| Science and technology innovations were the first motivation of economic growth,and the primary factor to push forward the high-quality development of the economy.The 14 th Five-Year Plan of Shijiazhuang City clearly proposes to strengthen innovation drive,further increase the contribution rate to the progress of science and technology,and increase the investment of research and experimental development(R&D)funds to promote scientific and technological innovation.At present,Shijiazhuang City is in the key stage of economic structure adjustment and industrial transformation and upgrading.In this context,it is of great significance to scientifically evaluate the contribution rate of scientific and technological innovation to the city’s economic growth and explore the main influencing factors of scientific and technological innovation contribution rate as well as the promotion path to accelerate the innovation-driven development of Shijiazhuang City.It can also provide a solid theoretical basis and empirical support for the formulation of science and technology policy,which has important theoretical significance and application value.Based on the theory of internal economic growth,this paper used the stock of R&D capital as an index to measure the contribution rate of scientific and technological innovations,and put it into the economic growth accounting system,so as to establish a model to measure the contribution rate of scientific and technological innovations.PIM method and BEA method are used to estimate fixed capital stock and R&D capital stock respectively.The output elasticity of capital,labor and scientific and technological innovation factors is calculated by using error correction model,and the contribution rate of scientific and technological innovation to Shijiazhuang’s economic growth from 2000 to 2021 is finally estimated.Using fs QCA method,the configuration model of S&T innovation contribution rate was constructed,and the influencing mechanism of human capital,S&T input,government support,economic development,trade openness and factor endowment on S&T innovation contribution rate was discussed.The results show that scientific and technological innovation has become the first driving force of economic growth in Shijiazhuang City.In 2021,the scale of R&D capital stock in the city has reached 17.1 billion yuan,and the annual contribution rate of scientific and technological innovation is as high as 42.62%,showing a trend of steady rise.During the period from the 15 th to the 11 th Five-Year Plan,the city’s contribution rate of scientific and technological innovation increased at a high rate,with an average annual growth rate of 1.99%.From the 12 th Five-Year Plan period to the 13 th Five-Year Plan period,the contribution rate of science and technology innovation decreased significantly,with an average annual growth rate of 0.22%.There are three driving paths to realize the contribution rate of high-tech innovation,which can be summarized into three configurations: overall driving type,internal and external integration type and technology-oriented type.Among them,the investment in science and technology,human capital and open trade were the key factors to increase the contribution rate of science and technology innovations;The government’s support,the level of economic development,and the talent of factors were the sufficient and unnecessary conditions to increase the contribution rate of science and technology innovations;Besides,there was a potential substitute between the government’s support and the opening of trade.Based on the above research,this paper put forward four suggestions: to strengthen investment in technology and human capital,to improve the level of innovations,to expand the opening level of trade,and to promote the transformation of achievements,which provided reference to the government’s micro control. |
