基于大规模的流动人口调查数据,本文研究了城乡分割和区域分割对城市外来流动人口社会保障的影响。利用变量法的IVProbit模型进行回归估计,尝试解决劳动者的工资与参加社会保险之间的内生性问题。研究结果发现：第一,外来流动人口参加社会保险存在严重的城乡分割和区域分割效应;第二,区域分割效应大于城乡分割效应;第三,若不解决工资与社会保险参保之间的内生性问题,则将低估外来流动人口参加社会保险的城乡分割效应和区域分割效应。
基于大規模的流動人口調查數據,本文研究瞭城鄉分割和區域分割對城市外來流動人口社會保障的影響。利用變量法的IVProbit模型進行迴歸估計,嘗試解決勞動者的工資與參加社會保險之間的內生性問題。研究結果髮現：第一,外來流動人口參加社會保險存在嚴重的城鄉分割和區域分割效應;第二,區域分割效應大于城鄉分割效應;第三,若不解決工資與社會保險參保之間的內生性問題,則將低估外來流動人口參加社會保險的城鄉分割效應和區域分割效應。

The purpose of this paper was to examine the effect of urban-rural division and regional segmentation on the social security access of China＇s migrant workers.The data collected by the China＇s National Health and Family Planning Commission in December 2010.The instrumented IVProbit model was adopted to solve the endogeneity problem between wage and participation in social insurance of the workers.We found that there existed serious effects of urban-rural division and regional segmentation on the access to social insurance for the migrant workers.The level of effect of the regional segmentation was higher than that of the urban-rural division.Furthermore,both the effects of urban-rural division and regional segmentation would be lower estimated if the endogeneity problem was not solved.
