The policy of social insurance premium reduction and mitigation has been implemented in strict accordance with the overall national deployment in Sichuan. The burden of enterprises has been effectively reduced with work and production resumed. Especially for small and medium-sized enterprises，it plays an important role in tiding over difficulties in the epidemic and reducing the burdens of enterprises and low-income participants. However，these policies have also triggered greater pressure on the provincial social insurance fund. Several policies need to be improved in that problems emerge in the implementation. This paper puts forward relevant suggestions to further implement the policy of social insurance reduction and mitigation，strengthen the fund collection management and ensure the long-term stable operation of social insurance fund.
