Empirical analysis of the contribution rate of science and technology innovation based on inter-provincial panel data——Analyzing the impact of scientific and technological inputs
Science and technology innovation capability is the core element of a country's comprehensive strength and competitiveness,and is the core driving force of economic growth and social development.The role of science and technology investment in promoting economic growth is indisputable,and although the level of science and technology innovation and the intensity of science and technology investment in China are increasing year by year,their intensity is still low compared with that of developed countries.Based on the panel data of 30 provinces in mainland China(except Tibet)from 1990 to 2019,this paper introduces science and technology input factors into the production function on the basis of the Cobb-Douglas production function;and through the economic growth accounting theory,we compare and analyze China's investment in science and technology from the Tenth Five-Year Plan to the Thirteenth Five-Year Plan from the time dimension.The results show that:(1)the economic growth of China's provinces during the period from the Tenth Five-Year Plan to the Thirteenth Five-Year Plan has been boosted by the investment in science and technology and the contribution rate of science and technology innovation.The empirical results show that:(1)the pull rate of science and technology investment to economic growth varies greatly among provinces in different planning periods.(2)The contribution rate of science and technology innovation of each province in different planning periods shows different characteristics.(3)The greater the amount of science and technology investment,the higher the contribution rate of science and technology innovation,and the two are directly proportional to each other.And according to the investigation results,some relevant suggestions are put forward:each province should further improve the science and technology investment,promote the transformation of science and technology industrial structure,etc.to finally achieve the purpose of promoting economic growth.
