本文利用2001—2012年省际面板数据考察了我国产业结构升级是否引致劳动力“极化”现象,以及它们之间的相互作用机理。实证结果表明:我国产业结构升级导致了劳动力“极化”现象的产生,其作用机理体现在产业结构升级所引致的偏向性技术进步会显著增加对高低技能劳动力的需求,使得整个社会劳动力质量向两端偏移。此外,中国劳动力极化还存在区域差异,其中,东部地区呈现高技能偏向型,而西部地区则是非技能型的特点。
In this paper, we use the provincial panel data from 2001 to 2012 to examine whether the phenomenon of “polarization” of labor force and the interaction mechanism between them in China caused by the upgrading of industrial structure. The empirical results show that the upgrading of China’s industrial structure has led to the emergence of the phenomenon of “polarization” of labor force. The mechanism is reflected in the biased technological progress caused by the upgrading of industrial structure, which will significantly increase the demand for highly skilled workers, making the entire social labor force The mass is offset to both ends. In addition, there are also regional differences in the polarization of labor in China. Among them, the eastern region is characterized by high skills and the western regions are unskilled.
