This study aims to analyze the impact of transformational leadership on the performance of small and medium enterprises in Can Tho city, Vietnam. This research is based on the theory and the four components of Transformational Leadership Theory (TLT) (Idealized Influence - II; Inspirational Motivation - IM; Intellectual Stimulation - IS; Individualized Consideration - IC), a review of related studies, and opinions from expert interviews to develop a research model. The primary data of the article was collected from a survey of 214 small and medium enterprises in the city. The data analysis methods used in this study include Cronbach's alpha reliability test, confirmatory factor analysis (CFA), structural equation modeling (SEM), and multigroup structural analysis. The article's research results confirm that the leaders of enterprises with a transformational style play a significant and positive role in the spirit of learning and sharing knowledge of the organization members, especially the micro-enterprises face many difficulties due to the lack of resources. Research results also show that thanks to the transformational leadership (TL) style and organizational learning (OL), it has made an essential contribution to organizational innovation (OI) as well as to improving operational efficiency (both financial and non-financial performance) for small and medium enterprises in Can Tho city. Based on the article's research results, the authors have proposed some characteristics of transformational leaders in small and medium enterprises in the city. In particular, the study emphasizes the influence of the individualized consideration and idealized influence factors in improving learning ability, contributing to organizational renewal and improving performance for small and medium enterprises in Can Tho city.</p> Dinh Cong Thanh Pham Le Hong Nhung Le Tan Nghiem Le Trung Ngoc Phat ##submission.copyrightStatement## 2022-04-11 2022-04-11 6 2 2357 2372 10.32508/stdjelm.v6i2.866 title description none g Applying machine learning for hand posture recognition from a series of depth images <p>Image recognition one of the most difficult issue, is becoming an applied research in recent times. The possibility of allowing computers to recognize human’s hand posture in real-time is gradually becoming popular and involved in many fields. It is also integrated into so many products. Thus, this study proposes an approach for faster and more accurate image recognition. With the development of technology, this camera device has had many significant changes; the camera can capture both RGB images and images in depth. This makes identification in low-light conditions more accurate, which improves recognition performance. The Random Forest algorithm is evaluated to be more efficient, faster, and more accurate than previous recognition algorithms used for model testing. We collected about 10,000 hand image data samples, then trained and evaluated the model with nearly 80% accuracy results. In addition, the study presents some results of gesture recognition of human hands in real-time using information obtained from Kinect sensor; the model has the ability to train quite large data and the recognition speed is faster. Research results can be used in control applications serving in life and industrial production.</p> Phạm Minh Lộc Nguyễn Văn Hồ ##submission.copyrightStatement## 2022-04-11 2022-04-11 6 2 2373 2385 10.32508/stdjelm.v6i2.870 title description none g Factors that impact brand awareness of student events’ sponsors among students in Vietnam <p>This study aims to determine and analyze the relationship between factors of sponsoring student events and brand awareness of the sponsors among students in Vietnam. Based on 3 related models: Determinants of Sponsorship Response Model, Sponsorship Evaluation Scale and Role of Sponsorships in Developing Brand Equity Model, this study generates a conceptual framework about factors that affect brand awareness of student events’ sponsors among students in Vietnam. Data of this study is collected by conducting a survey from students which obtains 473 valid responses. The reliability of the scale is assessed by Cronbach's Alpha test, EFA testing the accuracy of observed - variable grouping, and multivariate regression used to measure the impact of factors on brand awareness. Ultimately, the results illustrate that Brand Awareness is positively affected by 6 factors including "Status of the Event'', "Personal Liking for the Event", “Sponsor-Event fit”, “Attitude toward Sponsor”, “Sincerity of Sponsor”, and “Image of Sponsor”, and negatively affected by 1 factor “Ubiquity of Sponsor”; “Sponsor-Event fit” is the most dominant factor impacting on students' brand awareness.</p> Phan Lam Quỳnh Vũ Trí Đức Trần Thảo Nguyên Nguyễn Thúy Vy Trần Gia Huy ##submission.copyrightStatement## 2022-04-11 2022-04-11 6 2 2386 2399 10.32508/stdjelm.v6i2.871 title description none g The relationship between psychological capital, job satisfaction and organisational commitment of officers – Empirical Evidence from fisheris sub-department of Kien Giang province <p>The study aims to analyze the relationship between psychological capital, job satisfaction, and organisational commitment of officers woking at the Fisheries Sub-Department of Kien Giang province.

The rapid growth of population and the residents migrating to big cities have resulted in increasing housing demand. Housing needs for people in big cities in general and in Ho Chi Minh City, in particular, are becoming more and more urgent, especially, apartment buildings because of limited land fund of the locality. Analyzing factors affecting the customers’ post-purcahse bahavior is useful for real estate companies. To examine the causal relationship among perceived risk, perceived quality, customer satisfaction, and post-purcahse behavior, This research used structural equation modeling (SEM) to analyze 412 samples who bought apartments in Ho Chi Minh City. The results showed that the post-purchase behavior towards apartments is directly affected by satisfaction and indirectly by factors: perceived quality, perceived risk, location, after-sales support, price, and brand. And the study provided recommendations to enhance customer satisfaction influence post-purchase behavior towards apartments.</p> Phùng Thanh Bình Trần Thị Thanh Na Dang Hai Ha ##submission.copyrightStatement## 2022-04-11 2022-04-11 6 2 2414 2426 10.32508/stdjelm.v6i2.919 title description none g The impact of authentic leadership on employee’s engagement at Tan Son Nhat Operation Center in the COVID-19 period: The mediating role of job satisfaction <p>Human resources is one of the important resources to promote the development of enterprises in the aviation sector in Vietnam. Therefore, airline firms are increasingly interested in job satisfaction and employee engagement. Aviation is a sector of special importance in economic development. Before the COVID-19 pandemic, the aviation sector developed strongly. However, when the COVID-19 pandemic broke out, the world economy suffered from enormous damage, with the first hardest-hit sector being air transport. Vietnam's aviation sector was also not an exception from the impact of the COVID-19 pandemic, according to a report by the Ministry of Planning and Investment, which said that in 2020 and the first 5 months of 2021, the revenue of aviation enterprises decreased by 61% compared to that of 2019. In Vietnam Airlines Annual report 2020, Vietnam Airline had more than 100 aircraft temporarily suspended from operation. Tan Son Nhat Operation Center was a unit of Vietnam Airline JSC with the role of a representative at Tan Son Nhat airport, which was also affected by many related impacts. In a difficult period, the role of leadership in general and authentic leadership in particular was very important in improving employee satisfaction and engagement. This research investigated and tested affecting authentic leadership on employee engagement at Tan Son Nhat Operation Center in the covid-19 period: the mediating role of job satisfaction. It uses both qualitative and quantitative research. The qualitative research was carried out through focus group discussions with 10 employees. The quantitative research was conducted with 155 employees at Tan Son Nhat Operation Center – Vietnam Airlines JSC through a survey questionnaire by the convenient sampling method. The research results analyzed by partial least square – structural equation modeling (PLS – SEM) indicated that: Components of authentic leadership (AL): self-awareness (SA), internalized moral perspective (IMP), balanced processing (BP), and relational transparency (RT) have a positive impact on employee’s engagement through the mediating role of job satisfaction.</p> Nguyễn Văn Thụy Chí Vũ Đức Văn ##submission.copyrightStatement## 2022-04-11 2022-04-11 6 2 2427 2439 10.32508/stdjelm.v6i2.945 title description none g The ‘responsibility to protect’ doctrine: Reviewing the Kyrgyzstan crisis in 2010 <p>Peacekeeping and human rights protection are two significant missions of the international community nowadays. However, the world is still facing difficulty in dealing with several international crimes, such as genocide, war crimes, ethnic cleansing, and crimes against humanity. This paper introduces contents of the ‘Responsibility to protect’ doctrine, an international legal norm that has been promoted since 2005 to help prevent the abovementioned crimes by applying intervention measures; the paper also analyses, evaluates the extent of effectiveness, limitations and positives when implementing this doctrine in practice, via the case of Kyrgyzstan riots in 2010, and proposes relevant recommendations. As a result, the ‘Responsibility to react’ and ‘Responsibility to prevent’ are the two contents of the ‘Responsibility to protect’ doctrine that indicate limitations in practice. It is recommended by the paper that there is a need for clearer mechanisms and detailed procedures containing steps for evaluating and guiding the implementation of appropriate measures in relevant stages/cases; this contributes to determining when a nation cannot or is unwilling to prevent conflicts from occurring (‘Responsibility to prevent’), and also to resolve issues of political will of states and/or regional/international organizations relating to the intervention (‘Responsibility to react’).</p> Huân Tường Võ ##submission.copyrightStatement## 2022-04-12 2022-04-12 6 2 2440 2448 10.32508/stdjelm.v6i2.957 title description none g The effects of innovation on export of the small and medium-sized enterprises: The case of Viet Nam <p>Export has played an important role for firms in the context of globalization. However, firms, particularly small and medium-sized enterprises (SMEs) in developing countries, have faced many barriers to export; one of the major barriers is their less competitive products. This study aimed to examine the effects of innovation on the SMEs’ decisions to export in Vietnam. To examine this relationship, this study used the dataset from the SMEs surveys in 2011, 2013 and 2015. In addition, the probit model was used to estimate the relationship between the variables in the research model. The probit’s estimates revealed that innovation has a positive and statistically significant effect on the SMEs’ decisions to export and direct export. However, the marginal effect results showed that the effects of innovation on decisions to export and direct export were negligible. The results from this study provided policymakers and firm managers with empirical evidence on the role of innovation in promoting export. Thenceforth, this research proposed policy and managerial implications for promoting the effectiveness of innovation and export in SMEs.</p> Duc Nha Le Thanh Tien Pham ##submission.copyrightStatement## 2022-04-12 2022-04-12 6 2 2449 2462 10.32508/stdjelm.v6i2.974 title description none g Vietnam public debt forecast in the period of 2021 - 2025 <p>Vietnam's public debt has an important achievement in the years 2017-2019. Specifically, the public debt/GDP ratio was 61.4% of GDP in 2017. However, this ratio fell to 58.3% in 2018 and 55% in 2019. This improvement in public debt/GDP is due to the large scale of the economy and high economic growth rate. This fact implies there is a relationship between public debt and macroeconomic factors. Theoretical research shows that the macroeconomic factors affecting public debt include the State budget deficit, economic growth, real interest rates and exchange rates. This study will build a model to analyze the impact of those macroeconomic factors on public debt/GDP, period 2000 - 2020. The study has an important finding. That is, there exist two mechanisms, which have opposite effects on the evolution of public debt/GDP of Vietnam. Firstly, it is the trend of expanding investment to promote growth. This trend increases public debt/GDP. And second, it is the tendency to increase the real size of the economy, as measured by real GDP growth. This trend reduces public debt/GDP. The author relies on the above two trends to explain the evolution of Vietnam's public debt/GDP, period 2000 - 2020. Next, based on the analytical model, the author will forecast the trend of public debt in the period 2021 -2025. The forecast takes into account the impact of Covid-19 on public debt.</p> Vi Dinh Hoang Tuong ##submission.copyrightStatement## 2022-05-21 2022-05-21 6 2 2463 2473 10.32508/stdjelm.v6i2.848 title description none g Signal quality from retailers and repurchase intention to buy safe vegetables: The mediator role of modern retailer brand preference <p>The study focuses on examining the relationships between signal quality, brand equity and customer behavioral intention. The study was carried out with the use of a combination of qualitative research methods and quantitative research methods, in which, structural equation modelling (SEM) was used to test the theoretical model and research hypotheses. The primary data was collected through a survey of 328 customers who have bought safe vegetables at stores of Bach Hoa Xanh brand and Co.op Food brand in Ho Chi Minh City. The result shows that: (1) signal quality from the retailer has a positive effect on retailer brand preference and repurchase intention; (2) retailer brand preference is important to brand equity measured in terms of signal quality, which acts as a partial mediator in increasing repurchase intention. Besides, the research has contributed to adjusting the scale of concepts in accordance with the current research context, which can serve as a reference source for future studies; At the same time, propose some management implications towards helping modern retailers with safe vegetable business increase brand equity and sales efficiency in the direction of signaling.</p> Đinh Vũ Định Phan Thị Lý ##submission.copyrightStatement## 2022-05-21 2022-05-21 6 2 2474 2485 10.32508/stdjelm.v6i2.905 title description none g Factors affecting the financial reporting quality in Vietnamese enterprises: A perspective from Contingency Theory <p>This research aimed to identify factors that affect the financial reporting quality (FRQ) in Vietnamese enterprises, in which the affecting factors are based on the Contingency Theory. Data were collected through an email survey combined with a direct, and the survey period was from January to June 2020. We focussed on surveying CFOs, chief accountants, and accountants who had at least three years of working experience. The research sample consisted of 235 enterprises with headquarters in Ha Noi, Ho Chi Minh, and Da Nang (the three largest cities in Vietnam), in which there were 92 small enterprises, 69 medium enterprises, 74 large enterprises; 26 businesses that have adopted the international financial reporting standards (IFRS) as their accounting framework for the preparation of their financial reporting, and 109 businesses that have not applied IFRS. The research model and hypotheses have been tested by Multiple Linear Regression (MLR) with the support of SPSS statistical software. The research results indicate that there are four factors significantly affecting the FRQ: Administrator support; Accountant competency; Internal Control effectiveness and IFRS application. The study contributes to perfect FRQ’s direct method measures, highlighting the role of the Contingency Theory in creating a basic that helps to interpret the relationship of contextual factors and FRQ.</p> Pham Quoc Thuan ##submission.copyrightStatement## 2022-05-21 2022-05-21 6 2 2486 2499 10.32508/stdjelm.v6i2.907 title description none g Economic position of Vietnam in ASEAN economic community (AEC) <p>The process of Vietnam participating in ASEAN in the past 26 years (1995-2021) has shown that it has many practical contributions to this organization. In a new international and regional context, Vietnam with its new position and strength after 35 years of renovation gives it opportunities to contribute more to the solidarity and integration of ASEAN. In addition, the formation of the ASEAN Economic Community (AEC) is a chance for Vietnam to expand its development for the Southeast Asian community’s peace, cooperation, and development in the future. After 26 years of participating in this regional organization, Vietnam has made many significant contributions to turning ASEAN into a framework of peaceful cooperation for mutual development. From ASEAN-6 to ASEAN-7 and ASEAN-10, it is clear that as a responsible member, Vietnam's position and influence in this region have been increasingly recognized. Through various dialogue mechanisms, Vietnam today has become an important and comprehensive economic partner of AEC. In this study, the research team used statistical data from the World Bank, the General Statistics Office of Vietnam, the Global Competitiveness Index (GCI) of the World Economic Forum, labor productivity of the Asian Productivity Organization (APO) to clarify Vietnam's economic position in AEC. The collected data shows that Vietnam's economic position within AEC countries has increased; however, it still faces many challenges and the risk of economic backwardness. Based on that, the study proposes some solutions to enhance Vietnam's economic position in AEC.</p> Nguyen Van Luan Nguyen Anh Tuan Tran Thi Kim Dao Nguyen Thi Lai Nguyen Van Sang ##submission.copyrightStatement## 2022-05-21 2022-05-21 6 2 2500 2515 10.32508/stdjelm.v6i2.908 title description none g The impact of social media marketing on customer loyalty using telecommunications services in Vietnam <p>This paper is based on the theory of Social Media Marketing and the Stimulus Feedback Mechanism model. The research sample was surveyed from 300 customers using MobiFone telecommunication services in Khanh Hoa and Dak Lak. The specific objective is to identify the components of Social Media Marketing (SMM) and determine the extent to which those factors affect customer loyalty. The qualitative and quantitative research methods are applied to evaluate the influencing factors of SMM on the loyalty of customers using telecommunications services at MobiFone Service Company Region 7. The results showed that five factors of the SMM activities (interaction, informational, word of mouth, personalization, trending content) have a direct impact on customers' perceived value (Value Equity, Brand Equity, Relationship Equity). Besides, except for the factor of brand equity, value equity and relationship equity have impacts directly on customer loyalty. Based on the results of empirical research on the influence of SMM on the loyalty of customers who are using MobiFone telecommunications services at Company 7, some administrative policy implications are suggested to increase customer loyalty to mobile network services and also increase the impression of MobiFone brand.</p> Phan Thị Duyên Lê Chí Công Nguyễn Ngọc Duy ##submission.copyrightStatement## 2022-05-21 2022-05-21 6 2 2516 2529 10.32508/stdjelm.v6i1.916 title description none g Capital structure and operational self-sustainability of Vietnam microfinance institutions <p>This paper analyzes the impact of capital structure on the operational self-sustainability of Vietnam microfinance institutions (2006-2019). We collect data from financial reports of microfinance institutions compiled by MIX Market. Regression results with FE and System GMM models show a positive relationship between capital structure components and operational self-sustainability of Vietnam microfinance institutions (OSS). This positive relationship shows that capital structure plays a significantly important role in the operational self-sustainability of Vietnam microfinance institutions. Besides, we also find a nonlinear relationship, which shows that the main sources of financing have a positive impact on OSS with high proportions of capital structure components. In particular, equity has a significantly positive effect at both high and low ratios, while the others have weak effects. Vietnam microfinance institutions should make the maximum use of operating capital sources (especially savings and commercial loans) to increase sustainability. Although still heavily dependent on equity sources, microfinance institutions tend to focus on market capital sources (deposits, loans) in order to reduce dependence on equity. This is also the basis for us to provide some policy implications to improve the sustainability of Vietnam microfinance institutions at the end of the paper.</p> Thông Quang Trương Bình Thanh Phan Nguyễn Thanh Liêm ##submission.copyrightStatement## 2022-05-28 2022-05-28 6 2 2530 2539 10.32508/stdjelm.v6i2.922 title description none g Effects of taxation on economic growth developing countries in Southeast Asia <p>This article aims to study the impact of taxes on economic growth in developing countries in the period 2000-2019. The analysis focuses on differences between countries in tax structure, disaggregating the impact of different revenue sources on economic growth across countries. The particulae emphasis is placed on the impact of fiscal policy through tax instruments on economic growth in developing countries. The relationship is investigated by using the panel data regression analysis of 5 developing countries: Malaysia, Thailand, Vietnam, Philippines, Cambodia. The research also applies POOL, FEM, REM, FGLS models. The results of the study show that increasing tax revenue has a negative impact on economic growth in developing countries. Tax-based fiscal policies are policy tools to overcome fiscal deficits in developing countries. Tax-based fiscal policies are policy tools to overcome fiscal deficits in developing countries. However, fiscal revenues are used to finance unnecessary expenditures, which may be caused by the political system or by inefficient redistributive policies. Tax effect is not reflected in GDP growth rate. Thus, tax revenue can be a viable source of deficit correction but will reduce economic growth. On that basis, the study has proposed a number of policy implications in the administration of tax policy in Vietnam.</p> Hằng Thị Thuý Lê ##submission.copyrightStatement## 2022-05-28 2022-05-28 6 2 2540 2549 10.32508/stdjelm.v6i2.923 title description none g A study of factors influencing intention to purchase green products for individual consumer in Hanoi <p>The aim of the study is to determine the factors affecting the intention to purchase green products of individual consumer in Hanoi city. The article used a combination of qualitative research methods (in-depth interviews) with quantitative research (exploratory factor analysis and regression analysis) with a sample size of 190 observations to determine the factors. The research model identifies 5 factors that affect the intention to purchase green products, including (1) Attitude towards green behavior, (2) Social influence, (3) Environmental concerns, (4) Perceived consumer effectiveness, (5) Eco-label. The test results show that there are 4 factors that positively affect the green buying intention of consumers, including Social influence, Eco-label, Perceived consumer effectiveness, Attitude towards green behavior. In which, the Social Influence factor has the strongest impact because consumers observe referenced people (family, friends, colleagues, relatives, ...) use and media advertise a lot green products, their desire to buy green products will be higher. However, the Environmental concerns do not have an impact on the green purchase intention of consumers identified with two main reasons due to the degree of unwillingness to solve environmental problems because that is too big problem for an individual to solve and information about green products is not available. From the research results, the article has made managerial implication in establishing policies to promote the purchase intention of green products of consumers in the future.</p> Nhung Thị Hoài Dương Thu Uyên Thị Nguyễn Thanh Huy Dương ##submission.copyrightStatement## 2022-05-28 2022-05-28 6 2 2550 2562 10.32508/stdjelm.v6i2.926 title description none g Trust, organizational commitment and tacit knowledge sharing between employees in IT industry firms in Ho Chi Minh City <p>In organizations, knowledge is divided into two types: explicit and tacit knowledge. Tacit knowledge can play an important role towards company’s sustainable development and competitiveness capabilities. The crucial of tacit knowledge has been verified in relation to decision-making, time management, quality and performance in organizations. Tacit knowledge is an intangible asset and its value increases as more people share it. However, tacit knowledge sharing is not a very easy task because of its complex nature. This study aims to analyze the psychological mechanism affecting the tacit knowledge sharing (TKS) behaviour of IT employees based on psychological contract model and organizational commitment literature. Surveys were designed by structured questionnaires to collect data using convenience sampling and yielded 408 responses from IT employees working at IT industry enterprises in Ho Chi Minh City. The research hypotheses were developed and validated using structural equation modeling (SEM) approach. The results show that TKS is directly influenced partly by trust (TRU) among coworkers and three organizational commitment components such as affective, normative, and continuance commitment (AOC, COC and NOC) mediate the relationship between TRU and TKS. Based on these results, author offers some suggestions to managers in firms concerning relevant policies that enable their knowledgeable employees to share tacit knowledge.</p> Doan Bao Son ##submission.copyrightStatement## 2022-05-28 2022-05-28 6 2 2563 2576 10.32508/stdjelm.v6i2.941 title description none g Dispute settlement of cross-border mergers and acquisitions by arbitration in Viet Nam <p>Cross-border mergers and acquisitions transactions have increased dramatically around the world over the past several decades and have become one of the most important types of commercial transactions. In the process of performing cross-border mergers and acquisitions transactions, disputes will occur with certain characteristics at different stages. As a result, when a dispute occurs, the parties must use various dispute settlement methods such as negotiation, conciliation, court, arbitration. Combining the aforementioned ways is a prioritized choice for having an adequate mergers and acquisitions dispute resolution mechanism by leveraging the benefits while also eliminating the limitations of given methods. This article will analyze cross-border mergers and acquisitions disputes and some issues in dispute resolution by arbitration, such as joinder and consolidation procedure, expert participation and confidentiality in arbitration.

Forestation is one of the solutions to reduce CO2 emissions. Thus, this paper investigates the possible impact of reforestation on CO2 emissions in Vietnam during 1990-2019. Data in the study is collected from the World Bank. The study uses a Vector Auto Regression model (VAR) to analyze the relationship between reforestation and CO2 emissions. The research results show that forest coverage has a negative impact on CO2 emissions in Vietnam. On the other hand, the results also suggest that there is a two-way relationship between urbanization and CO2 emissions in Vietnam. Based on the findings, the Vietnamese government can reduce CO2 emission by increasing forest coverage, harmonizing between urbanization and economic growth toward green development and forest protection. This study is significant to the solutions of tackling climate change by providing evidence of the effects of reforestation on CO2 emissions in Vietnam.</p> Minh Quang Lê Minh Hoàng Nguyễn Hải Tòng Thị Minh ##submission.copyrightStatement## 2022-05-29 2022-05-29 6 2 2600 2610 10.32508/stdjelm.v6i2.952 title description none g Impact of financial development, trade openness, and renewable energy consumption on economic growth <p>The financial market is responsible for connecting savings and investment in order to put social resources into production and business. The developed financial market has able to generate low transaction costs along with trade policies and international integration, which can be the driving force for economic development in each country. In the context of the industrial revolution 4.0, countries must move towards cleaner production by using renewable energy sources to reduce pollution and create advantages for long-term economic growth. The research aims to assess the impact of financial development, trade openness, and the use of renewable energy on economic growth in the period from 1990 to 2020. Using the autoregressive distributional lag (ARDL) method in order to assess the short and long-term relationship, the research results suggest that there exists a positive impact of financial development on economic growth in both the short and long term. Specifically, a 1% change in financial development will change economic growth by 0.0524% in the short run and 0.0082% in the long run. The research also confirms that renewable energy use and trade openness have no impact on growth, but there can be positive effects of renewable energy use and negative effects of trade openness to economic growth in the long run.</p> Chien Nguyen ##submission.copyrightStatement## 2022-05-29 2022-05-29 6 2 2611 2621 10.32508/stdjelm.v6i2.964 title description none g Selection of tools/ criteria for measuring the level of Leanness <p>Companies have failed to implement Lean. One of the suggestions for solutions is to conduct an assessment of the current Lean application of the enterprise. Lean tools/criteria are diverse, and empirical studies which have applied one of these tools/criteria however are yet based on subjective viewpoints, which leads to a different result, and assessment results may not be accurate. The purpose of this study is to propose a lean measurement tool(s)/criterion that ensures reliability and is (are) widely recognized at an acceptable level. This study uses Scopus and Web of Science databases to synthesize data and compare it to AJG 2021 journal classification. In addition, with the research combining the citation analysis method, using the artificial intelligence analysis tool to analyze, based on this method, hopefully, the results confirm whether the selected set of assessment tools/criteria is rejected or accepted by the scientific community. Research results show that tools/criteria to evaluate leanness currently tend to be applied for manufacturing enterprises. There has been yet no specific measuring tool/criteria for service businesses, and they do not reach perfection. From the obtained results, at present, this study suggests two assessment tools/criteria: one for high-tech manufacturing enterprises; one for the other manufacturing industries.</p> Nguyen Trong Hien Ton ##submission.copyrightStatement## 2022-05-29 2022-05-29 6 2 2622 2630 10.32508/stdjelm.v6i2.969 title description none g Social capital, knowledge sharing and innovation ability for production activities of farmers households in Ben Tre province <p>Based on the results of previous studies on social capital, this study aims to propose and test a theoretical model of the relationship between social capital, knowledge sharing and innovation capacity for production activities of farmer households in Ben Tre province.

The paper analyzed the balance data of of 81 construction firms listed on the Ho Chi Minh Stock Exchanges and Ha Noi Stock Exchanges from 2013 to 2018, using Feasible Generalized Least Squares (FGLS) model. Specifically, diversity of the Board of Directors is the independent variable; and the three indicator variables are gender diversity, nationality diversity and educational diversity. The results show that the diversity of foreigners in the Board of Directors has a positive and statistically significant impact on corporate performance according to two methods of components ratio (Proportion) and degree of heterogeneity (Blau index), while the educational factor has a negative and statistically significant effect on ROA by both methods. In addition, the diversity of gender factors in the Board of Directors has a negative and statistically significant impact on ROA only with the component ratio method. This paper has contributed to the literature by providing evidence of board diversity on corporate performance. Finally, based on the research results, the authors expect that the findings would help construction firms more effectively perform on corporate governance. As the government increasingly considers board diversity policies, this study will have useful implications for Vietnamese managers.</p> Trần Thị Thùy Linh Khoa Trần ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2664 2678 10.32508/stdjelm.v6i2.843 title description none g Issuing legal documents on prevention of pandemic – From practice of prevention of Covid-19 pandemic in Vietnam <p>The outbreak of the Covid-19 pandemic has put Vietnam and the others in a situation that needs to have the policies instantly to handle the quick spread of the diseases.

Despite its validity in Vietnam since the beginning of 2017, the Convention is still applied in a very limited way by domestic businesses. In fact, there have been a lot of sophisticated legal issues in international trade, especially in cases the parties fail to promptly or properly perform their contractual obligations or even in case of non-performance. This article is aimed to study the provisions of additional time for late performance (Nachfrist) under CISG 1980 in comparison with Vietnamese laws, and current situation of extension for contract performance under CISG 1980. The research collected, summarized, compared and analyzed data from trustworthy sources and conducted the in-depth interviews with the experienced experts in commerce, law, and dispute settlement. The results point out some similarities and differences in establishing the additional time between Vietnamese legal documents and the Convention. Furthermore, it is also showed in this article that disputes related to the Nachfrist clause are quite common and tend to decrease, but only with the participation of mainly European countries and China. In terms of content of dispute cases, the rate of disputes arising from the Seller's breach of contract is much higher than that rate from the Buyer’s. Regarding methods of dispute settlement, China has nearly always chosen arbitration while European countries have given priority to the court. From the analysis, some implications for Vietnamese businesses in the application and interpretation CISG’s provisions of contract extension were represented as solutions to help businesses improve their legal knowledge and limit risks in international commercial activities.</p> Hoang Tien Nguyen Anh Nguyen Cat Nguyen Ly Nguyen Thien Tran ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2689 2700 10.32508/stdjelm.v6i2.944 title description none g The impact of university brand image on students’ loyalty: A study of non state universities in Ho Chi Minh City <p>In the integration with the world economy, a large number of universities are gradually increasing, leading to strong competition. Therefore, building and managing a university brand is one of the key strategic solutions to enhance students’ loyalty towards the university. This paper applied brand equity theory and customer-based brand equity (CBBE) models to assume the impact of brand image on students’ loyalty. PLS-SEM was employed for data analysis by Smart- PLS 3 software with 431 respondents (second-year to fourth-year students of non-public universities in Ho Chi Minh City). Research results identified 4 dimensions of university brand image: university heritage, trust, service quality and appearance &amp; atmosphere. The finding revealed that the dimensions of university brand image had a positive impact on university reputation and students’ satisfaction, influencing students’ loyalty. Furthermore, university reputation was also a mediator to moderate the relationship between university brand image and students’ satisfaction. Consequently, managerial implications considered branding and brand image management as a necessary strategy that universities should conduct to attract students, differentiate and create competitive advantages.</p> Hoa Thai Nguyen Le Đan Ngọc Sỹ Nguyễn ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2701 2715 10.32508/stdjelm.v6i2.958 title description none g The assessment of impacts of public investment, state investment on private investment and economic growth in Vietnam <p>The study aims to assess the impact of public investment and state investment on private investment and economic growth in Vietnam. The study applies the regression model with standard error of Driscoll &amp; Kraay with panel data for 22 economic sectors of Vietnam in the period 1990-2019. The results show that public investment and state investment have a positive impact not only on private investment but also on industry GDP, thereby promoting economic growth. It is also important to pay attention to the industry factor in the process of public investment and state investment. Although the processing and manufacturing industry has the highest GDP and number of enterprises compared to those of other sectors, the impact of private investment and state investment on GDP growth is not necessarily the most considerable. Other industries such as Agriculture, Wholesale and retail; repair of automobiles, motorcycles, motorbikes and other motor vehicles, Accommodation and catering services, State management, national security; compulsory social guarantees; The Arts, Play and Entertainment sectors have a better impact on growth. It was the intervention of the state through state-owned enterprises that created the transformation. Therefore, the importance and directional role of state investment cannot be denied. Finally, private investment has a better impact on sectoral GDP growth than state investment. This demonstrates the dynamic role of the private sector as a driver of the economy.</p> Thuy Lien Thi Nguyen ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2716 2726 10.32508/stdjelm.v6i2.959 title description none g Assessing state management of the environment in Thanh Sơn district, Phu Tho province <p>Nowadays, environmental protection has been an urgent topic of interest to society. Along with the strong growth of the global economy, the sources of harm to the environment are increasing significantly. This not only puts pressure on urban areas but also has a great influence on rural areas Vietnam. Thanh Son is mainly an agricultural district where the rural areas account for over 90% of the natural areas and over 80% of the district's population living (in 2019). The environmental protection, garbage collection, transportation and treatment of domestic wastes to ensure environmental sanitation in particular are paid more attention and monitored by the District Party Committee and People's Council, which is the main target in socio-economic development and in the Resolution of the district Party Congress. However, the process of socio-economic development has posed many challenging problems, including serious environmental pollution in rural areas. Domestic wastes from plantation and animal husbandry activities of households have not been thoroughly treated. In addition, planning and state management activities are still limited as communes do not have places to collect and treat wastewater and other kinds of wastes, etc. Some communes in the district have difficult terrain to travel, and the system of branch roads has not been developed.

Leverage is measured by the ratio of long-term debt to the total book value of equity. Earnings management is measured by using accrual-based measures (AEM) and real earnings management measures (REM). Data comprises 45 manufacturing companies on Vietnam stock markets (HNX and HOSE) that have increasing or high leverage in the period 2017-2019, forming 135 observations. Multiple regression analysis with panel data is used to estimate the impact of leverage on earnings management. Results research show that firm leverage has a positive effect on earnings management using accrual-based measures (AEM) and has a negative effect on earnings management using real earnings management (REM) measures but with no statistical significance. Results research suggest that leverage changes and leverage levels may have differing impacts on earnings management based on AEM and REM. Additionally, the research finds that firm performance (ROA) is associated with positive earnings management, and firm size (SIZE) is associated with negative earnings management.</p> Diem Thi Hong Tran ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2739 2751 10.32508/stdjelm.v6i2.963 title description none g Factors affecting the willingness to accept digital transformation by small and medium enterprises in Ho Chi Minh City <p>Digital transformation is becoming a strategy at businesses and organizations in the 4th Industrial Revolution. The 2020 report by Cisco &amp; IDC on digital maturity of small and medium-sized businesses in 14 countries in the Asia-Pacific region shows that: 31% of businesses are in the early stages of digital transformation, down 8% compared to 2019; 53% are in the observation period - a 3% increase compared to 2019; 13% are in the challenging stage, and 3% of the businesses have entered the mature stage, an increase of 4% and 1% respectively from 2019. Digital transformation is an irreversible trend; if a business do not keep up with it, they will inevitably fail, especially small and medium enterprises in Vietnam.The study analyzes the factors affecting the willingness to accept of Digital Transformation by small and medium enterprises (SMEs) in Ho Chi Minh City. For research, the author collects data from a direct survey of 290 SMEs in Ho Chi Minh City. The research results show that there are 8 independent factors affecting the adoption of Digital Transformation by enterprises: (1) Perceived relative advantage, (2) Perceived compatibility, (3) Perceived complexity, (4) Knowledge of digital transformation, (5) Management awareness of digital transformation, (6) External change agents, (7) Pressure from partners and opponents.

The data for the study was extracted from the dataset of the results of the Vietnam Living Standards Survey 2018 (VHLSS 2018). After the data was connected, filtered, and cleaned, 34,448 observations were qualified. To overcome endogenous difficulties in the model, the estimation of linear Engel equations using instrumental variable regression was conducted. The findings of the study reveal that as household size increases, average food expenditure reduces, supporting the food paradox that exists in the Vietnamese food market. The positive relationship between income per capita and average expenditure on food is also confirmed in the OLS model. Research shows that households with the head being married, educated, employed (especially self-employed) have a higher average expenditure on food than those in other household groups. The average food cost per household rises in households with a high number of children and the elderly. The findings of this study will assist food companies in forecasting market demand, allowing them to develop effective business strategies and production plans. It also aids policymakers in forecasting food demand so that proper national food security policies can be implemented.</p> LÊ THỊ TUYẾT THANH HUỲNH THỦY TIÊN ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2763 2773 10.32508/stdjelm.v6i2.984 title description none g Effects of exports on the growth of small and medium enterprises – empirical evidence from Vietnam <p>The paper aims to examine the impact of exports on the growth of Vietnamese manufacturing small and medium-sized enterprises (SMEs) by exploring the information of 36,486 enterprises across 24 manufacturing sectors from the Vietnam Annual Enterprise Survey (VAES) in the period 2014-2019. To deal with the problem of variable variance, autocorrelation, and endogeneity of the model, the paper uses the Pooled Ordinary Least Squares (POLS) regression method with a strong standard error method and system Generalized Method of Moments (GMM). Export participation by SMEs is positively associated with business growth in terms of sales and employee, according to the findings. Moreover, the positive impact of exporting on firm growth is greater among permanent exporters than among new exporters. The relationship between exporting and employment growth is negative among firms that exit international activities. The study's findings indicate the need of adopting policies that promote SMEs in transition economies like Vietnam to engage in exporting activities. Furthermore, the findings show that financial assistance and suitable ownership would enable SMEs to take advantage of export opportunities to increase sales and employees.</p> Ngân Thị Thanh Lê ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2774 2786 10.32508/stdjelm.v6i2.989 title description none g Facebook effects on envy, depression, and impulse buying toward university students in Ho Chi Minh City <p>This study combines the theoretical framework of social ranking and envy, depression and impulse purchase behavior of Facebook users. The purpose of the study is to determine the relationship between Facebook, envy, depression and impulsive buying. With the combination of quantitative and qualitative methods conducted with 380 observed samples who are university students in Ho Chi Minh City frequently browsing Facebook, research results show that regular use of Facebook causes envy and depression. To alleviate this negative psychology, students tend to buy impulsively, though this behavior causes financial and mental harm to the young buyers. The study applies basic linking to online interactions, especially on Facebook. College students spend a large amount of time on online activities, especially accessing Facebook. Research results show that despite the pleasure given by using Facebook, the platform’s users will suffer from depression caused by long hours spent. If college students are aware of the potential dangers of overusing their time on Facebook, they can limit their use or become more aware of negative feelings generated by envy about others' personal information. Successfully avoiding depression requires college students to retain a positive perception and keep an optimistic attitude.</p> Trần Văn Đạt ##submission.copyrightStatement## 2022-06-18 2022-06-18 6 2 2787 2799 10.32508/stdjelm.v6i2.994 title description none g Factors affecting dividend payment policy: Differences between consumer goods and consumer staples in Vietnam <p>The factors affecting the dividend distribution policy of companies listed on the Ho Chi Minh Stock Exchange are investigated using the signal theory and agency cost theory (HOSE). To generate empirical evidence, the study collects data from publicly traded and dividend-paying consumer companies over a 12-year period (2009-2020). At the same time, in order to better understand the research problem, the study examines the variations in factors affecting the dividend payment policies of two kinds of consumer companies (consumer staples and consumer discretionary). The findings of the FGLS regression analysis demonstrate that the following factors always affect dividend payment policy, consumer services, and consumer goods companies: earnings per share, debt-to-equity ratio, form of cash, and stock dividend payment. Consumer staples and consumer discretionary corporations' dividend policies are influenced by distinct factors. Consumer products companies have a greater dividend payout ratio than that consumer service companies.

This paper analyzes some indicators affecting the level of GDP per capita, including average labor productivity, the percentage of trained workers of working age, the unemployment rate of the labor force in working age, the increase in the level of investment per capita in the whole society. With the application of the Bayesian linear regression analysis method, the analysis results show that the factor of the unemployment rate of the labor force in working age has the highest impact on GDP per capita. The factor of the percentage of trained workers of working age has the second highest impact, and the factor with the least impact in this study is Labor productivity. Except for the factor of the unemployment rate of the labor force in working age, which has a negative impact on GDP per capita, other factors show a positive impact on GDP per capita. The analysis results also suggest that besides maintaining the low unemployment rate, the government needs to pay attention to raising the proportion of trained workers by improving policies and investing more in education and training, thereby improving labor productivity and leading to an improvement in people's living standards.</p> Trần Quang Cảnh Phan Thị Đông Hoài ##submission.copyrightStatement## 2022-06-20 2022-06-20 6 2 press press 10.32508/stdjelm.v6i2.961 title description none g Testing Okun's law on the relationship between employment rate and economic growth in developed and developing countriesa <p>Regression models for panel data are increasingly widely used in socio-economic studies because they consider the relationship between many objects over time; thus they can better measure unobservable effects. This study aims to test Okun's law on the relationship between economic growth rate and unemployment rate in two groups of countries (developed and developing). The study was conducted on panel data for the period 2008–2019 using a number of static and dynamic regression models. The model test results show that the dynamic regression model (differential general moment model, DGMM) is a more suitable model in testing the validity of Okun's law for these two groups of countries. These results show that the relationship between unemployment and economic growth in both these groups of countries is quite consistent with Okun's law, in which developing countries have a higher degree of concordance. Moreover, the group of developing countries has a larger Okun coefficient, so economic growth in this group of countries is more affected by the unemployment rate. From the obtained results, we try to explain the causes leading to this difference in this influence level , and suggest some solutions that need special attention to achieve the goal of economic growth.</p> Vo Thi Le Uyen Lê Thị Xoan ##submission.copyrightStatement## 2022-06-20 2022-06-20 6 2 press press 10.32508/stdjelm.v6i2.865 title description none g Propose a smart classroom model to enhance education experience in industrial revolution 4.0 era <p>Industry 4.0 has changed many areas of life, among which education is one of the fields with the most impact.

Research results show that the Covid-19 pandemic does not seem to affect Vietnam's export value compared to the same period last year. Through this result, it also shows that the Government of Vietnam has taken good export strategy to deal with the pandemic and bring high export value. The results of applying SARIMA model show that the model has a predictive value that approximates the actual export value with high accuracy in the period from January 2000 to May 2021. From testing the forecast accuracy of the SARIMA model, the study also makes forecasts about Vietnam's export value from 06/2021 to the end of 2021.
