外包与工资差距:基于工业行业数据的实证研究

笔者以Feenstra等人的三要素模型为基础,分析了国际外包影响发达国家及发展中国家熟练劳动力与非熟练劳动力之间工资差距的理论机制,运用我国工业行业面板数据,实证检验了外包对我国工业行业总体及分部门工资差距的影响。结果表明:外包和技术进步对我国工业行业熟练劳动力与非熟练劳动力之间工资差距的扩大均存在明显的正效应,但外包对劳动力资源密集型部门和中等技术部门的影响效应相对更强。

Outsourcing and Wage Gap : Empirical Study Based on China's Industrial Data

Based on the three-factor model of Feenstra R C et al(1997),this paper analyzes the theoretical mechanism of the impact of international outsourcing on wage gap between skilled labor and unskilled labor in developed and developing countries with an empirical study on how outsourcing activities affects the wage gap in overall and sub-sectors of China’s industry by using industrial panel data.It is found that international outsourcing and technological progress both have significant positive effect on the expansion of wage gap in China’s industrial sectors,but outsourcing activities has relatively stronger effect on the labor resources-intensive sector and the medium-technology sector.Thus,China should develop effective income distribution policy to better deal with the relationship between efficiency and equity.
