In the new development pattern, under the background of the mutual promotion of domestic and international double cycles, the future development trend will attach great importance to demandside management. Nowadays, the focus of absolute poverty governance has shifted to the field of relative poverty governance. The development of the social assistance system is in a transitional period of assistance demand acceptance, resource optimization and integration, and capacity expansion. There are both supply and demand misplacement problems such as “inaccurate aiming”, “being inaccessible”, and “being inactive”. This paper suggests carrying out the vertical stratification and horizontal classification design of the social assistance system according to the group characteristics and differences in needs, and classifying the subsistence allowance group, the extremely poor, the lowincome group, the expendituretype poor group and the groups in need into “three circles”. And this paper proposes the implementation of precise classification management in the assistance system, and attempts to design a system linkage mechanism that links social assistance reforms and rural revitalization strategies with a view to boosting the highquality development of social assistance.
