To realize common prosperity，we must correctly understand and manage the relative poverty formed in the process of development. Relative poverty governance is not only the objective requirement to improve the efficiency of poverty governance，but also the only way to achieve the goal of common prosperity. Sichuan Province is one of the provinces with the heaviest task of poverty alleviation in China and the main battlefield of poverty alleviation in China. Poverty is large，wide and deep. It faces both national common problems and local individual problems. Relative poverty，especially in rural areas，has become the difficulty and focus of realizing common prosperity in Sichuan to a certain extent. This paper mainly puts forward relevant countermeasures and suggestions from the construction of a diversified and dynamic relative poverty governance mechanism and their coordination，so as to realize the balanced integration of academic logic，social logic and policy logic.
