我国生产性服务进口对高技术制造业生产率的影响研究

t present, with the profound change of technological innovation, productive services, as the necessary intermediate inputs in the manufacturing process, play a very key role in the improvement of productivity of high-tech manufacturing. In order to explore the impact of the import of productive services on China\'s high-tech manufacturing industry, this paper studies the impact of the technical complexity of the import of productive services on the total factor productivity of high-tech manufacturing industry from the perspective of technical complexity, which is a measure of import quality. This paper first calculates the technical complexity of producer service imports and the total factor productivThe impact of producer service imports on productivity of China\'s high-tech manufacturing industryity of high-tech manufacturing industry in China from 2005 to 2018, and conducts an empirical study by using the analysis software Stata to analyze the relationship between the two from the overall and sectoral levels. The final results show that the technical complexity of producer service imports has a significant promoting effect on the improvement of the total factor productivity of high-tech manufacturing in China. Further analysis shows that different producer service imports have obvious industrial heterogeneity on the total factor productivity of high-tech manufacturing in China.
