本文采用2000-2011年我国14个工业行业面板数据,首次构造相对应的解释变量区分示范效应、竞争效应和人员流动效应,并在不同技术层面上,实证检验出外商投资对我国内资企业技术溢出效果的差异,通过分析发现:一,示范效应下的模仿学习渠道获取的技术外溢,仅在企业劳动生产率产生促进作用,在新产品市场转化和专利研发层面产生显著的抑制作用；二,竞争效应下的技术解译渠道获取的技术外溢,尚未帮助内资企业突破技术进步的路径依赖关系；三,外企技术人员流入内企的规模和技术层次都不高,仅仅在新产品市场转化层面产生显著的技术外溢效果.%Using Panel Data of our 14 industries' from 2000-2010, this paper constructs independent variables corresponding to demonstration effects, competitive effects and worker mobility effects for the first time, and positively inspects the different effects of FDI spillovers at various levels. We found that the technology spillover effects of imitation from foreign enterprises could promote our progress in productivity, but hinder our progress in innovation. Moreover, spillover effects of technology interpretation from foreign firms is not able to help us breaking through path dependence. In addition, the spillover effects of workers mobility is only significant at the level of new products launching, which implies that the immigrant scale of worker is small, and the workers are not in the top level.
