Previous research has found that industry concentration and firm efficiency affect stock returns. However, it is not clear if concentration is a byproduct of efficiency and hence its effect on stock returns is driven by efficiency. This paper aims to examine the relationships between industry concentration, firm efficiency and average stock returns. Mainly, it aims to answer if the effects of industry concentration and firm efficiency on stock returns are independent and significant.

The stochastic frontier approach is used to estimate firm efficiency. The Herfindahl index is used to measure industry concentration. Regression and vector autoregressive analyses are performed to examine cross-sectional and lagged relationships between concentration, efficiency, profitability and stock returns. The characteristics-based benchmark approach is also used to investigate performance of test portfolios.

Industry concentration and firm efficiency have independent and significant effects on average stock returns through profit margins and market shares, which are related to firms’ profitability. Industry concentration has a greater positive impact on market shares than on profit margins, whereas firm efficiency has a greater positive impact on profit margins than on market shares. In sum, highly efficient firms in highly concentrated markets have lower distress risks and hence provide lower average stock returns.

The paper shows the linkages between industry concentration, firm efficiency, profitability and stock returns that have not been documented together in prior studies. Businesses can better understand the impact of concentration and efficiency on market shares and profit margins. Researchers may consider incorporating concentration and efficiency, both of which are meaningful microeconomic variables, into an asset pricing model. Investors can enhance their returns by having a zero-cost portfolio with long and short positions in stocks of firms with different levels of concentration and efficiency.

The COVID-19 lockdown has forced many organizations and employees to work from home. In such uncertain and unprecedented context, it is crucial for organizations to stimulate their employees’ creativity to adapt to new working environment and thus to sustain and improve organizational performance. This paper aims to examine how to stimulate employees’ creativity by focusing on their online knowledge sharing (OKS) behaviors, their use of online platforms and their organizations’ innovation climate in a working from home (WFH) context because of the lockdown. For empirical analysis, this research uses data from Vietnam – a developing country in the Southeast Asia.

Data are collected from employees working in Ho Chi Minh City but WFH during the COVID-19 lockdown. Structural equation models are used for analyzing the data.

Online platform use and organizational innovation climate are positively associated with creativity directly and indirectly via the mediating roles of internal and external OKS.

This research provides policymakers, organizational leaders and managers with an important evidence on how to stimulate creativity by emphasizing the roles of knowledge sharing, online platforms and innovation climate. Accordingly, relevant practical implications are also drawn to sustain or improve organizational performance in the context of WFH context because of COVID-19 lockdown. This research also contributes to knowledge management literature by providing an evidence on the relationships between online platform use, organizational innovation climate, OKS and creativity.

This research is among the early attempts that explore the associations between employees’ use of online platforms, their organizations’ innovation climate, their internal and external OKS behaviors and their creativity in the context of WFH because of a lockdown.

The purpose of this paper is to investigate the development of Viet Nam’s approach to higher education quality assurance during the past dozen years since its establishment, focusing on the achievements and challenges.

This is a desktop analysis study. The paper analyses the policies and practices related to the development of Viet Nam’s higher education accreditation system by reviewing associated literature.

The research has found out that there are several achievements, including: the development of the accreditation framework; establishment of accrediting agencies; completion of almost universities’ self-assessment reports; implementation of external assessment exercise at some institutions, a few of which were awarded accreditation certificates. However, there remain a number of challenges related to the independence of the accrediting agencies, human resources, accreditation standards and criteria, institutions’ awareness about accreditation and the pace of accreditation implementation.

The primary limitation of this study is the research methodology which merely relies on document analysis. It would be more credible if the findings could be triangulated with data taken from other sources such as interviews with key stakeholders.

On the basis of the analysis of achievements and challenges at both macro and micro levels, discussion and recommendations are made for future policy-making and management in the field of higher education accreditation.

This study aims to identify the level of political participation of local citizen in 208 districts representing for 63 provinces and cities in Vietnam and consider the effects of candidate's attributes, local political contextual factors and other local citizen’s demographic characteristics on the elections of local leaders in Vietnam.

By using Probit model and data about provincial governance and public administration performance index and self-survey about local leaders in the districts, this paper shows the different effects of candidates’ attributes, local political context and other local citizen’s characteristics on the first and second elections of local leaders in Vietnam.

The result indicates the probability of candidates being elected in the first term depends on their characteristics, local political context and local citizen. However, the reelection of local leaders for a second term depends much on their characteristics and local political context not on demographic characteristics of local citizen. The satisfaction rate of local citizen and being an incumbent for the first term are driving forces for the local citizen to elect their leader for the second term. Meanwhile, local political context such as local transparency, local official development assistance project and citizen satisfaction will increase the likelihood of local leaders being elected for the first and second terms.

The major limitation of this study is the data of the self-survey because it only provides basic but not complete characteristics of candidates and local contexts in some typical districts in 63 provinces and cities across the country.

This paper includes policy implications for candidates who want to be elected for both terms and local governance in Vietnam. The government needs to focus on building human resources for local administration to meet the requirements of building a clean, strong, modern and anticorruption administrative system.

This paper extends the analysis on examining the characteristics of candidates and local citizen as well as local political context influencing the elections of local leaders, getting involved in the Vietnam context, still underresearched, especially with reference to political participation of local citizen.

Whilst research on corporate social responsibility (CSR) is reaching new territories, the extent to which such literature manifests itself in developing countries is yet to be fully understood. To that end, this study aims to investigate the understanding, evolution and practice of CSR in Vietnam.

A systematic review of the current literature in the recent past (2000–2020) has been embraced in this research. By analysing a total of 143 articles, the authors demonstrate that there has been visible growth in published articles related to CSR in Vietnam over the past 21 years.

The authors demonstrate that CSR research in Vietnam has significantly grown in the recent past. The results highlight the in-depth distribution of publications by year, journal, industry, nature and focus of CSR research in the country.

This study is not only the first to provide an enhanced overview of the current state of CSR knowledge in the country but also sets out directions within the CSR research agenda related to Vietnam and potentially other emerging and developing countries.

This study aims to investigate the factors that influence the sustainable online purchase intentions of consumers during the COVID-19 pandemic. This study also examines the role of relational benefit and site commitment in the study model.

Data were obtained from a survey of 356 Bangladeshi consumers who were voluntarily using the internet during the COVID-19 pandemic. Data were analyzed using partial least square structural equation modelling with Smart PLS 3.0 and SPSS V25 tools.

The results show a positive and significant relationship between consumers’ personal innovativeness and impulse purchase orientation with their relational benefit and site commitment, social influence with relational benefit, relational benefit with site commitment, site commitment with the intention to purchase. Moreover, the study found that relational benefit mediates the relationship between impulse purchase orientation and social influence with site commitment. The results also indicate that site commitment mediates the relationship between personal innovativeness and impulse purchase orientation with the intention to purchase. The results further indicate that site commitment mediates the relationship between relational benefit and intention to purchase.

The findings allow online stores to consider crucial factors in their policies when making strategic decisions regarding the factors impacting consumers’ online purchasing intention during the COVID-19 pandemic.

In this study, a research framework is developed with a focus on the sustainable consumer intention to purchase. This study, therefore, adds to the existing literature by analyzing the factors that determine online purchase intentions during the COVID-19 pandemic in Bangladesh, given the limited number of studies on the online consumer behavioral intentions in related circumstances to COVID-19.

The use of the software package mini‐micro CDS/ISIS for the creation of the “Myco Database” is discussed. The design, development of the database and sorting of records are described step by step. Details of the print format and sample printout of the printed version of the directory are given.

Vietnam’s 11th National Party Congress prioritised integration, modernisation and industrialisation as the new key orientations for Vietnam. It outlined Vietnam’s integration with the world, not only economically, but also in terms of the social, cultural, educational, scientific and technological areas that can support social and economic development and sustainability. Vocational education has been recognised as pivotal to the nation’s sustainable workforce development and transformational changes. The purpose of this paper is to analyse how foreign approaches and practices have been filtered and appropriated to bring about sustainable development and transformational changes for Vietnamese vocational education.

The paper is derived from a study that involves documentary analysis, observation and semi-structured interviews with vocational learners and staff across three different vocational education and training (VET) sites in Vietnam. The overall study includes three vocational education providers and 22 participants altogether, but this paper involves observation and semi-structured interviews with eight participants, including one leader, two teachers and five students. It focusses on a Germany-funded vocational college in the northern central area of Vietnam that came under the management of the Ministry of Labour, Invalids and Social Affairs, and the local province where the college located.

The findings of the study show a critical need to develop a new “Vietnamese VET pedagogy” that filters international influences and flexibly and creatively combines them with the existing local pedagogy. To meet the local and global demands and bring transnational changes for Vietnamese vocational education, new VET pedagogies need to align with both Vietnamese historical and political situations, especially the emergent demands of the open market socialist economy and to capitalise on international influences – Confucian, French, Soviet and Western. Such a balance will ensure Vietnam makes use of both international forces and local strengths for sustainable development and transformational changes rather than passive dependence on foreign practices.

The research provides valuable insights into the appropriation of foreign practices and principles in Vietnamese vocational education. However, it focusses only on three vocational education sites in central Vietnam. Further studies with larger scale of participants and across a variety of vocational education settings including public and private institutions, community centres and family workshops will offer broader findings related to this important topic.

The study suggests practical implications for institutions to deal with the challenges associated with the adaptation of international forces into the vocational education context in Vietnam. It outlines the transformational changes in pedagogical practices related to the increased requirement to move from the traditional didactic teaching to more self-directed learning, to meet the requirements of a modern vocational education system.

This study provides unique insights into the practices and challenges of filtering foreign VET practices and principles to bring about transformational changes in Vietnamese vocational education. It, therefore, responds to the paucity of literature in this area. In addition, it examines internationalisation in Vietnamese VET, an under-researched area in the field of internationalisation of education as most of the literature in this field concentrates on the higher education sector.

The purpose of this paper is to estimate a recent trend in climate change and its impact on livelihood of community living in Nam Dinh province, Vietnam. Further, it aims to increase the government attention for adaptation measures by providing awareness of climate change and its negative impacts on livelihood.

For study purpose, cross-sectional and secondary data sets were used. The community perceptions about climate change were recorded by face-to-face interviews of 500 respondents from Nam Dinh province, Vietnam in April 2015 by using a well-structured questionnaire, whereas secondary data were collected from the statistical yearbook of General Statistics Office of Vietnam. To accomplish the study objectives, Cobb–Douglas production function and Likert scale were used to estimate the community perceptions of climate change and impact of climate change on livelihood, respectively.

Results depict that climate change negatively impacted on the productivity of rice and livestock. Particularly, frequently occurring of droughts, floods and salinity intrusion negatively impacted on rice productivity, while livestock productivity is decreased by frequent occurring of flood storms in study area.

The study results suggest a government support is essential to achieve sustainable livelihoods for coastal communities living in the Red River Delta, particularly some adaptation measures in the context of climate change are required in study area.

This study focuses on Vietnamese international students who returned from their overseas doctoral education to home universities in Vietnam (henceforth Vietnamese overseas-trained returnees). The purpose is to explore the experience of these returnees “doing research” (i.e. being research active) when resuming a lecturing role at a Vietnamese regional university. In the context of research now receiving heightened attention in both the wider global higher education (HE) discourse and the Vietnamese HE sector, this study is timely and provides valuable insights.

In total, 76 Vietnamese overseas-trained returnees from varied disciplinary backgrounds completed a questionnaire on their research motivation and their perceived constraints doing research. Eighteen subsequently took part in semi-structured interviews. The study draws on the notion of human agency from the sociocultural perspective to understand the coping strategies of the Vietnamese overseas-educated returnees in response to the challenges they encountered.

The results show that the returnees' motivations to conduct research varied, fuelled by passion, but constrained by multiple factors. Time constraints, heavy teaching loads, familial roles and lack of specialized equipment are key inhibiting factors in re-engaging in research for these returnees. Addressing them necessitated a great deal of readaptation, renegotiation and agentive resilience on the part of the returnees in employing different coping strategies to pursue research.

The paper argues for a subtle understanding of the returnees' experience of re-engaging in research that is both complex and contextual. Implications are drawn for research development in the regional Vietnamese HE context and perhaps in other similar settings.

There is little empirical knowledge about how Vietnamese returned graduates – university lecturers – continue doing research after their return. Also underexplored in global discourse is research on foreign-educated returnees doing research, while they are an important source of human resources. The present study, therefore, fills these research gaps.
