【Abstract】Intergenerational equity is the intrinsic value basis of the pay-as-you-go pension insurance system. This paper uses the intergenerational accounting method to analyze the impact of fee reduction on the intergenerational fairness of the basic old-age insurance system for urban workers in China, and finds that the intergenerational unfairness of the system before the fee reduction is prominent, and the payment burden of male employees of the same generation is significantly higher than that of women. Based on this, this paper designs six different fee reduction schemes for pooled accounts to investigate the impact of continuing to reduce the contribution rate on intergenerational equity, and the results show that with the continuous reduction of the contribution rate, the contribution of each generation to the system is "ironed out" to a certain extent, and the difference between generations within different genders is getting smaller and smaller. Based on the combined results of the percentage imbalance and the lifetime net tax rate determination, the 13% contribution rate is the optimal contribution rate that can achieve relative intergenerational equity. With the adjustment of the social insurance premium collection agency and the promotion of a new round of fee reduction, the contribution rate should be further reduced to 13% at an appropriate time.
