Research On Space Spillover Effect Of High-speed Railway Technology Innovation

With the rapid development of China's high-speed railway,China has realized the transformation from introducing foreign advanced technology to absorbing to achieving complete independent innovation.According to the government work report released in 2019,the high-speed rail network achieved innovation and development,adding 4,100 kilometers of high-speed railway operation,continuous innovation of high-speed rail technology,continuous improvement of the railway network,breaking the barriers to the flow of factors between regions,and providing areas along the line The economic level and related industries bring space spillovers.Through combing and summarizing the relevant theories and literature on technological innovation and spillover effects,this paper defines the spatial spillover effects of China's high-speed railway technology innovation,deeply analyzes the theory of spatial spillover effects of technological innovation,and explores China's high-speed railway technology.The mechanism of the innovative spatial spillover effect based on the previous theoretical analysis,the Spatial Dubin mechanism Model is used to analyze the spatial spillover effects of China's high-speed rail technology innovation and construction in 2010-2016 on regional economic growth,human capital and capital investment.The model introduces the time reciprocal matrix while adding the simple adjacent matrix,which indicates the technological innovation development of the high-speed railway,and compares the economic growth and the spillover of the factors before and after the opening of the high-speed railway.The results show that the high-speed rail has opened the economy of 26 provinces across the country.There is a positive spatial spillover effect on output,and there is a spillover effect on capital and labor.The spillover effect caused by the shortened transit time of high-speed rail opening is stronger than the economic effect brought by simple neighboring matrix.The output elastic value of capital is greater than that of labor.Output elasticity,so the impact of capital on economic growth should be more important.Finally,it proposes to further improve the railway management system;improve the innovation capability and form an innovation mechanism;strengthen the high-speed railway management system,expand the railway network construction,and build high-speed railway as a national brand.
