企业城乡劳动力参与“五险一金”差异的实证分析——基于非线性模型的Blinder-Oaxaca分解方法

The Difference and the Cause of Participation in Insurance and Housing Fund between Urban and Rural Labor:A Blinder-Oaxaca Decomposition Method for Nonlinear Regression Models

基于2014年的企业调查数据,利用非线性模型的Blinder-Oaxaca分解方法研究了城镇和农村劳动力参与"五险一金"的差异及原因。研究结果表明,城镇和农村劳动力在参与"五险一金"上存在明显差异,在医疗保险、失业保险、养老保险、工伤保险、生育保险和住房公积金上,均存在对农村劳动力的户籍歧视,户籍歧视分别占城乡总差异的7.99%、13.06%、9.07%、7.62%、26.94%、40.98%,其中生育保险和住房公积金受到的户籍歧视程度最高,表明越基本的社会保险受到户籍歧视的影响越小。

Using the survey data from enterprises in 2014 and the Blinder-Oaxaca decomposition method for nonlinear regression models, the authors studied the difference and the cause of participation in Insurance and Housing Fund between urban and rural labor. The results indicated that there existed obvious differences in Insurance and Housing Fund between the two. Moreover, there was the household register discrimination against rural labor, which in turn accounted for 7.99%, 13.06%, 9.07%, 7.62%, 26. 94% ,40.98% of the total differences in the medical insurance, unemployment insurance, endowment insurance, employment injury insurance, maternity insurance and public housing fund. Among them, maternity insurance andpublic housing fund are the highest level of household register discrimination, which suggests the more basic social insurance, the less affected by household register discrimination.
