Abstract: The implementation of the rural revitalization strategy, the belt and road initiative, and the policies to revitalize border areas and enrich the people have made the southwest border area at the forefront of China’s opening-up. The hollowing out of China’s southwest border is related to a series of issues such as territorial security, economic construction and development, population migration and flow in China’s border areas. This article analyzed the causes and influences of border area hollowing from the perspective of micro and macro, proposed that the governance of hollowing in border areas should take security as the premise, stability as the guarantee and development as the key, and put forward relevant suggestions from multi-subject and multi-perspectives at the micro level, which had important theoretical and practical significance for the hollowing out of China’s border areas.

Key words: rural revitalization strategy, the southwest border, hollowing out, the floating population
