外来人口自雇创业的城镇医疗保障效应——以基于广州外来人口的实证分析

The Urban Medical Security Effects of the Self-employed Migrants——An Empirical Study of the Field Survey of the Migrants in Guangzhou

随着城市外来人口的不断增加,自雇创业成为外来人口重要的就业形式,而关于自雇与受雇两种就业形式的比较研究也越来越为重要。基于2015年全国流动人口动态监测调查广州数据,本文采用倾向得分匹配中的卡尺匹配,在消除自雇者样本选择性偏差问题的基础上,比较研究了外来人口受雇就业与自雇创业者间的城镇医疗保障差异。结果表明,在其他条件相同的情况下,外来人口自雇创业者在城镇医疗保障参与度方面明显低于受雇者,自雇就业形式对于外来人口的城镇医疗保障具有负向效应。

With the increase of urban migrants,self-employment has become the main form of employment.Thus,the comparative employment study of the self-employed and the employed workers draws an increasing attention from researchers.Based on the data of Guangzhou from the national migrants dynamic monitoring surveys in 2015,this paper has made a comparison of the urban medical security effects between the selfemployed and employed migrants by using the caliper matching of the propensity score matching and eliminating the sample selection bias of the self-employed workers.The result of the study shows that,under similar conditions,the urban medical security participation of the self-employed migrants is significantly lower than that of the employed workers and the self-employment has a negative effect on the urban medical security.
