Research On Impact Of Heterogeneous R&D Investment On GTFP

The report to the 19th national congress of the communist party of China pointed out that innovation is the primary driving force for development and the strategic support for building a modern economic system.As the focal point of national innovation,research and development investment plays an important role in improving regional total factor productivity and building a modern economic system.It is found that there are some differences in the internal structure of R&D investment in the three regions of east and west China,which have different influences on the development of GTFP.Starting from the internal structure of R&D investment,this paper explores the heterogeneity of R&D investment intensity,R&D investment scale and different fields of R&D investment in three regions of China.The Malmquist-Luenberger index was calculated by using SBM model to measure the green total factor productivity of 30 provinces and cities from 2005 to 2017,and the impact of heterogeneous R&D investment on green total factor productivity was studied by regions.The research conclusion shows that,firstly,the increase of R&D investment intensity can significantly promote the increase of green total factor productivity in various regions.Over the years,due to the high level of research and development investment,the eastern region has formed a good research and development environment and has a mature scientific and technological innovation capacity.Increasing the intensity of research and development investment can further realize the improvement of total factor productivity.Second,the increase of R&D investment scale can also significantly improve the total factor productivity of green areas.Due to the relatively low level of research and development in the western region,there is more demand for research and development practitioners.Increasing the scale of research and development practitioners in the western region is conducive to improving the internal structure of personnel,and the improvement of green total factor productivity in the region is more obvious.Third,three different regions in the field of R&D work individually,green total factor productivity to the region are showing positive role in promoting,and when the three common role in regional development,played a significant role in applied research and experimental development investment,and have the effect to curb investment in basic research,analysis of the reason may be that in the low level of basic research investment,with the other two studies investment proportion is still not perfect,needs to increase investment in basic research in various areas,investment proportion adjustment in various areas,play a role of leading source of the development of basic research.
