Applying the Unified Theory of Acceptance and Use of Technology (UTAUT) in Investigating Online Impulsive Buying Behavior of Vietnamese Consumers

Based on The Theory of Adoption and Use of Technology (UTAUT) (Venkatesh et al., 2003), this study builds a research model regarding the Factors affecting Vietnamese consumers' online impulsive buying behavior. The multiple regression results reveal that Performance Expectancy, Effort Expectancy, Social Influence, and Online Buying Intention play a crucial role in amplifying the development of online impulsive buying behavior in Vietnam.

Returns to Education and the Demand for Labour in Vietnam. ESRI WP506. July 2015

Using data from the Vietnam Household Living Standards Survey, this paper examines the returns to education in Vietnam in 2002 and 2010, and how these returns changed over time. Given the economic growth that took place during this time period, the relative demand for labour is also assessed in order to identify if skill-biased technical change played a role in explaining the returns to education in Vietnam at a time of exceptional economic growth. The male and female education returns displayed a linear pattern in both 2002 and 2010, with earnings rising with increased levels of education. Relative to males with no qualifications, the returns to those with a vocational training qualification or below fell between 2002 and 2010, while the economic returns to a college education and above increased. Similar results were observed for females. In relation to relative labour demand, the results indicated that the demand for all levels of education (apart from males with a high school qualification) relative to those with no qualifications grew between 2002 and 2010. However, there was particularly strong growth in the demand for those with a vocational training qualification and above, especially an advanced degree qualification. Findings from the paper show that high levels of economic growth in Vietnam between 2002 and 2010 have facilitated increasing returns to education and demand for high skilled labour. In addition, there appears to be shortages for some types of skilled labour

Factors Influencing Adoption of Online Payment via E-Commerce Platforms

In this study, the research group applied the Technology Acceptance Model (TAM) by Davis (1989) to analyze factors influencing customers’ intention to use the online payment via e-commerce platforms as well as to encourage Vietnamese consumers to adapt this means of payment. Besides Perceived Ease of Use and Perceived Usefulness in the original model of Davis (1989), three additional dependent factors (Subjective Norm, Trust, Risk) were added to the model. The new model proposed by the research group aims to give a more well-rounded explanation on Vietnamese consumers’ attitude and intention towards the online payment. Using sample data including 448 consumers in the Northern region of Vietnam, the research group has been able to validate the hypothesis model and prove that independent and dependent variables (Attitude towards Use and Intention to Use) are positively correlated. Among the 5 dependent variables, Subjective Norm is found to be the most significant factor contributing to promote online payment attitude and intention through e-commerce websites of Vietnamese consumers.

SOLUTIONS TO ENHANCE THE COMPETITIVE ADVANTAGE OF SMALL AND MEDIUM ENTERPRISES IN THE CONTEXT OF POST-COVID-19 PANDEMIC IN TRA VINH PROVINCE, VIETNAM

The purpose of this research is to find solutions to enhance the competitiveness of small and medium-sized enterprises in the context of the Post-Covid-19 pandemic in Tra Vinh Province, Vietnam, by collecting secondary data from reports from Tra Vinh Provincial People’s Committee, Tra Vinh Department of Planning and Investment, and Tra Vinh Provincial Statistics Office in the period 2016-2020. The authors used descriptive statistics, synthesis, analysis, evaluation, and expert surveys to verify former hypotheses about small and medium-sized enterprises and search for feasible solutions to enhance the competitiveness of small and mediumsized enterprises in Tra Vinh Province. The study analyzed the situation of small and mediumsized enterprises during the period 2016–2019 regarding the actual operation status, advantages, and limitations in the competition of Small and Medium Enterprises in Tra Vinh, Vietnam. From the research findings, the study proposes solutions to improve competitive advantages for Small and Medium Enterprises in Tra Vinh in the post-Covid-19 pandemic future

MACRO-ZOOPLANKTON ABUNDANCE IN RELATION TO METAL ACCUMULATION AND WATER QUALITY IN TRUC BACH LAKE

Urban lake pollution is one of the serious issues due to suffering of waste discharged from householders. However, there is a gap of knowledge about the diversity of zooplankton species and how metals accumulate in zooplankton in urban ecosystems. We addressed this by determining the rule of blooming macro-zooplankton in Truc Bach lake and levels of two essential metals: copper (Cu), and zinc (Zn) and of three non-essential metals: arsenic (As), and lead (Pb) in water samples were determined. The results showed that Cladocerans and copepods are macro-zooplankton dominant species in Truc Bach Lake. Water temperature significantly affects the variety of copepod blooming. Arsenic concentration in water collected from the lake exceeded the safety level of current Vietnamese regulation. As concentration in macro-zooplankton positively correlated with metal concentrations in the water (p 0.05) while the concentration of Cu, Zn, and Pb in water has no significant correlation with the metal in zooplankton’s body. The relative abundance of adult copepods in Truc Bach lake had a negative correlation with As concentration in water (p = 0.01). The higher As concentration in water, the lower relative abundance of copepods was found in the sample

A Study on Environmental Costs in Coal Mining Production in Vietnam

This study is conducted to identify and present environmental costs of mining production in the context of sustainable development (SD) and a lifecycle of coal mining firms. This aim is accompanied by two research questions as (i) What are the environmental costs of mining production in theory and practice in a lifecycle of coal mining firms?; and (ii) What are the key determinants of environmental costs of coal mining production in a lifecycle of coal mining firms? In order to achieve this aim, the process of coal mining production is described from the long-term perspective including projecting, building, operating and liquidation stage of a coal mine. On the basis of process analysis the identification of environmental costs is conducted in a model approach. Environmental costs of mining production are analyzed using international case studies and theoretical and practical assumptions regarding environmental costs management in mining production are formulated. The results show that the environmental costs of mining production are varied in the lifecycle of a coal mine and that they also depend on the geographical location of mining firms. Environmental costs of mining production have to be predicted in a long-term perspective including also post-liquidation costs together with taking into account the sources of their covering and models of financing.

Coordination and health sector adaptation to climate change in the Vietnamese Mekong Delta

This research examines the impact of three coordination dimensions on health sector adaptation to climate change in the Vietnamese Mekong Delta: cross-scale, cross-sectoral, and cross-boundary. While tasks are divided up between government ministries and departments in Vietnam, there is little collaboration on issues that span mandates. Similarly, while water flows in the Vietnamese Mekong Delta take resource management and health concerns across provincial boundaries, formal mechanisms for interprovincial collaboration are lacking. While decentralization efforts have sought to devolve authority and decision making to lower levels, there is continued state-centered top-down policy making, and this limits collaborative coordination across scales. All three of these issues inhibit health sector adaptation to climate change in the Vietnamese Mekong Delta, and though these coordination issues are recognized by the Vietnamese government, to date there has been little success in addressing them. The authors hope to stimulate further debate and discussion of coordination problems, and conclude that despite some significant challenges, the South West Steering Committee could play a facilitating role coordinating climate change responses in health and other sectors across the Vietnamese Mekong Delta. As an analysis of governance, this research is applicable to other areas and sectors in Vietnam, as well as to other parts of South East Asia
