中文摘要:
      研究目标：研究了养老保险缴费的收入分配效应，并针对2005年养老保险改革研究其政策效应。研究方法：采用微观调查数据构造城市层面的面板数据，构建面板固定效应模型进行估计。研究发现：养老保险覆盖率和替代率有助于缩小收入差距，在收入再分配中发挥着积极的作用，而养老保险缴费对收入差距存在逆向调节作用。在2005年养老保险改革之后，养老保险缴费的逆向分配效果得到一些改善。机制分析表明，养老保险缴费存在累退的性质，相比低收入群体，高收入群体的边际缴费率更低，这直接导致了缴费率对个体劳动收入的“逆向分配”效应，从而降低了养老保险整体对收入再分配的调节作用。研究创新：探索了养老保险与收入差距之间的关系，并深入研究了养老保险缴费影响收入差距的传导机制。研究价值：为我国推进养老保险体系改革提供新的研究视角，为政府缩小收入差距、实现共同富裕提供经验证据。
英文摘要:
      Research Objects: This paper studies the income distribution effect of pension contribution, and then explores the impact of pension reformed in 2005 Research Methods: This paper uses micro-data to construct city-level data, then constructs panel fixed effects model to do the estimation Research Findings: Pension coverage and replacement have positive adjustment effects on income inequality, and pension contribution has a negative adjustment effect on income inequality While after pension reformed in 2005, the reverse distribution effect of pension contribution has been improved The further analysis of mechanism shows that the pension contribution is regressive Compared to low-income groups, high-income groups have lower marginal contribution rate, which directly leads to the “reverse distribution” effect of pension contribution on individual labor income, thus reduce the overall adjustment effect of pension security on income redistribution Research Innovations: This paper explores the relationship between pension security and income inequality, and further explore its impact mechanisms of pension contribution on income inequality Research Value: This paper provides new research perspectives for promoting the reform of pension security system, and provides empirical evidence for government to reduce income inequality and achieve common prosperity
