我国工资差距的影响因素分析——基于制造业面板数据的研究

本文借鉴成本函数的研究方法,采用我国1993～2010年19个工业细分行业的相关数据考察了影响熟练劳动与非熟练劳动相对工资变化的因素。通过计算行业的VSS和回归估计发现,国际贸易和技术进步才是拉动我国相对工资差距的主要原因,外包对相对工资差距起到微弱的缩小作用。根据行业的要素密集度,本文继续将工业行业划分为3个子样本,进一步考察了这些因素对不同要素密集型部门的相对工资的影响,结论与总体回归基本一致。本文的结论与理论预期的不一致,可能是由中国劳动力市场的特殊性和中国加工贸易的特点决定的。

The Influencing Factors of China's Wage Gap:An Analysis based on Panel Data of Manufacture Industries

Based on cost-function research method and China′s 19 industrial sub-sectors′ data from 1993 to 2010,this paper studies the factors which affect relative wage between skilled labor and unskilled labor.By calculating VSS and regression estimation,it finds that international trade and technological change are main reasons for driving China′s relative wage gap while outsourcing is playing a weak role to narrow the gap.It also classifies industrial sectors into three sub-samples according to input intensity,and separately estimats the effects of these factors in different input-intensive sectors.Conclusions are consistent with the overall estimation.Those conclusions are inconsistent with the theoretical expectations,which may be explained by the specificity of China′s labor market and the characteristics of China′s processing trade.
