| Foreign direct investment is an elemental output that integrates capital,production technology,management technology,and marketing methods,and is an important source of direct capital output and indirect technological spillovers.The spillover effect brought by the use of the externalities of foreign direct investment is an important way for China to develop technological progress,optimize its industrial structure,and promote economic growth.Since the 1980 s,with the optimization and integration of industries across the world and the rapid development of the service liberalization process,the service industry has become the world's largest investment area,and the FDI of the producer service industry has also become the industry of developed countries to developing countries.The important mode of transfer means that international industrial transfer is evolving to a higher level.China,as the largest developing country in the world,also undertakes and absorbs more FDI in the productive service industry.Then,is there any technological spillover in the research into the inflow of FDI in the producer service industry and the introduction of productive services in China? Whether or not FDI has the ability to absorb technological spillovers deserves a profound discussion.After reading a large amount of relevant literature,this article has drawn a technical spillover mechanism concerning FDI in the producer services sector,mainly including secondary school effects,competition effects,model imitation effects,and correlation effects,and summarizing the effect of absorptive capacity on FDI technology spillovers mechanism.Since the provincial panel data is used in this paper,regional absorption capacity indicators are selected,which mainly include five absorption capacity indicators: economic development level,human capital,infrastructure,foreign trade dependence,and service industry development level.In the empirical part,we first construct the FDI technology spillover regression model for producer services and carry out an overall regression and group regression of the East,Central,and West.The results show that there is no obvious technical spillover in China's overall FDI of producer services,but in the grouping regression.There is a clear technical spillover in the eastern region,and there is no obvious technical spillover in the central region.There is a negative technological spillover in the western region.Then,a threshold model of absorptive capacity was constructed to perform threshold check and threshold effect regression,and the five levels of thresholds for economic development level,human capital,infrastructure,foreign trade dependence,and service industry development level were calculated.Research shows that there is a single threshold effect on the level of economic development and infrastructure,and there is a double threshold effect on the level of human capital,dependence on foreign trade,and development level of service industry.According to the threshold,the provinces of our country are divided,and it is found that there are obvious differences in the absorptive capacity of the eastern,central and western regions.The absorptive capacity of the central and western regions is relatively weak,and the absorptive capacity of the eastern region is better.Finally,there are problems in the absorption capacity of China,put forward corresponding countermeasures and suggestions. |
