文章构建开放条件下三部门内生技术进步的理论模型,发现伴随产业集聚度增加,FDI技术溢出效应呈现倒U型变化特征。利用2003-2011年中国制造业20个产业数据和系统GMM回归方法实证验证了该理论结论,结果表明：产业集聚通过规模经济效应和市场竞争效应促进了FDI技术溢出,而通过劳动力禀赋和研发投入水平增长对技术溢出促进作用相对较小。在此基础上提出促进不同集聚度产业FDI技术溢出的不同途径。

The paper constructs the endogenous technological progress model of three departments in opening conditions. It concludes that agglomeration’s FDI technology spillover effects presents the characteristics of invert-U shape with increasing agglomeration degrees. The empirical test using the data of China’s 20 manufacture industries during 2003 to 2011 supports the conclusion. The results are: industrial agglomeration promotes FDI Technology Spillover through effects of scales economy and market competition, while having little effects by labor endowment and R D increasing. Based on it, different paths to increase FDI Technology Spillover for different agglomeration industries are proposed.
