Research On The Impact Of R&D Investment On The Quality Of China's Economic Developmen

As China enters a new stage of development,enhancing its capacity for reform and innovation and continuously promoting high-quality economic development have become an important task in the modernization process.As an important factor of innovation and R&D activities,R&D investment plays an important role in economic development.This paper takes R&D investment and economic development quality of different regions in China from 2000 to 2019 as the research object,aiming to explain the impact of R&D investment on economic development quality and provide reference for the development of R&D industry and the improvement of economic quality through relevant research.First of all,on the basis of reading relevant literature,combined with the background of social development,this paper expounds the relevant contents of economic development,and explains the mechanism of the effect of R&D investment on the quality of economic development.Secondly,based on the data in China Statistical Yearbook and China Statistical Yearbook of Science and Technology,this paper compares and analyzes the current situation of R&D expenditure and personnel investment in China as a whole and in different provinces,analyzes the structure of R&D expenditure,and measures the efficiency of R&D investment in China.Then,according to the theoretical research content above,an economic development quality evaluation index system is constructed,including five first-level indicators,coordinated development,green development,opening to the outside world and achievement sharing,and 29 second-level indicators.The global principal component method is used to calculate the weight of economic development quality score and index system of all provinces and cities except Xizang from 2000 to 2019.In order to verify the reliability of the obtained data,entropy method is used to calculate the weight.Finally,the mean of the weight obtained by the two methods is used to calculate and analyze the economic development quality index.Finally,through the fixed effect model and spatial Dubin model,this paper empirically analyzes the impact of R&D investment and its components on regional economic development quality and spatial spillover effect.Through the panel fixed effect model,it is found that the intensity of R&D investment significantly promotes the economic development of the whole country and the eastern and central regions.The investment of R&D funds in basic research,applied research and scientific research institutions has different influences on the economic development quality of the whole country and the eastern,central,western and northeastern regions.From moran index and the Dubin model,economic development between the different provinces in China,there are significant positive spatial correlation R&D strength,funding for basic research and research institutions of research funding to neighboring provinces has a significantly positive role in promoting economic development;However,applied research and university fund investment have a hindering effect on the economic development of neighboring provinces,and the other variables do not show obvious externalities.
