Environmental pollution is becoming an urgent global issue. Countries are implementing various solutions and establishing legal frameworks and institutional policies to promote the use of green energy sources and thereby minimize the adverse environmental impact of economic growth, investment, and consumption. The goal of economies worldwide, including in Asia, is to implement policies that promote sustainable development while optimizing economic performance. The purpose of this study is to evaluate the impact of green energy consumption and institutional quality on environmental quality. Using data from 29 selected Asian countries over the period 1970–2021, the empirical results indicate that green energy consumption does not have a statistically significant impact on environmental quality across the full sample. Improvements in institutional quality can enhance environmental quality and accelerate progress toward carbon neutrality and net-zero emissions targets. The Climate Change Conferences (COPs) have helped raise global awareness of the dangers of climate change, fostering greater international cooperation to protect the planet and promote sustainable development. To capture the influence of international climate commitments, this study employs a dummy variable for the COP period (coded 0 before COP2 in 1996 and 1 thereafter). This variable is interacted with green energy consumption and institutional quality to examine whether the implementation of COP commitments moderates their effects on CO₂ emissions. The empirical results show that greater political stability, particularly during the implementation of carbon emission reduction commitments, contributes to reducing greenhouse gas emissions and promoting sustainable development. The study also confirms that institutional quality plays a significant role in improving environmental quality and accelerating countries’ progress toward carbon neutrality and net-zero emission goals.

This study aims to investigate the impact of corporate social responsibility (CSR) on competitive advantage in Vietnamese small and medium-sized enterprises (SMEs), with a particular focus on the mediating roles of corporate reputation, corporate brand, and customer loyalty. This study employs a quantitative research design using survey data collected from 137 managers and staff across Vietnamese SMEs. The partial least squares path modeling (PLSPM) method is applied to test the proposed structural model and hypotheses. The findings reveal that CSR does not have a direct significant effect on competitive advantage. Instead, CSR exerts a strong positive indirect effect through corporate reputation. Specifically, CSR significantly enhances corporate reputation, which in turn improves both customer loyalty and competitive advantage. However, the direct effects of CSR on customer loyalty and of corporate brand on customer loyalty are found to be insignificant. These results indicate that reputation serves as the primary strategic mechanism through which CSR creates value for firms. For practical implications, SME managers in emerging markets should prioritize CSR initiatives that are visible, credible, and stakeholder‑oriented to build reputation, rather than relying on CSR or branding alone to drive customer loyalty or competitive advantage. Managers should treat reputation as a strategic asset, communicate CSR transparently, and integrate CSR into broader trust‑building strategies. Given limited resources, SMEs should focus on high‑impact CSR activities that resonate with stakeholders. This study contributes to the literature by demonstrating that CSR enhances competitive advantage indirectly through corporate reputation rather than directly, and it provides actionable insights for leveraging intangible assets to achieve long‑term sustainability.

Vấn đề biến đổi khí hậu và môi trường hiện nay đang đặt ra yêu cầu bức thiết với thế giới phải chuyển đổi từ nền kinh tế truyền thống (kinh tế tuyến tính) sang nền kinh tế tuần hoàn nhằm đạt được các mục tiêu phát triển nhưng vẫn bảo vệ và giảm thiểu tác động đến môi trường sống của chúng ta. Việt Nam cũng không nằm ngoài yêu cầu đó vì chúng ta luôn là một trong số các nước bị ảnh hưởng nhiều nhất bởi biến đổi khí hậu toàn cầu. Hà Nội, trung tâm kinh tế, văn hoá của Việt Nam, nơi có hơn một nửa diện tích đất đai là đất nông nghiệp (58,91%) nên vấn đề áp dụng kinh tế tuần hoàn tại Hà Nội lại càng cần ưu tiên áp dụng và nêu gương để có thể trở thành đầu tàu cho các địa phương khác trên cả nước. Tuy nhiên, vấn đề áp dụng kinh tế tuần hoàn vào nông nghiệp tại Hà Nội mặc dù không mới nhưng việc triển khai và nhân rộng vẫn còn gặp rất nhiều khó khăn. Bài nghiên cứu này được tác giả thực hiện nhằm nghiên cứu các yếu tố ảnh hưởng tới ý định áp dụng kinh tế tuần hoàn vào nông nghiệp của nông dân khu vực Hà Nội, để từ đó có thể đề xuất một số biện pháp thúc đẩy việc áp dụng kinh tế tuần hoàn vào nông nghiệp của người nông dân tại đây. Nghiên cứu đề xuất mô hình lý thuyết kết hợp sử dụng lý thuyết hành động hợp lý (TRA) và lý thuyết hành vi dự định (TPB). Qua phân tích 154 mẫu khảo sát, phần mềm STATA được sử dụng để phân tích dữ liệu phản hồi hợp lệ. Nghiên cứu đã chỉ ra rằng ý định áp dụng nông nghiệp tuần hoàn của nông dân Hà Nội bị ảnh hưởng trực tiếp từ nhận thức kinh tế tuần hoàn và thái độ đối với nông nghiệp tuần hoàn của họ. Ngoài ra, các yếu tố sự quan tâm phúc lợi xã hội và nhận thức lợi ích kinh tế có tác động gián tiếp lên ý định áp dụng nông nghiệp tuần hoàn qua biến trung gian là thái độ đối với kinh tế tuần hoàn trong nông nghiệp.

The study aimed to assess factors influencing the intention to participate in voluntary social insurance among informal sector workers in Vietnam, an emerging economy in Southeast Asia. Primary data collected from 460 respondents was used for SEM analysis. The study showed that two parts of the Theory of Planned Behavior (TPB) model—attitude and perceived behavioral control—make people more likely to sign up for voluntary social insurance. Government incentive policies, appropriateness, affordability, and perceived difficulties during the COVID-19 pandemic also predict the intention to participate. The research findings rejected the role of subjective norms in influencing the intention to participate. This research has identified factors affecting intention to subscribe to voluntary insurance among independent laborers in an emerging market like Vietnam, where there used to be larger proportion of formal workers who had to follow mandatory social insurance. Based on the revealed impact factors, policymakers and labor-related authority officials may have insights into how to encourage more informal workers to purchase voluntary insurance. This is particularly critical in a context where the majority of the population, especially independent laborers, are not used to subscribing to insurance in general if not required.

The social welfare system is an important way to provide employment and income for informal labor in the context of shock economies in rural areas. This study evaluates factors impacting the employment status of rural informal labor during the time of the COVID-19 pandemic in rural Vietnam. This paper uses two models, including a binary logistic regression model and a quantile regression model, with survey data collected from 215 rural informal laborers. The results show that marital status, education, and health positively affect employment status. However, age, gender, and head of household are not identified as significant factors. The results also show that single laborers have lower chances of employment because they do not have to take care of raising their children and other members of their families. Furthermore, our models also confirm that rural informal laborers entitled to basic living allowances are less likely to be employed, but the finding is that employment and entrepreneurship services lead to a higher likelihood of being used among these laborers during COVID-19. Besides, this paper gives some policies to help informal laborers find jobs during the COVID-19 pandemic. Primarily, the research focused on the influence of social security programmes on the employment situation of rural informal labor in emerging nations such as Vietnam, particularly amid economic upheavals like the COVID-19 pandemic.

New business models integrated with technological advances like online food ordering platforms have been increasingly prevalent and are believed to bring significant value to customers. This study applied the theory of planned behaviour (TPB) to examine how several factors influence the continuance usage intention of Gen Z customers when using food delivery applications (FDAs). Results from the CB-SEM analysis reveal that personal innovativeness positively influences the attitude of Gen Z customers. Continuance usage intention is positively influenced by attitude, perceived usefulness of promotion, and subjective norm. On the contrary, perceived health risk is indicated as a significant barrier to the perceived usefulness of promotion and continuance usage intention of Gen Z customers. These findings suggested discussions and have implications for stakeholders such as researchers, technology providers, enterprises, and policymakers.

Chính sách giáo dục đóng vai trò quan trọng trong phát triển kinh tế - xã hội, góp phần nâng cao nguồn nhân lực của khu vực nông thôn cũng như góp phần giúp các lao động nông thôn có khả năng tìm kiếm các cơ hội việc làm và từ đó cải thiện thu nhập của các hộ gia đình. Thông qua việc khảo sát điều tra 270 hộ gia đình khu vực nông thôn tại 3 tỉnh Hà Giang, Hà Tĩnh và Trà Vinh, bài viết sử dụng phương pháp phân tích đa tiêu chuẩn (MCA) với quy trình phân tích thứ bậc (AHP) để đánh giá các yếu tố tác động đến hiệu quả thực hiện chính sách giáo dục đối với thu nhập của hộ gia đình ở khu vực nông thôn Việt Nam. Kết quả cho thấy các yếu tố kinh tế (0,39) có ý nghĩa quyết định đến hiệu quả thực hiện chính sách giáo dục, tiếp theo là chính trị (0,21), khoa học công nghệ (0,21) và cuối cùng là yếu tố xã hội.

Credit is considered as an essential tool to make informal labor’s income better. In order to improve quality of their life, the state should have some supports them in credit access. This study analyzes factors causing credit access of informal labors to be changed in the time of COVID-19 pandemic. Using survey data collected from 2020 VHSSL (2019–2020), this approach has two models including a binary logit model and a multinomial logit model (MLM). The results revealed that the positive factors including education, material, collateral, credit size, credit source, credit debt which are likely to affect to credit access, however age, family size, ethnicity, interest, paid money are negative. Besides, it also concludes that quality of life of informal labor is considerably influenced by credit access, collateral, credit source, credit debt from the observed samples. Additionally, this paper recommends some policies to enhance informal labor’s access to credit and their quality of life.
