本文采用基于倾向得分匹配的双重差分模型（PSM-DID）系统地评估了外向型FDI对企业职工收入的微观影响。首先通过典型化事实分析发现,自2004年以来中国企业职工工资水平持续上升,但与此同时,企业内工资差距也在逐步扩大;在此基础上利用中国2004-2008年的微观企业数据进行实证检验,结果表明,企业外向型FDI显著地提高了职工的平均工资水平,并且外向型FDI也显著地拉大了企业内工资差距,这意味着与非技能工人相比,技能工人的工资水平在企业对外直接投资之后实现了更大幅度的增长。本文的结论表明,企业在实施＂走出去＂战略的同时,需要进一步完善职工培训体系以防止企业内部工资差距的持续过度拉大。

In the context of implementation of the going-out strategy, this paper adopts the method of Difference-in-Difference combined with propensity matching score（PSM-DID） to comprehensively estimate the micro effects of firms＇ outward foreign direct investment on their employees＇ income. Firstly, the analysis on stylized facts shows that, employees＇ income has been rising since 2004 but so has been the wage inequality within firms. On this basis, the paper conducts an empirical study by using Chinese micro firm-level data from 2004 to2008. The results show that, firms＇ outward foreign direct investment significantly raises employees＇ average income, and it also significantly widens wage inequality, which implies that compared with the wage of non-skilled labor, that of skilled labor has risen more substantially after the firms starts to invest outward.The above results indicate that while implementing the going-out strategy, it is needed to further improve the staff training system to avoid widening wage inequality within firms.
