劳动力市场城乡分割与劳动收入比重*--基于中国省级面板数据的分析

摘要

In this paper,we study on the variations in labor income share from the angle of labor market urban-rural segmentation.We find that the relationship between the labor market urban-rural segmentation and the labor share in china is bilateral Granger causality.The labor market urban-rural segmentation decrease agricultural marginal output.The decline of agricultural marginal output results in the low rural labors reservation wages and city workers wages;and this will decrease labor share. On the other hand,the decline of labor share results in the insufficient of the human capital investment and the increasing of unskilled workers proportion;and this further raises the level of the labor market urban-rural segmentation.So taking the efficient steps to reduce the labor market urban-rural segmentation is the key element to stabilize the labor share.%基于劳动力市场城乡分割的视角对中国劳动收入比重的变动原因进行研究，发现劳动力市场城乡分割与劳动收入比重之间互为因果：中国劳动力市场城乡分割会使农业边际产出下降，降低农村劳动者的保留工资，制约城市劳动者的工资水平，导致劳动收入比重下降。而劳动收入比重下降会使劳动者减少人力资本投资，增加低技能劳动者比例，加剧劳动力市场城乡分割程度。因此，减弱劳动力市场城乡分割是稳定劳动收入比重的关键。
