依据1991～2007年我国各省市区数据,对自主研发、国际技术扩散与生产率的关系进行了实证分析。研究发现,从全国来看,自主研发、输入型FDI和进口贸易对生产率有显著促进作用,但国外专利申请对生产率没有显著影响;从东中西部地区的比较来看,自主研发对生产率都有显著正效应,FDI只对东部地区的生产率有显著正效应,进口贸易只对中西部地区的生产率有显著正效应,而国外专利申请对东中西部生产率都没有显著影响。
Based on the data of various provinces and cities in our country from 1991 to 2007, this paper empirically analyzes the relationship between independent research and development, international technology diffusion and productivity. The study found that, from a national perspective, independent research and development, import-oriented FDI and import trade have a significant role in promoting productivity, but foreign patent applications have no significant impact on productivity. Compared with the eastern, central and western regions, independent research and development have a positive impact on productivity Significant positive effect, FDI has a significant positive effect on the productivity of the eastern region, import trade has a significant positive effect on productivity in the central and western regions, while foreign patent applications have no significant effect on the productivity of the eastern, central and western regions.
