The study aims to investigate factors affecting enterprise's satisfaction and loyalty toward the Social Security's online public services, looking at the case of Thanh Hoa province, Vietnam. This study employs samples with 216 enterprises that use online public system of Thanh Hoa province's Social Security. The research model is closely linked to the SERVQUAL model developed by Parasuraman, Zeithaml and Berry (1988). We propose 23 scales that constitute the quality of service, three scales that constitute Customer Satisfaction and three components that constitute Customer Loyalty. This study use the tool of Exploratory Factor Analysis (EFA), Cronbach's Alpha test, Confirm Factor Analysis (CFA) and Structural Equation Modeling (SEM) in order to address the question of satisfaction and loyalty. The result shows that the factor with the most impact is Reliability, next is Capacity of staffs, Tangibles, Attitude of staffs, and the least impacting factor is Empathy; moreover, the results also show that Satisfaction has a strong impact on Customer Loyalty. The findings of this study suggest that Thanh Hoa province's Social Security should: (i) strengthen the reliability of online service system; (ii) build capacity for staffs; (iii) develop the responsiveness of electronic transactions systems; and (iv) improve the empathy of staffs.

The main objective of this study is to examine the interactive effect of technology spillover channels on business efficiency within the case study of manufacturing industry of Vietnam during the period from 2012 to 2018. The research model was developed with business efficiency as dependent variable and the relevant factors affecting the technology spillover capacity as independent variables. With a sample of 2,776 cross-sectional enterprises, panel data analysis approach was adopted to estimate the impact of technology spillover issue. Different spillover channels were also included in the analysis to enhance the empirical result. The study reveals that technology spillovers positively influence manufacturing business efficiency, in which horizontal spillover channel produces negative impact and vertical spillover channel, creates positive impact. Several factors that negatively affect the technology spillover capacity of businesses could be mentioned such as limited skills and experiences of workers, methods of implementing R&D, and the existence of FDI enterprises. Meanwhile, the rise of other factors related to joint-venture activities can help to increase the technology spillover capacity of businesses. In addition, skill and experience transfer makes a partial impact since this variable only positively affect the vertical spillover channel and provide no evidence of impact regarding horizontal spillover channel model.

Thi Mai Huong DOAN,Minh Thuy DO,Thanh Lan MAI,Vu Phuong Anh DO,Thi Loan NGUYEN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.12

Currently, small and medium-sized enterprises (SMEs) are accounting for about 98% of the total number of enterprises in Vietnam. Each year, SMEs create over one million new jobs, utilize up to 51% of the labor force in the society, and contribute more than 40% of GDP to the country. The study aims to analyze factors affecting the management competency of directors in small and medium enterprises in Vietnam. To achieve these research objectives, quantitative and qualitative methods were used concurrently. 300 questionnaires were sent out, but only 276 were collected and used for the quantitative analysis through SPSS 20.0 software. Cronbach’s Alpha, EFA, and regression were used to further confirm the research findings. The research findings show that all four proposed factors have impacts on the management competency of SME directors, among which enterprise features and specific policies for entrepreneur development in the locality have the strongest impacts, followed by personal features and business environment. The findings of this study suggest that managers need to focus on factors affecting the management competency of directors. This paper also provides new insight into the management competency of directors. Based on the findings, some recommendations are given for SMEs to improve management competency.

Aluminium (Al) is one of the major elements in rocks and its concentration can be varied, depending on different rock types as well as sources. The present study aimed to propose an analytical method based on the UV-Vis as a cheap, simple, and common instrument equipped in most laboratories for Al quantification in rocks after the microwave assisted acid digestion. The aluminone and 8-hydroxyquinoline were investigated for the colorimetric assay. The results show that the 8-hydroxyquinoline reagent was more favorable in terms of the minimized affects of the potential interferences present in the digested solutions, i.e., Fe3+, Si4+ and F–. The calibration curve was constructed from 0.10 mg/L to 3.00 mg/L with the goodness of linearity (R2 = 0.9996). The limits of detection and quantification (LOD and LOQ) were estimated, i.e., 0.029 mg/L and 0.087 mg/L, respectively. The 8-hydroxyquinoline was applied to real rock samples, demonstrating favorable precision (RSD = 0.34 %-1.8 %) and no remarkable differences were found compared to the inductively coupled plasma-mass spectrometry (ICP-MS) as a reference measurement approach.

The Impact of Capital Structure on Firm’s Profitability: A Case Study of the Rubber Industry in Vietnam

Huong Thi Thanh CO,Trang Thi Mai UONG,Cong Van NGUYEN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.7

This study aims to examine and measure the impact of capital structure on the profitability of companies in emerging markets. The research sample includes eighteen rubber companies listed on the Vietnam stock exchange from 2015–2019. After collecting the research data, it was imported into excel to calculate the criteria for the research model. By using Stata 16 software, the study selected a data processing model and evaluated the relevance of the regression analysis model. The research results show that the profitability of listed rubber companies in Vietnam (measured by return on equity (ROE) has a positive relationship with the debt-to-asset ratio but has a negative relationship with the long-term debt-to-asset ratio. The results also show a positive impact of firm size and revenue growth on profitability while liquidity and the ratio of tangible fixed assets to total assets do not affect significantly. These results are consistent with most of the previously published studies. However, in contrast to many previous studies, our study shows that the long-term debt-to-assets ratio has a negative effect on profitability while the debt-to-asset ratio has a positive effect. This is entirely consistent with the characteristics of long-term debt use in emerging markets.

The Effects of Trade Openness on CO2 Emissions in Vietnam

Le Thi Thanh Mai,Taegi Kim,Le Hoang Anh 한국무역연구원 2019 무역연구 Vol.15 No.1

This paper investigated the relationship between trade openness and  emissions in Vietnam, using data from 1986 to 2014. We examined the consistency of the environmental Kuznets curve hypothesis and the Pollution Heaven hypothesis as applied to Vietnam. In 1986, the Vietnamese government began to launch free-market economic reforms. Since then, the economy of Vietnam has experienced breakthrough innovation in trade openness. On the other hand, Vietnam has witnessed a growing level of  emissions. Our results showed that the relationship between  emissions and per capita income is an inverted U-shape, consistent with the environmental Kuznets curve hypothesis. We also found that the Pollution Heaven hypothesis is supported in that energy use and international trade contribute to air pollution, but becoming a member of WTO has a positive effect on the Vietnamese environment.

Economic Complexity and Economic Development in ASEAN Countries

Le Thi Thanh Mai,리니엠,김태기 한국국제경제학회 2022 International Economic Journal Vol.36 No.4

This paper investigates the changes in export quality among ASEAN countries over time by using the economic complexity index. Specifically, we used HS 6-digit detailed trade data for 197 countries over the period from 2000-2017. The results show that the economic complexity of most ASEAN countries, except for Cambodia, Laos, and Indonesia, has improved. The export baskets of ASEAN countries are shifting from low complexity products to medium and high complexity products. We also evaluate the export quality of countries using weighted product complexity, which shows that the export quality of ASEAN countries has improved. The regression results show that economic complexity has positive effects on economic growth, and they also show that infrastructure, education level, trade openness, and financial openness contribute to the development of countries. However, the impact extent of economic complexity varies among different ASEAN countries; for example, its impact is weaker in Singapore, Thailand, and Malaysia but stronger in Vietnam, Cambodia, and the Philippines.

TRAN THI THANH MAI,김낭예 한국외국어대학교 동남아연구소 2023 東南亞硏究 Vol.33 No.1

This study aimed to examine the topic selection of the Intermediate 1 Korean textbook for Vietnamese learners. This study compared and analyzed the topics of the Intermediate 1 Korean textbook used in representative Korean (language) departments in the north of Vietnam and the topics level 3 from the ‘Study on the Application of Korean Standard Curriculum for International Communication’. Based on this, the necessary topics used in survey were established. According to the results, a total of 101 sub-topics out of 17 major topics were selected. Using the constructed subject items, the preference survey was conducted targeting Korean (language) students at universities located in the northern region of Vietnam. Based on the preference scores for sub-topics from respondents, this study deduced the average score of major topics and suggested topics for each unit in Intermediate 1 Korean textbook. In addition, based on the reflected results of the preference survey, the educational environment and training time in Vietnam, 14 major topics were selected out of 17 major topics and divided into 14 units (‘Climate’, ‘Food and Drink’, ‘Culture’, ‘Leisure and Recreation’, ‘Work and Occupation’, ‘Travel’, ‘Education’, ‘Shopping’, ‘Personal details’, ‘Emotions’, ‘Daily life’, ‘Interpersonal relationships’, ‘Residence and environment’, and ‘Health’). Hopefully the results of this study will be used as basic data for choosing appropriate topics when developing Korean textbooks for Vietnamese learners in the future. 본 연구는 베트남인 학습자를 위한 중급1 한국어 교재의 주제를 선정하는 것을 목적으로 한다. 이를 위해 베트남 북부 지역의 대표적인 한국(어)학과에서 사용하고 있는 중급1 한국어 교재의 주제와 ‘국제통용 한국어 표준 교육과정 적용 연구’에 제시된 3급 수준의 주제를 비교, 분석하고 이를 바탕으로 선호도 조사에 포함할 주제 항목을 구축하였다. 그 결과 17개의 대주제와 각각의 대주제에 포함되는 101개의 소주제가 선정되었다. 이렇게 구축된 주제 항목을 활용하여 베트남 북부 지역 소재 대학의 한국(어)학과 학생들을 대상으로 선호도 조사를 실시하고, 그 결과를 바탕으로 대주제의 평균점수를 도출하여 중급1 한국어 교재의 단원별 주제를 선정하였다. 또한 선호도 조사 결과와 베트남 현지의 교육 환경 및 교육 시간을 반영하여 14개의 대주제를 선정하고 이를 14개 단원(‘기후’, ‘식음료’, ‘문화’, ‘여가와 오락’, ‘일과 직업’, ‘여행’, ‘교육’, ‘쇼핑’, ‘개인 신상’, ‘감정’, ‘일상생활’, ‘대인관계’, ‘거주와 환경’, ‘건강’)으로 구성할 것을 제안하였다. 본 연구의 결과는 향후 베트남인 학습자를 대상으로 한 한국어 중급1 교재 개발 시 주제 선정을 위한 기초 자료로 활용될 수 있을 것이다.
