A number of studies have indicated that short food supply chains could create economic, social, and environmental benefits, but most of those chains were implemented in developed countries. This research aims to find out the characteristics of short food supply chains and their benefits to small farmers in Vietnam, which is a developing country, based on the survey results from 338 small farmers in the third quarter of 2020, with the support of Stata 14 software. The results showed that the short food supply chains in the survey sample in Vietnam were characterized by two main actors: small farmers and distributors. Farmers could sell products flexibly at the local market. There was some initial evidence to prove that these chains helped to stabilize the input, output price, and revenue; formulated sustainable income; and increased the satisfaction and confidence of farmers. They eliminated gender discrimination in rural areas and improved livelihood for ethnic minorities. These chains also enhanced the mindset on green, organic, and clean production of farmers, which in turn created environmental benefits. COVID-19 has posed a negative impact on the income of farmers and made them change their production and sales method. Therefore, the research could suggest some policies to sustainably develop the short food supply chains in Vietnam in the future.

This study was conducted to examine general information of tax obligations and perceived tax compliance for small and medium enterprises in the district of Gia Lam district. To achieve these objectives, 150 small and medium enterprises were randomly selected and analyzed using descriptive analysis and Principal Component Analysis (PCA). The results show that most of enterprises got difficulties in register, declare and pay taxes, and nearly half of them had submitted taxes lately. Besides, perceived tax compliance of enterprises could be divided into five key factors, including: "Quality of tax services"; "society norms"; "Technology Application"; "Enterprise responsibility "; and "Quality of tax officials". Based on these results, some recommendations could give to the tax authorities in order to improve tax regulations and policies.
