Research On The Industrial Growth Effect Of China's R D Related Spillover

Under the external environment where the world economic structure is rapidly reshaping and China 's low-quality development model at the cost of demographic dividends and sacrificing a beautiful environment is unsustainable,there is an urgent need to change the investment mode and growth model,and rely on innovation to drive industrial structure adjustment Upgrade to promote economic transformation and development.The Eighteenth National Congress of the Communist Party of China formally proposed an innovation-driven development strategy.The core of innovationdriven development is R&D.R&D and its spillover effects can greatly promote the increase of the knowledge stock of this industry and other industries,and then carry out technological innovation and product upgrades to make it dominant in the economic market,thereby driving the development of the industrial economy and ultimately promoting the industrial structure.upgrade.Therefore,China must increase its dependence on R&D activities to improve its independent innovation capabilities.So,does R&D have spillover effects? Can R&D and its spillover effect promote industrial growth? How to promote the optimization of industrial structure to achieve economic growth? What is its dynamic mechanism? Research on these issues is related to the future allocation of R&D resources among industries and the priority development of which industries will maximize R&D investment and utilization.It has important theoretical and practical significance.Based on Rostow's dominant industry theory,this paper believes that due to differences in industrial technology,the importance of R&D and resource constraints,R&D input cannot be evenly distributed among various industries,but concentrated on high industrial correlation,Among the leading industries with strong driving effect and new technology diffusion effect,after the leading industry obtains a new production function through R&D activities,it drives the economic growth of the non-dominant industry through the spillover effect to realize the structural optimization and economic growth of the overall industry.After combing and summarizing the relevant literature,most scholars indirectly study the impact of R&D on economic growth from the perspective of R&D input and output.Few scholars directly study the effect of R&D spillover on industrial growth,and few scholars consider industrial The impact of R&D spillover,and there is no sub-industry group to explore the mechanism of R&D's effect on industrial growth.Based on previous research,this paper considers industrial heterogeneity,studies from the perspective of industrial association,and explores the industrial growth effect of R&D related spillovers by industry group based on Rostow's dominant industry theory.Innovatively proposed to use the direct consumption coefficient matrix in the input-output table to represent industrial associations,and use the spatial measurement method to build the panel using the panel data of 36 industrial industries in China from 2013 to 2017 and the direct consumption coefficient of the 2017 input-output table The model explores the industrial growth effect of China's R&D related spillovers.Characteristic facts show that: First,China 's R&D expenditures are significantly concentrated in the leading industries and the industry has self-correlation,and the R&D industry is divided into four clusters according to the industry 's R&D investment correlation.Empirical research shows: First,the industrial growth effect of R&Drelated spillovers does exist,and there are three spillover channels.Second,the dominant industry and non-dominant industries respond differently to R&D-related spillover effects.The R&D spillover effect of the leading industry is the main reason for the R&D spillover effect of all industries,and the R&D spillover effect of the leading industry has a greater effect on the growth of the industry.Specifically,leading industry R&D mainly drives the economic growth of leading industries through horizontal correlation and forward correlation spillovers;leading industry R&D mainly drives the economic growth of non-dominant industries through horizontal correlation and forward correlation spillovers;non-dominant industry clusters have also produced R&D has a positive spillover effect but a small spillover,and R&D in non-dominant industries exerts a suppressive effect on the growth of other non-dominant industries through horizontal correlation and backward correlation.
