Research On The Impact Of Digital Economy On Manufacturing Upgrading

Digital economy is a new economic and social form.The recent years have witnessed the rapid development of it.Nowadays,digital economy has become a new engine for the transformation and upgrading of economy,as well as the keypoint of international competition.At the same time,China’s manufacturing industry is still facing the challenge of "squeezing at both ends".It is urgent to seek new driving forces for improving quality and efficiency and shaping new international competitive advantages.Under such circumstances,the vigorous development of digital economy provides a good opportunity for the upgrading of China’s manufacturing industry.Empowering the upgrading of manufacturing industry through the development of digital economy has great strategic significance for China to achieve high-quality development,build a modern economic system and enhance international competitiveness.On the basis of sorting out and summarizing relevant theories and literature,firstly,this dissertation defines the theoretical connotation of digital economy and manufacturing upgrading,and discusses the impact mechanism of digital economy on manufacturing upgrading from three aspects: direct effect mechanism,indirect transmission mechanism and spatial spillover effect.Secondly,based on the actual data,this dissertation establishes the comprehensive evaluation index system of digital economy from the three dimensions of digital infrastructure,digital industry and digital integration,and establishes the comprehensive evaluation index system of manufacturing upgrading from the four dimensions of efficiency,structure,profitability and environment.It measures and analyzes the development status of China’s digital economy and manufacturing upgrading respectively.Then,this dissertation constructs benchmark regression model,intermediary effect model and spatial econometric model respectively,and empirically tests the effect and mechanism of digital economy on China’s manufacturing upgrading from multiple angles.According to the results of empirical analysis,this dissertation puts forward measures and suggestions from the aspects of improving digital infrastructure construction,optimizing the allocation of resources,building regional collaborative network,and creating a good innovation environment.The main conclusions of this dissertation are as follows:(1)The development level of digital economy and the upgrading level of manufacturing industry show an overall upward trend,both in China as a whole and in every province,but their development shows heterogeneity in different provinces and regions.(2)The development of digital economy has a significant positive impact on the upgrading of manufacturing industry,and this impact shows regional heterogeneity.(3)The incentive function of innovation is the intermediary mechanism of digital economy promoting the upgrading of manufacturing industry.(4)The impact of digital economy on manufacturing upgrading has a positive spatial spillover effect.(5)Digital economy has a significant positive spatial spillover effect on the intermediary mechanism.At the theoretical level,this dissertation expands the research perspective of manufacturing upgrading,comprehensively discusses the effect and mechanism of digital economy empowering manufacturing upgrading from multiple angles,and enriches the relevant research.At the practical level,it provides useful enlightenment on how to effectively play the role of digital economy to promote the upgrading of China’s manufacturing industry.
