自雇何以影响农民工健康权益可及性--基于CMDS数据的实证分析

How Self-employment Affects Migrant Workers’Access to Health Rights:Empirical Analysis Based on CMDS Data

自雇已成为农民工城市就业中日益普遍的方式。本文利用中国流动人口动态监测调查数据(CMDS),分析了自雇对农民工健康权益可及性的影响。研究发现,自雇对农民工健康权益可及性具有显著的正向作用,而且这一现象存在性别、代际和区域的异质效应,对于男性、老一代农民工和东部地区更显著。分位数回归结果显示,在低分位点上,自雇的影响不明显,但随着分位点的上升,自雇的影响程度显著提高,与农民工健康权益可及性呈现高阶相关性。进一步分析表明,自雇既通过影响健康档案、健康教育与医疗服务可及性对健康权益可及性产生正向作用,又因社会保障的相对缺失对健康权益可及性产生削弱作用。在采用内生性处理与稳健性检验后,结论依然成立。

Self-employment has become increasingly common in urban employment of migrant workers.Using the data from China Migrant Population Dynamic Monitoring Survey(CMDS),this paper analyzes the impact of self-employment on the accessibility of migrant workers'health rights.The study finds that Self-employment has a significant positive effect on the accessibility of migrant workers'health rights,and there are gender,generational and regional heterogeneous effects of this phenomenon,more significant for men,older generation migrant workers and eastern regions.Quantile regression shows that the effect of self-employment is insignificant at the low quantile,but increases significantly as the quantile rises,showing a higher order correlation with the accessibility of migrant workers'health rights.Further analysis shows that self-employment not only has a positive effect on the accessibility of health rights and interests by affecting the accessibility of health records,health education and medical services,but also has a weakening effect on the access to health rights and interests due to the relative lack of social security.After using endogeneity treatment and robustness test,the conclusion still holds.
