中文摘要：

基于HO定理的SS定理适合解释一般贸易背景下的工薪差距问题,基于中间产品贸易的SS定理适合解释中间产品贸易背景下的工薪差距问题,因此实证研究我国的对外贸易与工薪差距问题应该区分一般贸易和加工贸易分别进行.以2005年至2009年我国29个行业面板数据为样本,在划分技术密集行业和非技术密集行业的基础上,实证检验了加工贸易对工薪差距的影响.结果发现：我国非技术密集行业加工贸易的发展拉大了工薪差距,技术密集行业开展的加工贸易活动对工薪差距无显著影响.无论是非技术密集行业还是技术密集行业,资本密集度、技术进步、行业规模对工薪差距都没有显著影响.

英文摘要：

The SS theorem based on HO model is suitable for explaining the wage inequality in the context of general trade, and the SS theorem based on intermediate goods trade can be used for the interpretation of wage gap caused by the intermediate goods trade. Thus we need to distinguish general trade and processing trade when we analyze the relationship between foreign trade and wage inequality. We use China＇ s 29 industries from 2005 to 2009 as samples, and divide them into technology-intensive and non-technology-intensive industries, estimating the effect of the processing trade on wage gap. The resuh shows that the processing trade of non-technology-inten- sive industries increases the wage inequality, but the processing trade of technology-intensive industries has no significant effect on wage gap. Moreover, capital intensity, technological change and scale have no influence on wage inequality both for technology-inten- sive industries and non-technology-intensive industries.
