This paper examines the effect of industrial park development on people's livelihoods through different impacting channels; including employment, production means and infrastructure. The result of the research shows that industrial park development had a positive influence on people's livelihoods through additional employment, non-farm investments, access to policies, household labor, etc. However, industrial park development also causes negative impacts on people's livelihoods causing unemployment. Data for research is collected from households including land acquisition and no land acquisition living around industrial parks. Research findings can be considered as a basis to help develop the positive influence and restrict the negative influence of industrial park development on people's livelihoods in Vietnam.

The objective of this study is to analyze the effects of the Covid-19 pandemic on the income of employees who work in the aviation sector in Vietnam. These workers are working in the field that has been most negatively affected by the Covid-19 outbreak. The study uses data collected from 280 Vietnamese employees working in the aviation industry. The pool OLS model is studied and used to analyze the influence of factors on the income of people who work in the aviation sector in Vietnam. The research results show that the Covid-19 pandemic has reduced the earnings of workers in the aviation sector (the effect factor is –5.576921); the income of workers is affected by many factors but in varying degrees such as a work area; gender; educational level; work experience; the number of jobs creating money; personal investments of the part of employees. At the same time, the research findings also show that the difference in the wages of employees in the aviation industry before and after the Covid-19 is vastly different (income difference is about 12.21 million VND/month).

Evaluating the socioeconomic efficiency of scientific and technological topics/projects after acceptance is very difficult because it is not easy to find common ground on the criteria for evaluating the socioeconomic efficiency of topics/ projects of different research fields. Hence, depending on researchers' views, the evaluation criteria or the weight of evaluating the socioeconomic efficiency of each topic/project should be different. This study uses the expert method and the Analytic Hierarchy Process (AHP) method to determine the criteria and to calculate weights for criteria on five scientific fields according to scientific sub-disciplines in Binh Dinh province, including agricultural science, natural science, social sciences and humanities, medical science, engineering and technological sciences. Our research shows that the evaluation of the socioeconomic efficiency of the provincial topics/projects should be based on eight aspects, including science, technology, economics, environment, culturesociety, information-management, and education. At the same time, the results also identified a set of common criteria for evaluating the socioeconomic efficiency of topics/projects and suggested how to calculate points and to rank the effectiveness of topics/projects. However, the weight of the criteria and the composition of each criterion is different.
