摘要: 作为国际经济学研究的重要命题之一,外商直接投资对劳动力市场的收入分配效应历来备受关注且尚无定论。本文利用2002年和2007年中国城镇住户调查数据(CHIP),将劳动力个体特征变量与城市宏观变量相结合,通过两阶段最小二乘和工具变量分位数回归方法(IVQR),实证考察了外资进入对城镇居民性别工资差距的影响。研究发现:(1)总体来看,外资进入对男性和女性工资都有显著的正向影响,且对男性的工资提升作用明显强于女性,性别工资差距被拉大;(2)从技能水平看,尽管外资进入对不同技能水平的男性和女性工资均有正向影响,但二者差距仍被进一步拉大,且不同年份不同技能水平表现各异;(3)从收入分布看,外资进入总体上对中低收入群体性别工资差距的拉大作用强于高收入群体,且在不同年份均有一致表现。

Abstract: As an important research field of international economics, the income distribution effect of foreign direct investment to the labor market has always been attracting much attention, but hasn’t come any consistent conclusion. Based on Chinese Household Income Project (CHIP) in 2002 and 2007, this paper empirically examines the impact on urban residents’ gender wage gap of foreign investment. Especially, the individual characteristics and urban macroscopic variables are combined in this paper, In order to reduce the endogeneity, the author uses 2SLS and IVQR. The study found that: (1) foreign investment have significant positive influence on wages for both male and female, but the male’s wage increase obviously faster than female, and the gender wage gap is widening; (2) although foreign investment has positive influence on wages of male and female with different skill, but the gender wage gap is still widening; (3) foreign investment has a larger impact on the gender wage gap of medium and low-income groups than high-income groups, which is consistent in 2002 and 2007.
