condition of multi-collinear exists. This can
produce problems in interpreting the coefficients of the variables as several variables
are providing duplicate information. Correlation coefficients express the degree or
strength of the linear relationship between two random variables. The correlation
coefficients among independent variables in the study are presented as follows.
Table 5 presents the correlation matrix. Other than the correlation between ROA and
firm ROE, none of the correlations are high enough to warrant any problem of
multicollinearity.

Note: Firm Size (SIZE = Natural Logarithm of Total Assets), Return on Assets (ROA), Return on
Equity (ROE), Tobin’s Q = Market Capitalization / Total Assets, LDS: Leadership structure, BSIZE:
Board size, BCOMP: Board composition.
The correlation matrix for the variables is presented in Table 5 in order to examine the
correlation that exists among variables. The result shows three issues. First of all,
three measures of firm performance are positively correlated with each other. The
high correlation between ROA and ROE is 85.49%, while the low correlation between
32
ROA and TOBINQ, ROE and TOBINQ is 48.87% and 27.66% respectively. In the
second, the results show that there is a negative relationship between two variables of
corporate governance (board leadership structure and board composition) and three
measures of firm performance i.e. ROA, ROE, and TOBINQ which ranges from
0.05% to 4.67% and 4.53% to 6.54%. On the contrary, there has a positively low
correlation between board size and three measure of firm performance which ranges
from 1.85% to 21.09%. This result means that larger boards are better, therefore the
larger the board, the better the performance of the company.
In the last, the correlation matrix for the variables also examines the correlation
between the explanatory variables. The result shows that there is a negative
relationship between size and three measures of firm performance (ROA, ROE, and
TOBINQ). This implies that larger companies have a lower firm performance.
Besides, size has negative relationship with leadership structure while it has positive
correlation with two residual variables of corporate governance (board size and board
composition).
4.3.
Regression result and discussion
The panel Generalized Least Square (GLS) method was used over the four-year
period (2009-2012). The GLS was adopted because it is a better estimation method
and effectively standardizes the observations (Baltagi, 2001; Greene, 2000). The
regression model includes most variables mentioned above such as the duality of CEO
and chairman, number of directors in board, the board composition, firm size and 6
industrial business groups are used to measure the impact of corporate governance
structures in Vietnam Stock Exchange.
Table 6 reports the first regression result of the impact of CG practice on firm
performance by using random effects GLS estimation, assessing the effect of board
33
characteristics on firm performance. Based on Table 6, I developed three models in a
hierarchical manner. The first model is the measure the effect of independent
variables and business group affiliation on ROA. Model 2 and 3 will exanimate the
relation between corporate governance with industry group and ROE and Tobin‟s Q
respectively.

The value for the R-squared in Table 6, shows that 83.05%, 68.43% and 95.98% of
the variation in the dependent variable are explained by the independent variables of
both the models i.e., with ROA, ROE and Tobin‟s Q respectively. Closer the Adjusted
34
R-squared to 100% the more the variability of dependent variable is being explained
by variation of independent variables. The smaller value of R-square variations in the
dependent variable remains unexplained by the independent variables of the study.
The results obtained above is from the fixed effect models indicate that the overall
coefficient of determination (R-squared) shows that the equation has a good fit with
83.05% for ROA, 68.43% for ROE, and 95.98% for Tobin‟s Q. It means that 83.05%,
68.43% and 95.98% change in the dependent variables (LDS), (BCOMP) and (BSIZE)
are caused by the independent variables (LDS, BCOMP, BSIZE, SIZE, GOODS,
HEALTH, SERVICE, FINANCE and MATERIAL). The higher the R-squared is the
higher the goodness of fit, and the higher the goodness of fit is the higher the
reliability of the model. As the adjusted R-squared tends to purge the influence of the
number of included explanatory variables, the adjusted R-squared of 83.05% for ROA,
68.43% for ROE, and 95.98% for Tobin‟s Q also show that having removed the
influence of the explanatory variables, the model is still of good fit, hence, in terms of
the goodness of fit we can say that the test is fair and those independent components
work in top 100 companies.
The Durbin Watson statistics of 2.14, 2.04 and 1.90 for three firm performance
measures ROA, ROE and Tobin‟s Q respectively; as it is significantly within the
bench mark, we can conclude that there is no auto- correlation or serial correlation in
the model specification.
4.3.1. Leadership Structure
Hypothesis 1 predicted that separate leadership structure is positively associated with
firm performance. In model 1, the setting of positions of the Chairman and CEO and
firm performance efficiency are positive related (β = 0.219532), but this is not
significant effect on ROA because of the high value of probability (p > 0.10).This
35
coefficient remains negative in model 2 and 3 involving interaction terms. But in
model 3, LDS variable is significant with Tobin‟s Q (p < 0.10).
This is inconclusive with our initial expectation supposed a Chairman who is also
possess the CEO position effects negatively on firm performance so that Hypothesis 1
is not supported. Moreover, this result is contrary to the predictions of steward theory
but consider with the agency theory. Despite of their insignificance, these
relationships from three models to some extent have explained that duality of in
corporate governance influences performance efficiency is complex and instable, and
easy impacted by exogenous variables. Due to this fact, the duality in role of CEO and
Chairman usually becomes more active in management process, faster in decisions
making and hence the firm value.
4.3.2. Board composition
Next, continue to examine the relation between Board composition and firm
performance. BCOMP has negative impact on firm performance including ROA,
ROE and Tobin‟s Q with β = -0.007594, with β = -2.483433 and with β = -0.003096
in model 1, 2 and 3 respectively. Looking at model 1, the BCOMP is insignificant
effect on ROA with p > 0.10 but BCOMP is significant with ROE and Tobin‟s Q
because the value of p < 0.10. The implication of this is that for the 100 sampled
firms, there is no relationship between the firms‟ financial performances and the
outside directors sitting on the board. It is also pointed out that the more outsider of
board of directors, the greater the loss of firm value. Because hypothesis 2 predicted
that board composition leadership structure is positively associated with firm
performance so that we reject hypothesis 2.
36
4.3.3. Board size
Hypothesis 3 predicted that board size has positive impact on firm performance. From
the regression results in model 1, 2 and 3, the result shows that the role of the board
size of directors has a positive impact on the three firm performance measures. In
addition, the coefficients for the significant variables are also found to be small with β
= 0.17, 0.22 and 0.01 for ROA, ROE and Tobin‟s Q respectively. However, in model
1, the impact of BSIZE is insignificant as probability coefficient is 0.15 (p greater
than 0.10). But the effect of BSIZE is significant with ROE and Tobin‟s Q because
both of the values of p in model 2 and 3 are less than 0.10. Therefore, the Board size
affects positively ROE and Tobin‟s Q and does not affect ROA in Vietnam. In fact,
there are also a set of studies which are relevant to the investigation between board
size and corporate performance. The result of this positive relationship in Vietnamese
firms is also consistent with a number of empirical studies in the world. According to
the estimated effects, increase of the Board size improves company performance. The
result shows that the role of the board of directors has a positive impact on company
performance and Hypothesis 3 is accepted.
4.3.4. Firm size
Firm size turns out to be related to firm performance because all the statistically
significant results for size in model 1, 2 and 3 show that size has a negative and
significant effect on the three firm performance measures ROA, ROE, Tobin‟s Q. The
SIZE control variable has negative and significant coefficients (with β = -1.08 and p <
0.10 in model 1; β = -1.41 and p < 0.10 in model 2; β = -0.40 and p < 0.10 in model 3)
at conventional level, so that firm size turns out to be negatively related to ROA, ROE
and Tobin‟s Q. Suggesting that larger firms tend to be less efficient, everything else
equal. There is a higher probability that the company will have a negative financial
37
result with larger size. Increasing of the size of company (SIZE) is associated with a
decrease in the probability of corporate “success”. This result argues that the effect of
the company size strongly affects firm performance, i.e. this effect can be considered
as important.
However, it is also not consistent with the conventional wisdom that larger firms are
better diversified and they can thus hold less capital to buffer against losses. It can be
said that the significance of firm size indicates that large firms do not earn higher
returns compared to smaller firms, presumably as a result of diversification of
investment and economies of scale. This result is not consistent with previous
findings including Gleason et al. (2000), among others. According to the above result,
I reject the hypothesis 4: The firm size is expected to have a positive influence on a
firm capital structure.
4.3.5. Industrial business group
This finding is similar to the result suggested by Coles, McWilliams and Sen (2001)
that industry performance is significantly related to company performance in addition
to CG variables. Industrial group variable is considered to be important factors effect
to the firm performance.
In Table 6, only 5 industrial sectors are presented and 1 sector is dropped out because
all 6 industrial business groups are dummy variable so that we cannot add all of them
in one regression model to avoid multicollinearity issues. Hence, the available
industrial variables will be GOODS, HEALTH, SERVICE, FINANCE and
MATERIAL. The one disappearing in the regression equation is INDUSTRY sector.
Based on the regression results, firms fall into two groups which are dependent on the
corporate governance significant value: 3 sectors GOODS, HEALTH and
MATERIAL will be in group 1 and the remaining 2 sectors SERVICE and FINANCE
38
are in the same group 2. The only different thing between group 1 and 2 is that the
significant value because group 1 has a significant impact but group 2 has
insignificant relationship so that group 1 affects the firm performance and group 2 is
not. We clearly see that all sectors in group 1 are positive impact on firm performance
because the probability is less than 0.10 but the HEALTH has negative impact on
ROE. It should be noted that MATERIAL sector only has positive and significant
relationship with Tobin‟s Q (not with ROA and ROE). The positive and significant
impacts of these industrial dummy variables in group 1 indicate that a higher level of
investment in these sectors could be associated with a higher ratio of ROA, ROE and
Tobin‟s Q. It also shows that the GOODS, HEALTH and MATERIAL sectors is
profitable, and the Vietnamese economy depends to some extend on GOODS,
HEALTH and MATERIAL as a source of income. The coefficients are positive or
negative; depending on the relative performance between the industries, investing in
these sectors may be profitable.
In the recent years, the economy and society of Vietnam has attained more important
achievement. The human life has greatly improved and enhanced. Especially, the
HEALTH industry has a good performance in the fields of prevention of disease,
medical examination and cure. In general, the health industry has achieved many
targets such as the age, nutritional standard, health, etc. All the above reasons are
explained clearly for development and positive performance of HEALTH industry in
the Table 6.
Per capita income of Vietnam is more and more improved. It boosts development of
the goods industry which is the solid growth resource regardless of economic crisis in
the world. In 2012, AC Nielsen has ranked Vietnam is the country which has the
fastest speed of growth in the field of goods in the Asian (Vietnam 23%, India 18%,
39
and China 13). Vietnam has 3rd population in the ASEAN. About 70% of population
is in the labor age (15 to 60 years). Therefore, consumer needs are continuously
expected and extended in next 30 years. All of them are reasons for good performance
in goods industry and that is the reason why GOODS sector has positive impact on
firm performance.
The reason for the insignificant of group 2 because the significant level is greater than
0.10 that the reason why SERVICE and FINANCE are not related to firm
performance. The negative sign for some industries could be as a result of the
negative equity value for some firms included in the analysis as a result of distress.
Hence, three sectors in group 1 showed a better level of performance than two sectors
in group 2. Through the Table 6, we conclude that each industry sector has different
effect on firm performance.
The hypothesis 5 state that industrial business group has positive associated with firm
performance. So that hypothesis 5 is accepted.
4.3.6. Business group affiliation and firm performance
Hypothesis 6 stated that parent companies and their subsidiaries are positively
associated with firm performance. In this part, the relation between two variables for
the proxy of business group affiliation and firm performance will be considered. By
using four OLS models to make the comparison of the firm performance within
business groups. The models will be ROA_MO to ROA_SON and ROE_MO to
ROE_SON. In addition to make the result to me more consistent, two corporate
governance practices of subsidiary companies (such as: board size (BSIZE_SON) and
composition of boards of subsidiaries (BCOMP_SON)) will be counted in the
regression equation. The joint examination of various corporate governance issues
40
and firm performance will be critical for further scrutiny of the firm performance of
group-affiliated companies.

From the result in Table 7, the firm performance of parent companies are positively
associated subsidiary companies. Let‟s consider the first comparison between ROA of
parent companies to ROA of subsidiary companies. It is found that ROA_MO is
significant (p < 0.10) and positive impact on both ROA_SON because the values of β
will be 0.3. Moreover, the ROE_MO impacts significantly and positively with firm
performance of subsidiaries (with β = 0.97; p < 0.10 for second equation). The Rsquared which ranges from 0.82 to 0.71 is satisfactory in all cases of two measures of
firm performance. This indicates that about 71% to 82% of the variation in the firm
performance measure ROA and ROE of affiliated companies has been explained by
the variation in firm performance measure ROA and ROE of parent companies. Table
7 shows the firm performance between parent company and their subsidiaries within a
business group will be similar and related to each other. When the operation process
of parent company is good and generates better firm performance, then the firm value
41
of subsidiary companies will be more efficient too. As stated before in chapter 2,
hypothesis 6 is not rejected.

Analysis of variance was also performed to find the similarity of corporate
governance between parent companies and their subsidiary companies (Table 8).
Results did not show significant relationship in comparing between BSIZE_SON and
BSIZE_MO because the value of probability is high (p = 0.29) and greater than 0.10.
But the effect of BCOMP_MO to BCOMP_MO is significant (p = 0 < 0.10) but it has
negative relationship because the value of β is a negative number (β = -0.5).
Therefore, it is no evidence showing that there is a relationship of corporate
governance structure between parent companies and their subsidiaries within business
group affiliation. In summary, the hypothesis 7 was rejected.

This study has done an analysis on the corporate governance mechanisms to see their
influence on firm performance. Furthermore, there will be comparisons between
industrial business group, firm size, business group affiliation and firm performance.
The impact of corporate governance culture within group is also tested with this
research. Indeed, the study uses Tobin‟s Q, ROA and ROE as performance measures
to evaluate the firm performance and the results are tabulated in Table 6, Table 7 and
Table 8 respectively. The study finds that there are two negative impact of leadership
structure and board composition on firm performance. Board size is the only one of
three corporate governance mechanisms that has positive effect on performance. By
looking on industrial sectors and business group affiliation, both groups have a
significance and positive relationship on ROA, ROE and Tobin‟ Q. In contrast, the
last two variables are firm size and corporate governance culture have negative impact
so that their hypothesis is not supported. Table 9 will summarize our main results of
descriptive statistic to let us have better view about this research.

Chapter Five – Conclusions and Recommendations
There is no doubt that several studies have been conducted so far (and is still on –
going) on the examination of the relationship between corporate governance
mechanisms and firm performance measures, but the outcomes of these studies are
mixed.
This research examines the relationship between the CG practices and performance of
Vietnam‟s listed companies, using three CG practices (duality, board composition and
size) and three firm performance proxies (ROA, ROE and Tobin‟s Q). The two
variables: industrial group performance and CG culture within business group are also
tested in this paper. All the analyses are based on the data of top 100 largest
companies which are listed on HOSE from 2009 to 2010 for empirical test. Panel data
methodology is employed; the method of analysis is multiple regressions and the
method of estimation is OLS.
The results show CG practice has little impact on the performance of Vietnam‟s
companies and suggests that CG practice could not explain the whole company
performance. The study reveals the following results:
i.
There is a negative and significant relationship between the integration of
manager and the chairman of the board and Tobin‟s Q and they are not
consistent with the hypotheses, inferring that, under the condition that CEOs
serve as executives, the board would likely fail to be an objective supervisor,
correspondingly putting firms at a disadvantage. Therefore, it can be also
concluded that higher profitability for firms in Vietnam is due to the
separation of the position of CEO and chairman. This evidence is also
supported by Jensen (1986) who suggests that it gives too much power to
someone holding two top positions and thereby allows decisions to be based
44
on their personal interest with a consequent drop in firm performance. Based
on the agency theory, the separation of manage and chairman not only can
help the enterprise avoid a severe crisis, but also make the chairman of the
board valuate the manager more objectively. Hence, it is better to separate the
two roles in order to make sure that the top leadership of the firms have a
proper check and balance as suggested by the agency theory. However, in
contrast, this study also found that there is no significant relation between firm
performances as measured by ROA and ROE across the board leadership
structure as separate and combined leadership in listed firms in Vietnam.
Tobin‟s Q measures the market value while ROA and ROE measure
accounting profitability. It appears that the market prefer a firm without dual
chairman-CEO than that with dual chairman-CEO even though the accounting
performance. It implies that there is no significant impact on firm value or
decision making when someone holds both the CEO and chairman position.
ii.
There is a negative and significant relationship between board composition
and firm performance. It implies that firm performance is decreased as outside
directors are added to the board. This result suggests that the more
independent the board is, the more detrimental firm performance would be.
Contrary to claims in the hypothesis, increasing of board independence should
be noted with caution the negative relation between board independence and
future operating performance. Perhaps, the need for decreasing outside
directors when the commitments of inside directors, who know the company
very well, will benefit the firm. Based on the recommendation of OECD and
ACGA for reducing outside directors, the minimum proportion between
outsiders and insiders must be at least one-third of a board.
45
iii.
There is a positive and significant premium effect between board size and firm
performance. BSIZE is only one of three CG practices is significantly
positively correlated with performance and means that larger and diversified
firms have a greater number of directors on the board. Moreover, it is
implying that, in a large size board, the diversity of directors‟ opinion has a
positive impact on making decisions. It is quite understandable that BS has a
certain positive relationship with firm performance represented by ROA, ROE
and Tobin‟s Q. There are a number of possible advantages associated with a
larger board such as an enlarged provision of valuable advice and networks. A
larger board could also favor better decisions since it is likely to be based on
diversified competencies and experiences. The mean value of BSIZE is around
6 in four years so that the size is fitted with the recommendation size for
Vietnam companies from IFC and State Securities Commission Vietnam,
2006. To maximize the profits, firms should be “efficiently” sized in range
from 5 to 10 members in a board.
iv.
The size of the firm is shown to have effect on the firm performance and firm
size is negatively related to company performance, which suggests that firms
with greater size tend to be less efficient on firm performance. Size of the
firms in all the three models in Table 6 is remained negative to ROA, ROE
and Tobin‟s Q so that firm size is not considered as the function of firm
investment opportunity in this case. The negative sign shows that, on average,
profitability of Vietnamese companies decrease with a company size.
It is also not consistent with the conventional wisdom that larger firms are
better diversified and they can thus hold less capital to buffer against losses. It
can be said that the significance of firm size indicates that large firms earn
46
higher returns compared to smaller firms, presumably as a result of
diversification of investment and economies of scale. This may be because
companies may not be able to fully control and monitor the business as the
companies become larger in size. Thus, the performance slowly decreases.
This result is not consistent with previous findings including Gleason et al.
(2000), among others because they found that firm size has a positive and
significant impact on firm performance ROA, and Tobin‟s Q, indicating that a
firm‟s size is an important determinant of corporate performance.
v.
We find that the positive association and significant impact of three industrial
sectors (GOODS, HEALTH and MATERIAL) on firm value measurements
(ROA, ROE and Tobin‟s Q). Specially, firms in GOODS and HEALTH
sectors have higher efficiency because health industry has achieved many
achievements and Vietnam has 3rd population in the ASEAN, together with
more than 70% of population is in the labor age. The negative and significant
coefficient of HEALTH variable could be as the result of the negative ROE
value for some firms. It also means that natural resource companies in
Vietnam less use leverage as source of expanding.
vi.
Meanwhile, it is also found that there is a positive and significant relationship
of firm performance between many firms within groups. Hence, it showed that
if parent companies have good firm performance, the performance of
subsidiaries firms will increase too. It is easy to understand that because the
profits of business group affiliates were higher than otherwise comparable
unaffiliated firms. Moreover, group affiliation also provides an easier access to
capital, raw materials, and markets for end products of at least some member
firms. Besides that, groups generally enjoy a good reputation, and are able to
47
derive benefits through their connections with the government and help the
affiliated firms in achieving sustained superior performance, which are not
easily available to stand alone firms. Because of these benefits, group
affiliation has potential benefits by playing substitution role to fill the
institutional voids such as lack of intermediaries in product, labor and capital
market. The above analysis points to the various benefits of being a business
group member and help us understand the benefits and costs of business group
affiliation in emerging economies, especially in Vietnamese market.
vii.
There is a negative and significant relationship impacts on board composition
between parent companies and subsidiaries within groups‟ governncance. One
can infer that the negative governance effect of outside directors proves that
the governance culture between parent and subsidiaries firm inside groups is
not similar and correlated to each other. Or we can infer that when parent
companies increase the board independence, there will be a reduction the
outsider in board of subsidiaries and this is contrary to the stated hypothesis
above. Moreover, the size of boards inside each company within a group has
positive impact but insignificant relationship. Notably, the study finds that
listed firms within a group will not have same the same model or structure of
CG in the context of Vietnam.
In general, all the values for the R-squared in this research are high and greater than
61.17% which endorses that more than 61.17% of the variation in the dependent
variable is explained by the independent variables of the model. Less than 38.83%
variation in the dependent variable remains unexplained by the independent variables
of the study.
48
The contribution of this paper is that it extends the research streams from both firms
levels and business group levels to examine how effective in firm performance and
similar of corporate governance mechanisms between parent and subsidiaries firms
within business group in Vietnam. The above findings have important implications for
researchers, senior policy makers, and corporate boards: It is plausible that
governance factors are not much related to firm value.
Based on IFC and the State Securities Commission (SSC) published the Corporate
Governance Scorecard Report 2012, the report remarks the current regulations on
corporate governance in Vietnam are often insufficiently implemented. The report
suggested businesses should further raise their awareness of the importance of good
governance practices. In particular, they should focus more on protecting the interests
of shareholders and related parties, promote disclosure and ensure responsibility of
the board of directors in risk management.
Corporate governance is a competitive advantage of a business, said Simon Andrews,
IFC regional director for Cambodia, Laos, Myanmar, Thailand and Vietnam. He said
applying international standards on corporate governance and ensuring accountability
and transparency in decision-making will help businesses improve their appeal and
cut costs for capital access. This will provide them with an important advantage at a
time when the economy has a lot of fierce competition, he added.
In summary, the regression analysis finds that there is some and not consistent
relationship between current quality of CG practice and the financial measures. We
found that better corporate governance mechanism is associated with higher corporate
performance. Interestingly enough, six industrial sectors performance is found to be
consistently significantly or insignificantly and positively correlated with company
performance. This result means that CG practice only have a small impact on
49
performance of companies. Instead, industry performance is of stronger influence on
the performance of Vietnam‟s listed companies.
