Research On The Impact Of Transportation Infrastructure And Digital Infrastructure On Industrial Structure Upgradin

China’s economy has entered a new stage of development.In order to achieve high-quality economic development and promote the effective improvement of quality and reasonable growth of quantity,it is necessary to change the mode of economic development and transform and upgrade the industrial structure.As the pioneer capital of social and economic development,infrastructure has a great influence on industrial structure.On the eve of the fourth scientific and technological revolution,digital technology and traditional transportation infrastructure have been deeply integrated,and the construction of transportation infrastructure and digital infrastructure has a far-reaching impact on the industrial structure.Therefore,it is of great significance to study the impact of the coordination of transportation infrastructure and digital infrastructure on the upgrading of industrial structure in order to explore how the two can be integrated and coordinated and how their coordination can affect the upgrading of industrial structure,so as to promote high-quality economic development.On the basis of combing the relevant literature and analyzing the industrial structure theory and synergistic theory,this study constructs the mechanism framework of cooperation between transportation infrastructure and digital infrastructure and the theoretical mechanism of their synergistic influence on industrial structure upgrading.Then,taking the data of 31 provinces(cities)in China from 2011 to 2020 as samples,this paper measures the related indicators of coordination between transportation infrastructure and digital infrastructure through entropy method and coupling coordination model,and finally makes an empirical study by using panel regression.The research results of this paper are as follows:(1)The coordination of transportation infrastructure and digital infrastructure has a significant role in promoting the upgrading of industrial structure.Among them,there is a negative linear relationship between linkage and coordination and the rationalization of industrial structure,and there is a positive linear relationship between linkage and coordination and the elevation of industrial structure;There is not only a linear relationship between coupling and cooperation on industrial structure,but also a positive U-shaped curve relationship on rationalization of industrial structure and an inverted U-shaped relationship on upgrading of industrial structure.(2)The coordination of transportation infrastructure and digital infrastructure indirectly affects the upgrading of industrial structure through the transmission channel of consumption upgrading effect.(3)The coordination of transportation infrastructure and digital infrastructure indirectly affects the upgrading of industrial structure through the transmission channel of resource allocation optimization effect.(4)The synergy between transportation infrastructure and digital infrastructure indirectly affects the upgrading of industrial structure through the transmission channel of technological innovation effect.
