摘　　要：本文利用中国家庭追踪调查数据(CFPS),基于微观收入数据通过收入转移矩阵建立收入流动性指标,运用有序Probit模型与倾向匹配得分模型(PSM),实证检验了社会保险对收入流动性的影响及作用机制。研究结果表明:第一,社会保险的覆盖面与全面性在收入流动性中发挥着正向激励收入阶层"向上流动"的作用;第二,社会保险的五大分类保险在收入流动性上均呈现显著的正向影响;第三,无论是城市居民还是农村居民,社会保险对收入流动性的提升均具有显著的积极作用,而社会保险的全面性对农村居民收入流动性的提升效果更佳。By constructing the indicator of income mobility through the income transition matrix based on the micro income data of China Family Panel Studies(CFPS),this paper uses the ordered probit model and the propensity score model(PSM)to examine the impact and mechanism of social insurance and income mobility.The results are shown as follows.First,both the coverage and comprehensiveness of social insurance play a positive role in promoting the upward mobility of the income classes in the income mobility.Second,the five categories of social insurance have a significant positive impact on the income mobility.Third,the social insurance has a significant positive effect on promoting the income mobility of both urban and rural residents,but the comprehensiveness of social insurance has a better effect on promoting the income mobility of rural residents.
