中文摘要：

国际技术扩散是影响本地企业技术创新能力的重要途径。利用2003—2008年区域面板数据，实证检验不同类型的国际技术扩散对我国内资企业技术创新能力的影响，结果表明：竞争效应和外资研发溢出效应对我国低层次技术创新能力具有显著的正向作用，对高层次技术创新能力没有显著作用；外资企业生产本地化程度反映的模仿效应对我国内资企业高层次技术创新能力具有显著的正向作用，对低层次技术创新能力没有显著影响；购买国外技术对我国内资企业各个层次的技术创新能力具有显著的正向作用，但是对高层次技术创新能力的促进作用小于对低层次技术创新能力的促进作用。

英文摘要：

International technology diffusion is the important path to influence the improvement of technical innovation ability of the local enterprise. By making use of the regional panel data from 2003 to 2008, this paper conducts an empirical test on the impacts of different types of international technology diffusion on the technological innovation ability of the domestic enterprises. The results show that the competition effect and the spillover effect of foreign R＆D have significant positive im- pact on China＇ s lower level technological innovation capability, while no significant impact on the higher level technological innovation ability. The imitation effect reflected by the degree of localized production of foreign-funded enterprises has significant positive effect on the higher level technological innovation capability of the domestic enterprise, while no significant effect on the lower level technol- ogy innovation ability. The purchase of foreign technology has significant positive effect on the technical innovation capability at all levels of the domestic enterprises, but the positive effect on the higher level is smaller than that on the lower level.
