Research On The Impact Of Digital Economy On The High Quality Development Of China’s Industry

China’s economy has changed from a stage of rapid growth to a stage of high-quality development.At present,there are problems in industrial development,such as insufficient innovation capacity,overcapacity,relatively extensive growth mode,and urgent need to improve quality and efficiency.In the face of the "industry 4.0",how to release the kinetic energy of the digital economy,and achieve high-quality industrial development has become an urgent problem to be solved.This paper combs and summarizes the literature related to digital economy and high-quality industrial development,clarifies the relevant theories of digital economy development,and deeply analyzes the positive impact of digital economy on high-quality industrial development and the potential obstacles of digital economy enabling high-quality industry.Considering the limitations of existing research on research regions and research variables,this paper conducts empirical research based on provincial panel data from 2010 to 2020.First,based on the new development concept,a comprehensive evaluation index system is constructed from five dimensions: innovation,structural optimization,green efficiency,international competitiveness,and social benefits to measure the level of high-quality industrial development in the region and analyze its spatio-temporal dynamic characteristics.Secondly,divide the digital economy industry and calculate the scale of the digital economy.Finally,the PSTR model and spatial Dubin model are constructed to study the regional heterogeneity,nonlinear characteristics and spatial spillover effects of digital economy on high-quality industrial development.The following conclusions are drawn:First,the overall level of high-quality industrial development is steadily rising,but the high-quality development of regional industries is uneven,showing a ladder like spatial development pattern.At the same time,high-quality industrial development has an urban linkage effect.Second,the scale of the digital economy is seriously polarized,and there is an obvious "digital divide".From the perspective of the development trend of the digital economy,the digital divide has narrowed slightly,and the overall scale of the digital economy has continued to expand.Third,the digital economy can promote the high-quality development of industry,which is characterized by regional heterogeneity and nonlinear dynamics.In terms of regional heterogeneity,the digital economy plays the largest role in promoting high-quality industrial development in the central region,followed by the eastern region,and the western region is not significant.In terms of non-linear characteristics,the promotion of digital economy on high-quality industrial development is characterized by increasing marginal effect.After the scale of digital economy breaks through a certain threshold,its promotion on high-quality industrial development will be amplified.Fourth,the digital economy has a significant role in promoting the high-quality industrial development of this region,but it has a negative spatial spillover effect on the high-quality industrial development of other regions.
