Abstract: The substantially unified calculation and payment method is the proper meaning of national overall planning of the basic endowment insurance in China. However, the current calculation and payment method is compatible with the provincial overall planning, which cannot meet the requirements of further improvement of the overall planning level. Based on the constraints of improving the level of overall planning, this paper designs three plans for calculation and distribution that are compatible with the national overall planning on the basis of the current calculation and distribution method; and these three plans are tested from the perspective that the treatment level of the insured individuals does not decrease and the local financial burden is affordable. The results show that if the national social average wage is used to replace the regional social average wage in the current calculation and payment method, it can not only produce a stronger regional income redistribution effect, but also minimize the total amount of financial subsidies for each local government. Therefore, it is suggested to adopt this scheme topromote the realization of the national overall planning.

Key words: national overall planning, basic pension calculation and payment method, individual target constraint of participating in insurance, local financial target constraint
