Intellectual capital and financial performance of industrial firms in emerging countries: Empirical evidence from Vietnam

Nguyet Thi Nguyen,Van Thi Nghiem 사람과세계경영학회 2023 Global Business and Finance Review Vol.28 No.2

Purpose: This study contributes evidence on the impact of IC and its components for emerging countries, the case of Vietnam. Design/methodology/approach: The research measures the value-added intellectual coefficient and applies the two-step system GMM model for the period 2005-2014. Findings: Findings imply that IC contributes significantly to the industrial firm performance. Industrial firm performance is positively affected by Human capital efficiency (HCE) and Capital Employed Efficiency (CEE). Generally, Structural capital efficiency (SCE) has an insignificant effect on the industrial firm performance. Impact of IC efficiency depends on the internal and external factors. The impacts of IC efficiencies differ among levels of knowledge intensity. Generally, HCE is more important than CEE. The impact of IC on industrial firm outcomes depends on knowledge intensity levels. The more knowledge intensive, the stronger impact of IC is. Only high knowledge intensive firms benefit from all three components of IC efficiency. HCE and CEE are most effective for firms with high knowledge intensity. SCE is strongest for firms at low knowledge intensity. Only CEE contributes to industrial firms at all knowledge intensity levels. HCE is insignificant for firms at low knowledge intensity, while SCE is insignificant for firms at medium level. Research limitations/implications: The paper examines only one variable representing for firm financial performance, ROA. Controlled variables are only at industrial level, not at broader levels, such as provincial or national levels. Originality/value: Investigating IC will contribute to literature of levels of investment in tangible and intangible assets. It helps firm leaders and policymakers to comprehend the significant role of IC as well as the knowledge economy, then properly reallocate intellectual resources. Firm leaders and policymakers should focus on HCE and CEE which driver significantly value added. The findings suggest firm leaders which component of intellectual capital they should invest corresponding to various level of knowledge intensities.

Nguyet Nguyen,Thi Hoang Ha Tran The International Academy of Global Business and T 2023 The International Academy of Global Business and T Vol.19 No.5

Purpose - Based on personality - job fit theory (Kristof-Brown, 2006) and social exchange theory (Blau, 2017) we explaine evidence of the relationship between proactive personality, proactive feedback seeking behavior, and the job performance of platform workers. We also examine the moderating role of perceived organizational support in relationship between proactive personality and feedback seeking behavior and job autonomy as a moderating role between the proactive feedback seeking behavior and job performance of platform workers. Design/Methodology/Approach - This study follows structural equation modeling following a partial least square method on a sample group of 171 platform workers selected by convenient random sampling techniques and analyzed by SmarlPLS 4.0 to test research hypotheses. Findings - Research findings show that proactive personality plays an important role in promoting proactive behavior seeking feedback and job performance, and affirms the positive moderating role of perceived platform support between feedback seeking behavior and proactive personality. The study also confirmed that proactive feedback seeking behavior has a direct and indirect impact on the performance of platform workers, and this relationship is further strengthened in conditions of highly autonomous work. Research Implications - Some implications of human resource management on digital labor platforms are also proposed to improve the efficiency of human resource management.

( Nguyet Pham ),강성구,이승걸 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.0

We investigated the effect of graphene quantum dot (GQD) in metallophalocyanine on ORR activity by using density functional theory (DFT). Throughout all calculations, the rate-limiting step in MnPc, MnPc/GQD and FePc in oxygen reduction process is OOH* formation, meanwhile that of OH* formation in FePc/GQD. We conclude that all MnPc, FePc, MnPc/GQD and FePc/GQD would be able to facilitate 4epathway, and the presence of GQD enhances the ORR performance of monolayer systems. ** This research was supported by the NRF of Korea funded by the Ministry of Science, ICT & Future Planning (Nos.

Nguyet Minh NGUYEN,Kien Trung TRAN 한국유통과학회 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.11

The aim of this article is to determine the influence of factors on the capital structure of construction companies listed on the Hanoi Stock Exchange. The data of the article were collected and calculated from the financial statements of 54 construction companies listed on Hanoi Stock Exchange from 2012 to 2019. With the application of E-view software in quantitative analysis to build panel data regression model (panel data), the article has built a regression model to determine the relationship of intrinsic factors affecting the capital structure of construction companies listed on Hanoi Stock Exchange. In the study, dependent variable is capital structure, determined by the debt-toequity ratio. Profitability, coefficient of solvency, size, loan interest rate, structure of tangible assets, and growth are independent variables. The results showed that the two factors of growth and firm size positively affect the capital structure, the profitability factor has the opposite effect on capital structure. Factors of short-term debt solvency, average loan interest rate and tangible asset structure have no correlation with capital structure. The findings of this article are useful for business administrators, helping business managers make the right financial decisions to make capital structure decisions in their own conditions.

<P><B>Abstract</B></P> <P>While an anti-allergic effect of Chaga mushroom (<I>Inonotus obliquus</I>) has been indicated, its therapeutic effect on allergy and immunoregulatory mechanisms and chemical constituents directly responsible for that are hardly known. We examined the effect of 70% ethanol extract of Chaga mushroom (EE) and its dichloromethane (DF) and aqueous (AF) fractions using a mouse model of chicken ovalbumin (cOVA)-induced food allergy, and found that only EE and DF ameliorated allergy symptoms to a significant extent. The in vivo mast cell-stabilizing activity was also found only in EE and DF whereas the activities to suppress Th2 and Th17 immune responses and cOVA-specific IgE production in the small intestine were observed in all three treatment regimens, implying that inhibition of the mast cell function by lipophilic compounds was vital for the therapeutic effect. Results also indicated that inotodiol, a triterpenoid predominantly present in DF, played an active role as a mast cell stabilizer.</P> <P><B>Highlights</B></P> <P> <UL> <LI> 70% EtOH extract of Chaga mushroom has a good therapeutic effect on food allergy. </LI> <LI> A Mast cell stabilizing activity is key for the effect of Chaga mushroom. </LI> <LI> Only CH<SUB>2</SUB>Cl<SUB>2</SUB> fraction, but not H<SUB>2</SUB>O fraction, has the mast cell stabilizing activity. </LI> <LI> Inotodiol, a tetracyclic triterpenoid, is predominantly present in CH<SUB>2</SUB>Cl<SUB>2</SUB> fraction. </LI> <LI> Inotodiol holds a strong mast cell stabilizing activity. </LI> </UL> </P>

Economic Integration in ASEAN+3: A Network Analysis

( Thi Nguyet Anh Nguyen ),( Thi Hong Hanh Pham ),( Thomas Vallee ) 세종대학교 경제통합연구소 2016 Journal of Economic Integration Vol.31 No.2

This paper analytically and graphically explores the characteristics of ASEAN+3’s trade and Foreign Direct Investment integration over the 1990~2012 period by applying the tools of network analysis. Our results find evidence that the degree of trade and Foreign Direct Investment integration varies among ASEAN+3 member countries over the observation period. Second, ASEAN+3’s intra-regional trade network seems to be more densely connected than its intra-regional Foreign Direct Investment network. Third, we reveal that large and/or advanced countries seem to be better linked and form a subregional bloc of tightly connected economies only in terms of export absolute value. Therefore, ASEAN+3 has been experiencing a widening gap in the trend and patterns of intra-regional trade and Foreign Direct Investment among its member countries at different levels of economic development.
