CHAPTER 1 INTRODUCTION1.1 Research motivation andcontext

It could be said that today’s world has faced increasing threats of the poly-crisis such as the disruption of the global supply chain, soaring energy prices and inflation rates, and geopolitical risk (Lu & Luong, 2022; Phan et al., 2022b; Yusoff et al., 2019) This prospect underscores that most organizations have to find effective ways to sustain their buoyant markets In this case, tapping into knowledge-based resources can be seen as an essential preparedness to open new roads for modern companies because it assists an organization in achieving competitive advantage and stable development (Alvino et al., 2020; Suciu & Năsulea, 2019) This assertion is also true in the banking industry, which usually depends much on intellectual resources rather than physical capital to provide suitable products and services to fulfill the changing needs of their customers and succeed in competitiveness (Adesina, 2019) To some extent, intellectual capital (IC) may be an effective signal to evaluate the degree of banks’ performance compared with their rivals (Meles et al., 2016; Stewert, 1999).

Unsurprisingly, scholars and regulators have recently paid much attention to implementingICinbankingoperations.Whilethenumberofstudiesinthisfieldhasfocused mainly on the correlation between IC and banks' productivity (e.g., Alhassan & Asare,2016; Yalama, 2013; and among others), IC and one’s profitability (e.g., Le & Nguyen, 2020; Poh et al., 2018; and among others), IC and ones’ risks (e.g., Dalwai et al., 2021; Nguyen et al., 2021; and among others), or technical, allocative and cost efficiencies (e.g., Adesina, 2019; Le et al., 2022), the aspect of financial intermediation in the banking system as well as the link between IC and one of the most critical aspects in banking operations, namely totalnon- interest incomes, seem to remain an undiscoveredarea.

With that in mind, this research is to tackle the key issue of whether the implementation of IC has fostered the financial intermediation and total non-interest incomes in the banking system or not In this sense, Vietnam may provide one of the ideal countries for finding a clear answer and filling this vital gap in the literature for the following reasons.

Vietnam's economic growth has witnessed a fast pace in the ASEAN region, and it is hoped that this country will be the next tiger in Asia (Le, 2021; Le & Nguyen, 2020).

According to the statistics from World Bank Data, from 2006 to 2019, the GDP growth of Vietnam nearly stood at an average of around 6.5% before dropping to about 2.9% in 2020 due to the adverse consequences of COVID-19 Notwithstanding, since the financial market seems to remain undeveloped, sustainable economic growth and development have relied mainly on the effective operations of the banking system, which is also deemed as the backbone of the Vietnamese economy (e.g., Le et al., 2022; Le & Nguyen, 2020; Phan et al., 2022b).

The statistics revealed by World Bank Data illustrate that the economic indicators of domestic credit over the private sphere supported by banks jumped from about 65% to over 116% during the 2006-2020 period This remarkable escalation means that the development of the banking sector plays an imperative role in ensuring and fostering the growth of the Vietnamese economy Therefore, growing financial intermediation activities have become one of the significant factors in ensuring sufficient economic resources and sustaining the developing economy Additionally, the Vietnamese banking market may become fiercely competitive, resulting from the appearance of foreign banks, followed by participating in the World Trade Organization in 2007 (Huynh & Dang, 2021; Le & Nguyen, 2020; Phan et al., 2022a).

regard, digging more into intellectual resources may be an underlying business strategy to thrive in their business activities Indeed, it is witnessing an increasing evolution from the traditional paradigm of strategy to the knowledge-based paradigm, which deems IC as the driving force of sustainable value creation and sustainable competitive advantage (Alvino et al., 2020; Khan et al., 2019; Marr & Roos, 2012) In this case, the business strategy construction of Vietnamese banks is not the exception, and hence, managers and decision- makers in domestic banks cannot ignore IC perspective in both building their business strategy and managing businessoperations Ontheotherhand,asGreenbaumetal.(2019)implied,bankstraditionallyactasfinancial producers and servicers; they are regularly forced to provide up-to-date products to satisfy their customers' demands, by which they can flourish in today's economic climate Such this scenario underlines the primary driver of

requirements.Inshort,discoveringthelinkbetweenICandfinancialintermediationinth e

banking industry would be a requisite study for not only the Vietnamese banking sector but

In addition, the dissertation opts for non-interest incomes as the key objective to explore the effect of IC on the business operations of banks for some main reasons First and foremost, the transformation from traditional incomes into non-interest incomes, including commissions, fees, and trading incomes, is seen as one of the essential strategies driving the operations of banks in the modern economy these days (Bian et al., 2015) Indeed, the shift towards non-traditional sources of income could bring certain benefits for banks, from reducing risk and funding costs (Tran, 2020) to enhancing profitability (Mostak Ahamed, 2017).

At the same time, such this orientation has required banks to possess necessary capabilities of technology, expertise, and human resource (Mostak Ahamed, 2017) In this vein,theemergenceofICwouldbecomethebridgetofillthesepreconditions.Inaddition,to deal with the aftermath of the global financial crisis, operations of the banking industry in particular and the financial system, in general, have been constrained by tighter regulations becausesuchfinancialderegulationmayencouragebankstojoinmorecasino-stylegambling, leading to growing instability (Tran, 2020) Hence, banks have to navigate their business strategiesbeyondtraditionalactivitiestoachievehigherprofitability.Thissituationhighlights the vital role of both IC and non-interest incomes in banks; thus, discovering the correlation between these factors would provide a major insight into banking operations, especially in emerging markets where the banking system is considered the backbone of theeconomy.

Taken together, it is hoped that the dissertation, namely“Business strategy,

bankoperation, and the role of intellectual capital development”will may shed more light on

the role of IC in both financial intermediation and non-interest income activities and provide valuable helpfulness for not only academicians but also policy-makers in the banking sector.

1.2 Main purposes of thedissertation1.2.1 Generalpurposes

In general, the dissertation is to conduct an empirical investigation into the role of intellectual capital in financial intermediation and non-interest income activities of

Vietnamesedomesticbanks.Inthisregard,thestudywillpointoutthetheoreticalbackground to advocate these main concerns before performing an empirical analysis By leaning on the findings, the dissertation is also expected to provide useful implications for managers and decision-makers of Vietnamesebanks.

1.2.2 Specificpurposes

In particular, the major purposes of the current study are to focus mainly on some key aspects as follows:

First, one of the scientific endeavors of the dissertation is to construct the theoretical foundation that demystifies the pivotal role of IC in business operations as well as strategies of banks.

Next, the present study aims to determine the association between IC efficiency and financial intermediation activities as well as IC efficiency and non-interest incomes basedon the context of the Vietnamese bankingindustry.

Moreover, other effort of the writer is to explore the extent to which the different components of IC exert both financial intermediation activities and non-interest incomes of the Vietnamese commercial banks.

Eventually, by leaning on the empirical findings, the present research endeavored to propound some major implications under both theoretical and practical views for not only academicians but also policy-makers as well as banking leaders.

In other words, as stated early, the current dissertation carried out is to answer the following straightforward questions of:

income activities of Vietnamese domestic banks ornot?

In addition, the transformation from traditional incomes such as lending interests into non-traditional incomes may become one of crucial business strategies of banks against the backdrop of increasingly competitive market resulting from the emergence of foreign banks, rapid changes in technological innovation, tightening regulations, and so on Therefore, the

The period is chosen because it has witnessed many changes in the banking system in Vietnam, including regulations, structures, the emergence of foreign banks, and technology-based orientations (e.g., Huynh & Dang, 2021; Le & Nguyen, 2020; Phan et al., 2022a; Phan et al., 2022b; Tran, 2022) At the same time, many prominent events have emerged during the same period in the Vietnamese economy (see the detailed analysis in Chapter 3) Thus, to some extent, the findings would draw the general picture of the

At the same time, the dissertation utilizes the prior findings of previous authors in the existing literature to calculate the main explanatory variables including IC efficiency and its ingredientsaswellastobuildtheempiricalmodels.Accordingly,toestimatetheICefficiency of domestic banks, following many extant studies (for example: Adesina, 2019; Le et al., 2022; Nguyen et al., 2021; Ozkan et al., 2017; Poh et al., 2018, and among others), the study employs VAIC model (the value-added

Furthermore, the dissertation also controls a variety of variables including bank-specific characteristics and macroeconomic conditions Adding these variables into the analysis model may give a deeper insight into the research findings and, to some extent,they can play a part role in reexamining the results These variables consist of bank size, capital ratio, loan loss reserve ratio, income ratio, GDP growth ratio, and inflation ratio, which have been used by many financial studies in the recent years (e.g., Adesina, 2019; Le & Nguyen, 2020; Nazir et al., 2021; Tran et al., 2021; and amongothers).

Besides, regarding the first dependent variable, financial intermediation in banks, although there are certain debates on measuring financial intermediation, the ratio of total loanstototaldepositsisstillpopularinthebankingliterature(Boďa&Zimková,2021).Some existing views scrutinize that macroprudential policies should be built around this

incomes in the banking sector.

ii) Moreover, most studies in this area mainly take the context of the industrialized countries to perform, notably US and China which are considered the most influential economies globally (Alvino et al., 2020) Hence, by conducting an investigation in Vietnam, which has been seen as a pivotal part of the Southeast Asia region and the Asia region as a whole, the study will bring more profound insight into the driver of IC in rebuilding business strategies of domestic banks to not only economists but also decision-makers in developingeconomies.

iii) In addition, as the research conducted by Poh et al (2018) indicated, different results when investigating the impact of IC in the banking industry may come from various measures of banking performance and periods chosen By selecting financial intermediation activities and non-interest incomes as the main research objectives along with the period covering from 2006 to 2020, the author would dig more intothe impactofIConvariousdimensionsofbusinessoperationsinbanks,andtherefore,the

CHAPTER 2 THEORETICAL BACKGROUND ANDLITERATURE REVIEW

2.1 Concepts of intellectualcapital

In today's world, economists tend to have a general consensus on the central role of intellectual capital in supporting organizations to gain competitiveness and achieve sustainable growth, especially against the backdrop of a fiercely competitive business environment, rapid changes in technological innovations, and global challenges (e.g., Khan et al., 2019; Kweh et al., 2022; Suciu & Năsulea, 2019; Vătămănescu et al., 2019) In the early stage, the definition of IC has been paid special attention by many economists worldwide According to Khalique et al (2013), the first interpretation is produced by Jon Kenneth Galbraith in 1969 However, Harris (2000) suggests that Schultz was the first economist who introduced the clarification of IC and the economic values of IC in 1963.

Even though there are certain debates about the definitions, classifications of IC, and the measures of IC in the existing literature, it is widely recognized that in the knowledge-based era, IC is deemed as the indispensable ingredient in the business strategies of any organization Indeed, although there are certain differences between researchers in interpreting IC in literature, in general, IC is seen as one of the intangible assets to fuel the operations of companies (Ghosh & Mondal, 2009; Mondal & Ghosh, 2012), as one of the mainresourcestoenhancecompetitiveadvantage,firmvalue,theconfidenceofstakeholders, and sustain economic growth (Caputo et al., 2016; Jardon & Martínez-Cobas, 2019), as one of the reliable sources to ensure prosperity and well-being of individuals, corporations, and countries (Alvino et al., 2020; Suciu and Năsulea,2019).

At the same time, IC has regularly included three main components: human capital, structural capital, and relational capital (Adesina, 2019; Le & Nguyen, 2020; Meles et al., 2016; Ozkan et al., 2017; Poh et al., 2018) Accordingly, the interpretation of human capital usually involves the competence of people in an organization, such as skills, experiences, knowledge, and so on Meanwhile, the definition of structural capital is related to a firm’s fabric, business strategies, policies, and so on By contrast, the last component, relation capital, also named capital employed, closely involves extrinsic factors, including clients, suppliers, and relevant stakeholders.

Figure 2.1 below presents the heart role of value creation that is blended from three classifications including human capital, structural capital, and relational capital together Besides, Table 2.1 illustrates a variety of definitions related to intellectual capital and its components in the existing literature.

Source: Based on the prior studies conducted by Edvinsson & Malone (1997);Harris,(2000); Stewart & Ruckdeschel(1998)

Figure 2.1 The illustration of the value-added creation springing from the three mainingredients of IC

As Figure 2.1 illustrates, the value creation is of the interested concern of enterprises, being the blended and integrated relationships and close connections between three major intangible assets: human capital, relational capital, and structural capital In this light, the more interconnected between these elements, the more maximized value space (Pew Tan et al., 2008) According to Edvinsson & Malone (1997), the firm value only results from the

Table 2.1 Some definitions of IC and its components

Intellectual capital obtains valuable substances suchasexperiences, knowledge, IP (intellectual property), and information A company could harness these valuable materials to build wealth andpropensity.

Intellectual capital has been knowledge that, in turn, could be transformed into the profitability of an organization Intellectual capital can be seen as a new resource which assist firms in reaching new achievements on businesspath.Intellectual capital has been the discrepancy betweenacompany's market and book values At the sametime,intellectual capital is the resource that will assist acompany to sustain competitiveadvantages.

Intellectual capital is depicted as intangible or non-physical assets that a company can gain value and advantageous competition from these resources.

Intellectual capital is seen as an invisible activityconsisting of the capability of individuals in learning, namelythehuman capital, an organizational culture known as the structured capital, and the interactions with extrinsicfactors named the relationcapital.

Intellectual capital is defined as the total of all knowledge that an organization can harness effectively in performing business operations to value-added creation.

Intellectual capital is one of the important sources that may enhance the competitiveness of a company and the

confidence of multi-stakeholders.

Human capital is the distinctive characteristic that individuals or/and teams possess, and it is deemed as intangible assets of an organization By tapping intothisf a c t o r , a n y c o m p a n y c o u l d g a i n a d v a n t a g e s o f

Structural capital is something owned by a company in general Specifically, it is related to data, patents, policy, invention, strategy, and technology From this author's perspective, structure capital is the backbone of IC that would ensure the smoothness of knowledge transmission within a company.

Structural capital would be held in companies even when their staff leave home.

Structural capital is being controlled by companies, consisting of information technology, culture, innovation, optimized process, and relevant explicit knowledge.

Relational capital is identified as the value stemming from individuals and organizations that have relations witha companyinsellingandbuying.Inotherwords,thisfactoris

usually related to multi-stakeholders such as customers, suppliers, and other relevant stakeholders.

Relational capital, also named capital employed, can be defined as the connection between companies and their multiple stake-holders.

Cabello-Medinaet al (2011)

Relational capital is considered the sum of resources (both extant and potential), springing from the relational networks of individuals and organizations as a whole.

Relational capital is the combined relationships withtheexternal world that would comprise clients,f i n a n c i a l

institutions, stakeholders, and other agents.

Structural capital is the factor that emphasizes intrinsic knowledge such as policy, strategy, and structure of a company.

Relational capital is the factor related to a firm's extrinsic relationships, such as clients and stakeholders.

Inshort,itisanundeniablefactthatoperatinginthetechnology-ledandknowledge-based era, most organizations cannot neglect the role of intellectual resources in constructing businessstrategies,especiallywhenthecompetitivenesshasbeensouringandtheuncertainty has become more unpredictable This argument is reflected in the scientific endeavors of scholars to codify the role of IC throughout the existingliterature.

Indeed,basedontheexistingdefinitionsintheliteratureandtothelimitedabilitiesofthe author, it can be concluded that there are the great efforts to identify the concept of IC, however having certain differences in interpreting IC’s definition as well as its elements,

dependingonthedifferentdisciplinesandvariousangles,suchasfinanceandaccounti ng,

economics and strategies, marketing and communication, and so on (Le et al., 2022; Le & Nguyen, 2020) Furthermore, reaching a whole consensus on IC’s interpretation tends to be theinconclusivedebateintheextantliterature(Bayraktarogluetal.,2019;Naziretal.,2021).

Similarly, the definitions of IC’s elements, and perhaps their names, have been still different, but many existing studies have classified IC into three main categories consisting of human capital, structural capital, and relational capital, also called physical capital or capital employed (e.g., Andriessen & Tissen, 2000; Nielsen et al., 2006; G Roos & Roos, 1997; Stewart & Ruckdeschel, 1998; Sveiby, 1997; and among others) Accordingly, human capitalismostlyinvolvedtheintellectualprowessofindividualsinanorganizationanditcan be lost when employees leave companies In contrast to this element, structural capital is mainly engaged with policies, strategies, cultural aspects, possessed by firms Meanwhile, contrary to the first two elements, relational capital is totally related to the external factors such as multiplestake-holders.

2.2 Determination of the role of intellectual capital in business strategydevelopment

Historically and conventionally, both academicians and managers have endeavored to find out a clear reason why some businesses perform better while others do not The evident answer to this question may provide the key to opening new paths in managing the business strategy of firms (G Roos, 2005) Based on the theory of business strategy in the extant literature,theaimofthissubsectionistohighlightthevitalroleofICinconstructingbusiness strategy of firm industry in general and banking industry inparticular.

First of all, it is necessary to understand the meaning of “strategy” that a business leans on Theoretically, G Roos (2005) has identified “strategy” is seen as a series of approaches that assist businesses in accomplishing specific goals This author also underscores that the formulation of strategy will be depend specifically on the inventiveness coming from the human mind, while the action of strategy is to reach the strategic compromise between businessgoalsandenvironmentalrequirements,suggestingthatsellingproductsandservices has to meet demands of end-users Previously, Andrews (1997) considers that strategy of corporate can be seen as a mechanism of decision-making that helps to clarify the purposes, policies, as well as plans by which companies can reach their business goals From thev i e w

of this author, strategy brings significant contributions (both economic and non-economic values) to multiple stakeholders.

Now, a question is that why the level of profitability tends to be different between companies, regardless of whether they operate in a same area Looking carefully at the wave of business strategy development, it is argued that there are generally two main perspectives by which strategy may rely on (Marr & Roos, 2012) Accordingly, the first perspective is to focus mainly on the power of market, while the second one is to emphasize the efficiency of internal resources.

The former view of business strategy, namely“the paradigm of market power”, is seen

as the conventional strategy model leaning specifically on the power of market From this perspective, benefits a firm achieves may spring from the interaction of five major forces including the level of power that buyers have, the level of substitutes for both products and services, the level of power that suppliers possess, the capacity of entry into market, and the level of existing competition (Porter, 1980) These forces are stronger meaning that the profitability of a company will be lower (Marr & Roos, 2012; G Roos, 2005) The main argument of this view is that the fundamental difference in benefits of companies may come from the ability of barriers construction, also named “mobility barriers”, which will assist successful companies in protecting from imitation of their strategic models (Caves & Porter, 1977; Hatten & Hatten, 1987; Marr & Roos, 2012) In this light, the issue that may occur is how to create a set of forces to construct these barriers Rexhepi et al (2013) suggest thatthe answer may result from harnessing the intellectual capital of an enterprise when building business strategy, especially in industries relying much on this capacity such as educational and financial institutions.

Thelatterviewofbusinessstrategyisknownas“theparadigmofresource-basedmodel” is proposed and developed by some resource-rooted theorists such as Penrose & Penrose (2009); Wernerfelt (1984) This paradigm explains that the distinction of profitability may originate from the valuable resources that companies possess and the way they employ these resources Also, from this view, both resources and capacities are deemed as “the strategic assets” of enterprises The more strategic assets applied to a huge

services,thehigherbenefitsanorganizationcanachieve(Prahalad&Hamel,2009).However, it is argued that these resources and capacities cannot themselves producevalue-added

creation (Penrose & Penrose, 2009), hence, to create value, they have to be embedded into the both products and services that companies offer (Marr & Roos, 2012; G Roos et al., 2001) Such this sense has underscored the center role of IC in business strategy, because by leaning especially on IC view, the resources can be used effectively and companies can determine the way to which value-added creation (G Roos, 2005; G Roos et al., 2001).

Toillustratethisissueclearly,itshouldtakethebusinessoperationsofbanksasatypical example G Roos (2005) describes banks serve as conduits between clientele who needs financial support and a group of customers can fulfill this financial gap In this vein, banks have to organize the cash flow appropriately to balance demands of both types of these customers To perform this task well, banks have to transform various kinds of intellectual resources into effective remedies and solutions that will satisfy their clients G Roos (2005) also concludes that possessing valuable resources is not yet enough, instead, banks have to put these resources to value-addedcreation.

As Figure 2.2 illustrates above, the strategy map developed by (Kaplan & Norton, 2000, 2004) has depicted the causal connection between IC drivers and the performance of organizations,indicatingthefundamentalroleofICinconstructingbusinessstrategy.Inother words, the strategy map shows clearly the way by which IC can drive organizational objectives and outcomes of organizations These authors believe that by understanding the readinessofstrategicassets,decision-makerscanconstitutestrategicobjectives.Inshort,itis clear that by using intellectual capital, the resources of organizations can be transferred into the end products and services which, in turn, will distribute organizational values (Marr & Roos,2012).

In conclusion, along with the dramatic changes in business conditions, the strategy construction of an organization has to be adapted to suit the market needs, and the business perceptionofthepivotalroleofICindrivingvalue-addedcreationalsogrowsgradually(Marr

conventional paradigm to strategic assets model, in which, IC has emerged as the key engineforperformanceoutcomes,strategicobjectives,andsustainablevalue-addedcreations of most companies (Alvino et al., 2020) Therefore, leaders and managers in banks cannot neglect this pivotal factor in their business strategyconstruction.

2.3 Measure methods of intellectual capitalefficiency

In tandem with the persistent attempt to explain the concept and the strategic vehicle of IC as discussed above, it is also witnessed the numerous academicians have put their continuous energies into seeking out clearly the effective measure of IC efficiency It can be said that due to the core role of IC in companies' business strategies and operations,itsmeasurement has attracted many researchers in the financial sector and the existingliterature as awhole.

The urgent need to measure IC efficiency also originates from the realistic business strategies of firms that desire to manage IC in effective ways and disclosure this information frequently because, as the assertion of Bayraktaroglu et al (2019), managers only manage andcontrolanythingthattheyentirelymeasure.Inotherwords,“whenyoucanmeasurewhat you are speaking about and express it in numbers, you know something about it” (Liebowitz &S u e n , 2 0 0 0 ) T h e s e a r g u m e n t s h a v e u n d e r s c o r e d t h e p i v o t a l p a r t o f m e a s u r i n g I C i n

In the early stage, K.-E Sveiby & Lloyd (2010) and Luthy (1998) categorize the intangible measurement methods into the major four categories including ‘direct intellectual capitalmethods’,‘marketcapitalizationmethods’,‘ROAmethods’,and‘scorecardmethods’ These categories can be summarized asfollows.

The first category is directly connected with the aspect of “dollar value” coming from intangible resources, which is estimated by codifying its elements The second involves the calculationofIC’svaluethroughcomputingthedifferencebetweenthemarketcapitalization and the book value of the equity The third uses the ROA indicator to calculate the average annual earning springing from intangible assets The final is related to many indices developed from various components of IC to estimate IC’s value, but this approach does not evaluate the economic aspects like the firstcategory.

Meanwhile, according to Bayraktaroglu et al (2019) and Pew Tan et al (2008), the existing methods of IC measurement can be classified into the two major kinds consisting of thenon-financialcalculationor“non-dollarvaluation”andthefinancialcalculationor“dollar valuation” These both approaches have naturally embraced both merits and demerits Asthe given names of these categories suggest, while the former does not estimate the dollar valuation of IC, the latter gives the estimation of the dollar valuation.

SomemethodsintheformergroupmayincludetheSkandiaintellectualcapitalnavigator, intellectualcapitalindex,balancedscorecard,andamongothers.Inthisline,Kaplan&Norton

(1996)canbeseenasthetypicalpioneerstryingtoproposetheICmeasurement.Theauthors develop the balanced scorecard as the model to formulate IC, allowing managers to manage thecause-and-effectconnectionsbetweenintangibleassetsandbusinessperformancethrough the four views: customer, internal process, finance, and learning &growing.

Even though this model seems to be in line with the firm-specific view, it may not be appliedingeneralbecauseitmaynotevaluatethefinancialvalueoftheintellectualresources (Pew Tan et al., 2008) Hence, many methods have attempted to address this limitation,andamongdifferentmeasuresarebeingproposed.Amongofthem,mostscholarsreadilyconse nt that Skandia intellectual capital navigator is deemed as the measurement that provide a wide range of aspects to formulate IC, especially the role of customer relationships in the value- added creation (Bontis, 2001) Accordingly, this approach embraces around 112 indices reflected in five angles: customer, finance, human, process, renewal and development However, this method does not evaluate dollar values ofIC.

To sum up, the non-financial perspective allows researchers and managers to determine thewhattypeofICcomponentsandtheirimpactsonbusinessoperationsoffirms,butitdoesnot help to formulate the economic values of intangible assets (Bayraktaroglu et al.,2019).

On the other hand, the financial perspective such as the economic value added, Tobin’s Q, VAIC model, and extended-VAIC model, has focused mainly on the economic value of intangible assets that an organization owns, hence it enables both scholars and business leaders to evaluate IC’s performance and compare it to rivals (Bayraktaroglu et al., 2019).

For instance, the economic value added capturing many variables including financial plan, performance, budget, shareholder communication, and incentive compensation emphasizesthemaximationofearningsovercosts.However,oneofthismethod’sdrawbacks is that it leans much on historical expenses that does not capture immediately the current market value (Bontis, 2001; Pew Tan et al.,2008).

Another compelling method is the value-added intellectual coefficient (VAIC) model of Pulic (1998, 2000), which is seen as a relatively simple to calculate and is widely used in the preceding literature (Adesina, 2019; Nazir et al., 2021) As a claim by Poh et al (2018), the

value-added intellectual coefficient model (VAIC) is suitable for the banking and financial sector and other industries.

This method was created and developed by Pulic (1998, 2000, 2004), and utilized in a wide range of studies on the role of intellectual capital in the banking industry and other disciplines (e.g., Adesina, 2019; Le & Nguyen, 2020; Meles et al., 2016; Nazir et al., 2021; Ozkan et al., 2017; Poh et al., 2018; Yalama, 2013; and among others) This model would consist of three main components: capital employed efficiency (CEE), human capital efficiency (HCE), and structure capital efficiency (SCE) This approach reflects the creation of value in each money a company spends and the efficiency of intellectual capital utilized Therefore, a higher value of VAIC means that using a firm's resources becomes better effective.

Inthisstudy,theauthorwouldutilizeVAICmodeltomeasureICefficiencyinbanksand acting as the main explanatory variable in the analysis models For calculation, the detailed explanation would be stated in the methodology chapter Along with that, this chapter also acknowledges the drawbacks of VAIC model and gives detailed explanations about some

2.4 Theoretical background of intellectualcapital

There are some potential theories which could interpret the connection between IC and financial intermediation and non-interest incomes in banks.

Based on the assumption that knowledge embedded in individuals is considered an asset oforganizations,thehumancapitaltheorydevelopedbyEdvinsson&Malone(1997);Stewert (1999) suggests that any company should explore this intangible resource to create and acquire competitive leverage in the market The underlying assumption of this theory isthatby tapping into the knowledge embedded into each individual and team, organizations can harness these assets and transform them into advantageous competition in the today’s economy (Stewart & Ruckdeschel,1998).

AccordingtoHarris(2000),theknowledgecanbedividedintotwomajortypesincluding tacit term and explicit term In terms of the tacit knowledge which is considered the most significanttype,Harrisstatesthatitmayconsistofexperiences,beliefs,perceptions,learning and similar items that are being embedded into employees and are notspoken.

includes procedures, guides, policies written down Allee (1997) asserts that nearly 90%ofknowledgeownedbyfirmsmayspringfromthetacitknowledge,thereforetoharness intellectual resources effectively, firms need to transform this type of knowledge into the explicit one In other worlds, an increase in the rate of the explicit knowledge is quite the important issue when exploring intellectualcapital.

On the other hand, the systems theory considers that each individual has to interact with general processes and businesses to meet the consistent goals of an organization (Heylighen &Joslyn,1992).Inthisvein,ICwouldbecomeanappropriateenvironmenttoensureconstant information flows within the organization and customer communication (Harris, 2000) Relying on this knowledge-sharing mechanism, managers could enhance and even adjustthe orientation as well as navigation of business plans to satisfy the demands of their clientele (Harris,2000).

In other words, each knowledge of each member in a company will emerge as the heart of knowledge for relevant others because individuals become a pivotal part of strategic role invalue-addedcreation(Senge,1991).Moreclearly,Harrisdepictsthatthesystemsapproach deems the human capital and systems as two interconnected and integrated entities which serve as the foundation for the performance enhancement of acompany.

achieve an increase in financialintermediation.

To identify clearly the intended correlation between IC and financial intermediation as well as non-interest incomes, relying on the models constructed by Edvinsson & Malone (1997) and Suciu & Năsulea (2019), the study would reconstruct these models to draw the possible illustration of these relations in Figure 2.2.

As this picture illustrates, through three main ingredients: human capital, structural capital, and relational capital, IC would have certain influences on financial intermediation activities in several channels as follows.

First,itisclearthatasthehumantheoryhasindicated,bytappingintothetacitknowledge of employees, any organization may transfer these implicit resources into the innovative capitalthatiseventuallyharnessedtoaccomplishcompetitiveadvantagesinmarkets.Second,

thestructuralcapitalwouldfuelcompetitivenessthroughthechannelofsocialcapital.Indeed, Suciu & Năsulea (2019) argue that in the digital, innovative, and knowledge-based era, structural capital would assist enterprises to build evolutionary adaptations to meet current challenges Such new adjustments could enhance and strengthen the process capital of companies, and therefore, they could achieve substantial improvement in competitive abilities.

To explain the last channel, these authors assert that increasingly interacting with multi-stakeholders and facing differences in culture, each organization nowadays has to possess a deeper understanding of the fundamentals of the culture of excellence By relying much on the intangible resource, namely IC, enterprises could construct or re-construct the solid foundation, which would help them explore multi-dimensions of cultures, societies, and environments This improved backbone would bring sustainable development and competitiveness to modern firms.

In short, based on these channels, it is indisputable that IC and its components are expected to provide competitive advantages for companies Thus, the activities of financial intermediation and non-interest income would be fueled by these precious resources in the today’s modern world.

2.5 Related empirical studies in the bankingindustry

As the author mentioned before, although harnessing IC as the key vehicle to accomplish competitiveness in the banking market and perhaps in other disciplines is widely recognized by scholars and theorists in the preceding literature, the empirical evidence inthe banking sector seems relatively scarce compared with other industries (Le & Nguyen,2020) However, regardless of certain obstacles, especially regarding necessary data, there are numerous endeavors to discover this vitalfield.

Itcanbesaidthat,ontheonehand,awiderangeofempiricalinvestigationsinthebanking industry tend to employ VAIC model proposed and developed by Pulic (1998, 2000) as the dominated tool to calculate IC efficiency of banks On the other hand, the empirical results tend to maintain the open questions in which while enormous papers lend to advocate the relationship between VAIC model and banking performance, the opposite view is alsofound
