Research On The Impact Of Digital Economy On Industrial Structure Upgrading In The Yangtze River Economic Belt

At present,the developed countries and leading regions in the world have successively regarded the development and expansion of the digital economy as an important strategy for the current regional sustainable development,so as to achieve the ultimate goal of revitalizing the real economy,promoting the transformation of the new and old economic power,and seizing the commanding heights and dominant position of development.Therefore,this paper has important research significance to study the effect of digital economy on industrial structure upgrading in the Yangtze River Economic Belt.Firstly,this paper first studies the impact of digital economy on industrial structure upgrading from the level of theoretical research,and analyzes the transmission path and transmission mechanism of digital economy to industrial structure upgrading,including the direct utility,indirect utility and spatial utility of digital economy on industrial structure optimization and upgrading.Secondly,this paper analyzes the development status of digital economy and industrial structure upgrading in the Yangtze River Economic Belt,and finally,the influence path of digital economy on industrial structure upgrading is empirically studied through the mediation effect model,and its spatial effect is explored empirically through the spatial Dubin model.The following conclusions are obtained:(1)Through its characteristics of high scientific and technological innovation,trade,urbanization level,high-tech talents and good government management,as well as its economies of scale,the digital economy can improve the scale and efficiency of factor market-oriented allocation,promote the process of factor marketization,and thus promote the upgrading of industrial structure.(2)The Moran’s I results of the spatial correlation test show that the industrial structure upgrading between the 11 provinces and cities in the Yangtze River Economic Belt has an obvious spatial positive correlation,that is,the industrial structure upgrading of the Yangtze River Economic Belt has spatial agglomeration.(3)The spatial Dubin model shows that there is a significant spatial spillover effect of industrial structure upgrading between regions.(4)The spatial Dubin model shows that the industrial structure upgrading between provinces and cities has a very significant spatial spillover effect.(5)The spillover effect of the digital economy on industrial structure upgrading has not yet been significant.Therefore,according to the research results,relevant suggestions are put forward: accelerate the process of economic integration,cultivate digital talents,give full play to the role of the digital economy in the optimization and upgrading of industrial structure,and improve the institutional system to ensure digital security.
