Abstract:

The existing research has not yet answered the question how the labor market segmentation will influence the wage distortion. In this paper, we toke the method of stochastic frontier analysis (SFA) based on translog production function and estimated the wage distortion index of industrial sector in Chinese provinces, and then using the method system GMM which can effectively control the endogeneity problem of estimation, investigated the effects of labor market segmentation and other factors on the wage distortion. We found that: the wage distortion of industrial sector in Chinese provinces is much more serious than the existing researches’ conclusions, which showed an increasing trend, and the wage distortion of the eastern regions was significantly higher than that of the central and western regions; The degree of labor market segmentation in western remote areas is much heavier, but the eastern coastal of which is to a lesser extent; The labor market segmentation and the rising proportion of foreign investment will worsen wage distortion, but the increasing innovation investment, and the implementation of “labor contract law” will ease the wage distortion. Therefore, the government should first gradually eliminate labor market segmentation among the provinces and cities, which helps to ease the degree of wage distortion.

摘要：

劳动力市场分割会对工资扭曲产生何种影响，现有研究尚未做出解答。本文基于超越对数生产函数的随机前沿分析（SFA）方法测算了中国省际工业部门的工资扭曲指数，之后通过可以有效控制内生性问题的系统广义矩估计方法考察了劳动力市场分割等因素对工资扭曲程度的影响，我们发现：中国省际工业部门的工资扭曲程度要比现有研究结论严重的多，工资扭曲程度呈现加重态势，且东部地区的工资扭曲明显高于中西部地区；西北偏远地区的劳动力市场分割程度较重，东部沿海省份劳动力市场分割程度较轻；劳动力市场分割、外资比重上升将会加剧工资扭曲程度，而创新投入比重上升、《劳动合同法》的实施将会缓解工资扭曲现象。因此，逐步消除各省市之间的劳动力市场分割现象，可以有效缓解中国工业部门的工资扭曲现象。
