Abstract: Lowering the rate of pension insurance is an important part of the reform of the supply side—“three down and one fill”, and the upgrading of industrial structure is a macro factor affecting pension contribution’s deviation. The paper analyzes the effects of different industrial structure upgrading on pension contribution’s deviation.The paper found that: extensive upgrading of industrial structure leads to lower employment and income stability, the actual contribution rate of endowment insurance is lower than the theoretical rate of payment, and pension insurance dropping in space; negative influence of industrial structure upgrading to pension contribution is realized by mediating effect, including pension contribution extrusion effect and pension contribution reduction effect; in the realization of the internal structure of technology to optimize the industrial level in the process of upgrading the industrial structure, the negative impacts of the extensive upgrading of the industrial structure on the old-age insurance payment are reduced; with the upgrading of the industrial structure rationalization, the level of old-age insurance fee reduction space also increases. At the same time, the deviation effect of extensive industrial structure upgrading and the incentive contribution effect of the optimization of internal industrial technology structure vary in different regions, and the eastern region is more significant than the central and western regions.

Key words: industrial structure upgrading, the internal optimization of industry, reduced rate of pension insurance, the deviation index of pension contribution
