| Scientific and technological innovation as a national economy healthy and stable development of intrinsic motivation and evaluation of national important indicator of overall national strength,is the key to improve economic quality and competitiveness.Under the new normal of economy,China's economy demands growth from high speed to medium and high speed.At this stage,we should promote the upgrading of industrial structure and solve the deep-seated problems.The fundamental way to realize the "Chinese dream" lies in innovation.Our government has made technology innovation as a powerful engine of transition,demanding a big development in strategic emerging industries.As a representative of emerging industries,high-tech industry is an innovation-driven industry,and promoting scientific and technological innovation is the essence of improving the level of high-tech industry.The high investment and high risk characteristics of science and technology innovation restrict the further development of high-tech innovation.Therefore,the development of industry requires strong external force,and scientific and technological finance is the maximum external force support,in which the investment of research and development is an important part of science and technology.This paper divides the development of high-tech industrial science and technology innovation into two stages.According to ?the statistical yearbook of high technology industry?,the sources of R&D funds are divided into government input and enterprise input.In both government and enterprises,capital investment is made in high-tech industries.What is the efficiency of investment in different stages of high-tech industry?This research will take China's high-tech industry as the object and study the impact of R&D expenditure on the technological innovation ability of high-tech industries under different conditions.In addition,China has a vast territory,and there is a large difference between different economic regions.It is not enough to conduct research and analysis on a national scale.Therefore,according to the factors such as the degree of economic development,the level of economic openness and the degree of marketization,this paper divides the 29 provinces into the eastern,central and western regions(the current economic regions in China are divided into four regions,because the northeast region contains fewer provinces and cities,so this paper is divided according to the original economic regions).The paper studies the impact ofgovernment R&D funds and enterprise R&D funds on the technological innovation capacity of high-tech industries in the perspective of the development of high-tech industries in the whole and different economic regions of the country.On the other hand,after the regression of the panel model,we further use the threshold regression model to study the impact of R&D expenditure input on science and technology innovation in various regions,and study whether there is a non-linear relationship between the R&D expenditure input of different sources and the innovation capability of high-tech industries.In this paper,the following conclusions are drawn: first,the investment of government R&D funds will have a "guiding effect" on the investment of enterprise R&D funds.Under certain conditions,the increase of government R&D expenditure will increase the investment of enterprise R&D and increase the capital utilization rate of enterprise R&D funds.However,if the government's money is in trouble,it will also lead to a decline in the use of corporate funds;Secondly,It is that difference between the government 's research and development fund and the various stages of technological innovation in high-tech industry base on the national scope and the scope of different economic regions;Thirdly,there is a threshold effect between the government R&D expenditure and the technological output in different stages of the high-tech industry. |
