本文首先就外资加强控股对五种技术溢出效应的影响进行了理论分析,特别是对外资控股比例提高如何影响技术溢出效应的机制进行了探讨。随后,以三期中国全国经济普查数据为基础,对外资控股权与技术溢出效应之间的关系进行了实证分析。主要结论如下:第一,从地区层面来看,外资控股比例提高有利于集聚性技术溢出,但是不利于竞争性技术溢出;从行业层面来看,外资控股比例变动与两种技术溢出效应之间是非线性型关系。第二,外资控股比例较高和较低的地区或行业,两种技术溢出效应没有显著不同。
This paper first makes a theoretical analysis on the influence of foreign investment on controlling five spillover effects, especially on how the increase of foreign shareholding affects the technology spillover effect. Then, on the basis of the data from the three national economic censuses of China, the author makes an empirical analysis of the relationship between foreign ownership and technology spillover effects. The main conclusions are as follows: First, from a regional perspective, the increase in the proportion of foreign ownership in favor of agglomeration technology overflow, but not conducive to competitive technology spillover; from the industry level, the proportion of foreign ownership changes and the two technology spillover effects Is a non-linear relationship. Second, there is no significant difference between the two technology spillover effects in the regions with higher and lower proportion of foreign ownership.
