摘　　要：本文基于中国家庭收入调查(CHIP)2013年和2018年数据,利用工具变量法研究了同群效应在农村居民社会养老保险参与行为中的作用。研究发现:(1)同村居民参保率每增加1个百分点,个人参保概率显著增加0.129~0.174个百分点;(2)同村居民缴费水平每提升1个百分点,个人实际缴费额提升的概率增加0.654~0.660个百分点;(3)同村居民平均缴费档次提升1档,个人的实际缴费档次提升的概率增加38.4%~44.4%;(4)在一定条件下,大群组中的同群效应大于小群组;(5)女性群体、高学历者和年轻人群的参保行为具有更大的示范效应。这表明,社会规范和社会学习是同群效应发挥作用的重要机制。Based on the data of CHIP2013and CHIP2018,the paper uses the instrumental variable method to study the role of the peer effect in rural residents'participation in the social insurance of urban and rural residents.It is found that:Firstly,for every 1%increase in the participation rate of peers,the individual participation probability of residents increases by 0.129%~0.174%.Secondly,for every 1%increase in the payment of peers,the individual payment of residents increases by 0.654%~0.660%.Thirdly,the average payment level of peers is increased by 1level,and the probability of the actual payment level of individuals is increased by 38.4%~44.4%.Fourthly,under certain conditions,the peer effects is larger in large clusters than that in small clusters.Finally,the participation behavior of female,highly-educated and young residents has a greater demonstration effect.These results imply social norms and social learning are the main mechanisms of the peer effect.
