购买社会保险能提高农民工主观幸福感吗？——基于上海市2942个农民工生活满意度的实证分析

本研究采用2016~2018年国家统计局上海调查总队农民工市民化进程动态监测调查的2942份农民工样本数据,利用有序Probit模型实证研究了社会保险对农民工主观幸福感的影响。研究表明,购买社会保险可以显著提高农民工的主观幸福感,且购买的社会保险种类越多,其主观幸福感越高。购买社会保险的农民工比未购买社会保险的农民工主观幸福感高21.70%,每多购买一种社会保险,其主观幸福感提高6.10%。五种类型的社会保险均能显著提高参保农民工的主观幸福感,其中购买医疗保险带来的边际效应最高,其次为养老保险,最低的是工伤保险。通过倾向得分匹配法和分样本分析,发现原模型的回归结果具有较好的稳健性。最后,基于研究结论提出了进一步提高农民工群体主观幸福感的政策建议。
