Abstract:
This study investigates w88 link mới nhất influence of intellectual capital on Vietnamese bank performance from 2011 to 2023. To calculate intellectual capital, we used w88 link mới nhất value of w88 link mới nhất intellectual coefficient. We employed various panel methods and eventually chose w88 link mới nhất system GMM estimator to evaluate our baseline results. According to w88 link mới nhất findings, w88 link mới nhất value of w88 link mới nhất intellectual coefficient positively influences bank performance. Furthermore, when observing w88 link mới nhất effect of intellectual capital’s components (i.e., capital employed, human capital employed, and structural capital employed efficiency), they considerably enhance bank performance. As a result, w88 link mới nhất research has substantial implications for management and academics. For instance, it implies that bank managers should focus on intellectual capital and its components to strengthen bank performance further.
Keywords: intellectual capital, Value intellectual coefficient, capital employed efficiency, human capital employed efficiency, and structural capital efficiency.
1. Introduction
For economic growth to occur, a sound financial system is required. w88 link mới nhất banking industry is often recognized as w88 link mới nhất most powerful sector within a financial system (Haris et al., 2019). w88 link mới nhất Vietnamese banking sector has faced numerous hurdles and political changes since w88 link mới nhất country's independence in 1945. Vietnamese banks suffer from poor public policy and w88 link mới nhất lack of international audits. Since 1992, w88 link mới nhất Vietnamese banking system has comprised a mix of state-owned, joint-stock, joint-venture, and international banks (Ho et al., 2021). In September 2005, w88 link mới nhất Vietnamese central bank decided to equitize all five state-owned banks to maximize w88 link mới nhất transparency of w88 link mới nhất financial industry (Le & Ngo, 2020). Since 2007, w88 link mới nhất State Bank of Vietnam has permitted foreign banks to offer a complete range of financial services as Vietnamese banks (c). As a result, it leads to fierce competition in w88 link mới nhất banking market, thereby affecting Vietnamese banks’ income. Therefore, domestic banks need to improve intellectual capital (IC) efficiency.
Most bank studies (Al-Musali and Ismail, 2016) concluded that bank- and country-specific variables influence FB significantly, but these studies ignored w88 link mới nhất role of IC (Haris et al., 2019). This study is w88 link mới nhất first attempt to use w88 link mới nhất Value Intellectual Coefficient (VAIC) model to evaluate w88 link mới nhất influence of IC on FB of 26 Vietnamese banks from 2011 to 2023. Most recent research that has used w88 link mới nhất VAIC model created by Joshi et al. (2013) has concluded that VAIC is a simple-to-use and effective tool for assessing w88 link mới nhất influence of IC on FB.
w88 link mới nhất study aims to contribute to w88 link mới nhất field of bank management as follows. First, this study builds on earlier research by revealing w88 link mới nhất importance of VAIC components in delivering outstanding banking system performance in a dynamic setting. Second, it assesses and measures w88 link mới nhất influence of bank-specific and macro variables on performance. Finally, because Pool Ordinary Least Square (OLS), Fixed Effects (FE), and Random Effects (RE) do not address heteroskedasticity and autocorrelation, w88 link mới nhất study introduces GMM, which is used to pass difficulties in data analysis. In summary, this study develops and verifies models of w88 link mới nhất interactions between VAIC dimensions, bank-specific variables (BSVs), and macro variables (MVs).
2. Literature Reviews
2.1. Intellectual capital
In 1969, John Kenneth Galbraith, an economist, developed w88 link mới nhất initial definition of IC. Galbraith defines IC as an intangible asset. Others say that IC encompasses all knowledge, information, intellectual property, experiences, social networks, abilities, and competencies contributing to corporate performance (Subramaniam & Youndt, 2005).
IC comprises three components: human, structural, and relational capital. Human capital is defined as w88 link mới nhất sum of an employee's abilities, skills, experience, and educational background. Structural capital refers to w88 link mới nhất institutionalized knowledge and codified experiences preserved in an organization's image, culture, routines, processes, information systems, and patents (Gilbert et al., 2017). Coleman (1988) describes relational capital as w88 link mới nhất resources in social networks where individuals or organizations interact.
2.2. VAIC and Bank Performance
w88 link mới nhất VAIC model is widely used for calculating IC performance. There are w88 link mới nhất following three components used to determine w88 link mới nhất value of VAIC: (1) capital employed efficiency (CEE), (2) human capital employed efficiency (HCE), and (3) structural capital efficiency (SCE) (Haris et al., 2019). Human capital and structural capital efficiency are measured by HCE and SCE (Rehman et al., 2021).
w88 link mới nhất study will examine w88 link mới nhất linkage between IC efficiency and FB by using CEE, SCE, and HCE as indices of IC efficiency. On w88 link mới nhất other hand, return on assets (ROA) and return on equity (ROE) are utilized as indicators of FB. Numerous studies have been undertaken using w88 link mới nhất VAIC model to examine w88 link mới nhất relationship between IC efficiency and FB; however, their results are mixed. Rehman et al. (2021) discovered a good association between w88 link mới nhất VAIC and ROA of Islamic banks in 23 nations. w88 link mới nhất outcome of w88 link mới nhất study by Haris et al. (2019) in Pakistan and w88 link mới nhất United States indicated a positive connection between VAIC and ROE. Although CE and HCE also have positive influences on FB (Al-Musalli & Ku Ismail, 2016; Joshi et al., 2013), HCE has w88 link mới nhất most significant impact on FB. Therefore, w88 link mới nhất hypothesis is suggested:
H1: Intellectual capital has a positive influence on FB.
H2: Intellectual capital components (CEE, HCE, and SCE) have positive influences on FB.
3. Methodology
3.1. Data Source
Financial reports of Vietnamese commercial banks from 2011 to 2023 were used to compile bank-level data. Banks with 100 % foreign ownership are excluded to ensure that w88 link mới nhất results are comparable. Despite w88 link mới nhất author's desire to collect data from all 31 commercial banks, only 26 banks have sufficient data for at least thirteen years. In addition, w88 link mới nhất paper also employs country-level data from w88 link mới nhất General Statistics Office.
3.2. Variable Selections
3.2.1. Dependent variables
Le & Ngo (2020) and Tan et al. (2017) conducted research using two earnings metrics: ROA and ROE. w88 link mới nhất ROA is computed by dividing net income by average assets, and it represents how capable w88 link mới nhất bank is of generating revenue by using assets. ROE = net earnings / average equity.
3.2.2. Independent variables
Current literature suggests different approaches to measuring intellectual capital. w88 link mới nhất VAIC, w88 link mới nhất conventional methodology created, is a suitable and trustworthy proxy for assessing IC's impact. w88 link mới nhất author uses VAIC as an independent variable, as in previous investigations (Xu and Wang, 2018;). w88 link mới nhất following formula is used to compute it:
VAICit = CEEit + HCEit + SCEit (1)
where VAICit denotes w88 link mới nhất VAIC of ith banks at time t. CEEit represents w88 link mới nhất CEE (capital employed efficiency) of bank i at time t, HCEit refers to w88 link mới nhất HCE (human capital efficiency) of bank i at time t and SCEit refers to w88 link mới nhất SCE (structural capital efficiency) of bank i at time t, respectively. However, to calculate w88 link mới nhất variables above, it is necessary to compute w88 link mới nhất value-added (VA) amount to measure w88 link mới nhất VAIC decompositions (Ozkan et al. 2017, Xu and Wang, 2018), which is:
VAit = OPit + PCit + Dit + Ait (2)
where VAit refers to w88 link mới nhất value made by ith bank at time t; OPit refers to w88 link mới nhất operating profit of a bank i at time t; PCit represents w88 link mới nhất total cost of salaries and other benefits of w88 link mới nhất ith bank at time t. Dit refers to w88 link mới nhất depreciation expense of ith bank at time t; Ait means w88 link mới nhất amortization and depreciation expenses of ith bank at time t.
Once VAit is calculated, w88 link mới nhất VAICit components are measured as follows:
CEEit = VAit / CEit (3)
where CEi represents capital held by a bank and is calculated by w88 link mới nhất difference of total assets and total liability).
HCEit = VAit / HCit (4)
where HCit represents human capital calculated by w88 link mới nhất sum of salary and all other expenses incurred on employees.
SCEit = SCit / VAit (5)
where SCit representing structural capital is computed by w88 link mới nhất difference of VAit and HCit (SCit = VAit - HCit).
3.2.3. Control and Dummy Variables
This article investigates w88 link mới nhất influence of BSVs (bank-specific variables) and MV (macroeconomic variable) on profitability (ROA and ROE). In this study, bank size (BSIZE) is computed by w88 link mới nhất natural logarithm of total assets (Tan et al, 2017) and total debt / total assets is LEV to assess w88 link mới nhất influence of BSVs (Ozkan et al., 2017).
w88 link mới nhất dummy variable bank type (BTYPE) is also used in w88 link mới nhất study to examine ownership effects (Haris et al., 2019). If w88 link mới nhất bank is privately owned, BTYPE is 1; otherwise, it is 0. w88 link mới nhất growth rate of w88 link mới nhất gross domestic product (GDP) is used by MV to control w88 link mới nhất influence of economic growth (Haris et al., 2019).
3.3. Regression Models
w88 link mới nhất authors propose four models as follows.
ROAit = β0 + β1 VAICit + β2 BSIZEit + β3LEVit + β4 BTYPE + β5 GDP + εit
ROEit = β0 + β1 VAICit + β2 BSIZEit + β3LEVit + β4 BTYPE + β5 GDP + εit
ROAit = β0 + β1HCEit + β2 SCEit + β3CEEit + β4 BSIZEit + β5LEVit + β6 BTYPEit + β7 GDPt + εit
ROEit = β0 + + β1 HCEit + β2 SCEit + β3CEEit + β4 BSIZEit + β5LEVit + β6 BTYPE it + β7 GDPt + εit
4. Results
4.1. Descriptive statistics
w88 link mới nhất paper used data of 26 Vietnamese banks from 2011 to 2023, resulting in 37 observations.
For ease of interpretation, we pay attention to our main variables. According to Table 3, w88 link mới nhất average ROA and ROE percentages are 0.1812 (18.12%) and 0.1345 (13.45%), respectively. w88 link mới nhất results indicate that w88 link mới nhất banks generate 0.1812 VND and 0.1345 VND for every Vietnamese currency of assets and equity used. It implies that Vietnamese banks have not utilized their assets or equity to make profits (less than 20%). w88 link mới nhất average value of VAIC is 5.1452, implying that Vietnamese banks generate 2.8452 VND for every Vietnamese currency of IC used. HCE is w88 link mới nhất most important component among CEE, HCE, and SCE, with an average value of 4.9151 compared to 0.3512 and 0.5173, respectively, for CEE and SCE. This is comparable with those of Ozkan et al. (2017) in Turkey and Tran & Vo (2020) in Thailand. Other variables are presented in Table 2.
4.2. Correlation analysis
Table 1 demonstrates that VAIC has positive correlations with ROA and ROE. In addition, CEE, HCE, and SCE also have strong links to VAIC.

In w88 link mới nhất next step, w88 link mới nhất Hausman (1978) test is used to determine which model, w88 link mới nhất FE or RE model, is appropriate for regression. w88 link mới nhất outcomes in Table 2 show that w88 link mới nhất null hypothesis (H0) is not accepted for all, so w88 link mới nhất FE model is inconsistent. Therefore, w88 link mới nhất FE model is appropriate for Vietnamese banks.

4.3. Fixed effects
w88 link mới nhất connection between VAIC, CEE, HCE, SCE, and ROA, as well as ROE, is shown in Table 4. CEE, HCE, and SCE are more effective at explaining FB than VAIC alone, according to w88 link mới nhất findings. Table 3 shows that when VAIC is broken down into CEE, HCE, and SCE, CEE has w88 link mới nhất greatest effect on Vietnamese bank performance, which is in line with Xu, Haris, and Yao's (2019) argument. w88 link mới nhất performance of banks is also influenced by HCE and SCE.
Table 3. Fixed effects regression
Source: Stata 15.0
However, in addition to w88 link mới nhất FE model, w88 link mới nhất authors use w88 link mới nhất Wooldridge and Modified Wald tests to see if autocorrelation and heteroskedasticity are present in w88 link mới nhất four models. w88 link mới nhất results show that in four models, both autocorrelation and heteroskedasticity are present. As a result, in four research models, using w88 link mới nhất FE model does not fix autocorrelation and heteroskedasticity.
4.4. Generalized method of moments (GMM)
Xu et al. (2019) argued that GMM (Table 4) may deal with issues about heteroskedasticity, autocorrelation, and endogeneity. Because GMM allows for w88 link mới nhất use of instrumental variables and lagged variables, valid instruments must be used to ensure that w88 link mới nhất GMM results are consistent. w88 link mới nhất following are extended regression models based on GMM shown in Table 5.
Table 4: Econometric models based on GMM
Source: Stata 15.0
w88 link mới nhất test results of models e, f, g, and h are shown in Table 6 below. w88 link mới nhất outcome confirms that w88 link mới nhất instrumental variables are not endogenous in all models in this study. Furthermore, w88 link mới nhất results also show that second-order autocorrelation is insignificant, so it makes GMM estimation valid. w88 link mới nhất results also show that FB (ROA and ROE) is affected significantly by past year performance (ROAt-1 and ROEt-1). w88 link mới nhất result also illustrates that a one-year lagged VAIC (VAICt-1) has a significant influence on ROA and ROE, respectively. However, it has a smaller influence than w88 link mới nhất current year VAIC. CEEt-1, HCEt-1, and SCEt-1 have a less significant influence on ROA and ROE than CEE, HCE, and SCE. After all things considered, we confirm that w88 link mới nhất results shown in Table 5 are w88 link mới nhất best optimal.

5. Discussion
CEE, HCE, and SCE also have positive influences on bank profitability (ROA and ROE), respectively, which is consistent with a study by Tran and Vo (2020). However, this argument contradicts w88 link mới nhất research of Xu et al. (2019) on w88 link mới nhất Chinese and Pakistan banking sectors. HCE has positive influences on profits (ROA and ROE) and this result is not in line with w88 link mới nhất research of Vo (2018) about Thailand’s banking system. w88 link mới nhất results also show that FB (ROA and ROE) is affected significantly by past year performance (ROAt-1 and ROEt-1). We also obtained that VAICt-1, CEEt-1, HCEt-1, and SCEt-1 have positive impacts on ROA and ROE, but their impacts are less significant than current CEE, HCE, and SCE. These are consistent with w88 link mới nhất research of Tran and Vo (2020) and indicate that banks must continuously improve IC if they would like to maintain superior FB in w88 link mới nhất long term.
Regarding control variables, w88 link mới nhất significant and positive coefficients of BSIZE demonstrate that larger banks perform better than smaller counterparts. This is contrary to w88 link mới nhất findings of Le & Ngo (2020). Also, banks with higher leverage earn higher profitability regardless of w88 link mới nhất measures, consistent with w88 link mới nhất study of Ozkan et al. (2017). Further, w88 link mới nhất coefficient of BTYPE is positive and significant, implying that privately owned banks are more profitable than state-owned banks. It can be explained that state-owned banks usually apply lower interests in both loans and deposits than w88 link mới nhất others, and have to subsidies other private businesses, driving them to have lower net incomes. Finally, GDP is positive and significantly associated with bank profitability, stating that economic growth enhances profitability as generally perceived. This is in line with w88 link mới nhất existing literature (Ho et al., 2020).
6. Conclusions
Nowadays, IC is widely recognized as a source of competitive advantage and future value creation in today’s knowledge-based economy. By using w88 link mới nhất VAIC approach, first, this study examines w88 link mới nhất influence of IC on Vietnamese bank performance (ROA, ROE) from 2011 to 2023. Second, this paper focuses on how IC and its components influence ROA and ROE using w88 link mới nhất GMM method. Lastly, w88 link mới nhất effect of IC at these institutions is then investigated in this paper. w88 link mới nhất baseline result reveals w88 link mới nhất following: (1) IC has a positive effect on FB, (2) CEE is w88 link mới nhất key driver of profit in Vietnamese banks, and (3) w88 link mới nhất lagged CEE, HCE, and SCE have a significant influence on FB.
Several practical contributions are suggested in this work. To begin, w88 link mới nhất current analysis indicates that w88 link mới nhất bank should invest in IC resources to increase profitability. Because banks provide financial services that necessitate sophisticated information systems and good procedures. As a result, bank executives must be cognizant of w88 link mới nhất relevance of IC and manage it efficiently to generate additional value. Second, w88 link mới nhất empirical data demonstrate that Vietnamese banks rely heavily on physical and financial resources (CEE) to generate profits, thus managers need to make effective use of these resources to improve performance. Third, because w88 link mới nhất banking industry is a knowledge-intensive industry, it necessitates highly skilled and well-trained individuals (HCE) to handle financial intricacies and establish strong relationships with stakeholders to resolve agency issues. As a result, investing in human capital has a lot of potential to boost bank profits. Finally, because SCE has a big influence on FB, Vietnamese banks place a premium on value creation through maintaining positive customer connections and enhancing company reputation.
There are certain drawbacks that need to be address. Firstly, international banks are not mentioned in w88 link mới nhất bank list. Second, both relational and inventive capital are ignored. Finally, w88 link mới nhất analysis ignores w88 link mới nhất link between intellectual capital and other bank characteristics. Therefore, these will be completed in w88 link mới nhất future.
