基于1988-2007年CHIP城镇入户调查数据，本文采用Oaxaca—Blindex分解、分位数回归考察了贸易自由化对我国收入差距的影响。结果表明：第一，贸易自由化提高了贸易部门非技能劳动者的收入水平，并在1995年后超过非贸易部门非技能工人的回报且呈逐年拉大趋势；第二，贸易部门与非贸易部门大专及以上教育回报率均呈上升趋势，2002年及以前非贸易部门大专及以上教育程度的回报率明显高于贸易部门，但2007年低于贸易部门。因此，贸易自由化引起的技能偏向而导致教育收益的改变是造成中国收入差距扩大的重要因素。

Based on the Ofinese Household Income Project Survey, this paper explores the impact of trade lib- eralization on the wage gap in China at different quantiles using the methods of Oaxaca- Blinder decomposition, quantile regression and quantile decomposition. The results show the early trade liberalization narrows the un- skilled worker＇s wage gap between trade sector and non- trade sector, but because of the level of human capi- tal, trade sector wage level is still lower than the non - tradable sector. With the development of trade liberal- ization, the trade sector demands more skilled workers and increases the skilled workers＇ wage level of trade sector, but due to the level of human capital weaknesses as well as a large number of middle - income wages lower than the non- tradable sector, the total wage level of trade sector is still lower than the non - tradable sector.
