| As the rapid development of digital technology,extensive infiltration and application in various industrial fields can accelerate the reconstruction of the material basis of the economy and society,the human economy and society will change into a new phase of digital economy along the evolution path of technological innovation,industrial restructuring,integration and application and system reform.As a pillar industry in a country's economy,the manufacturing industry represents the level of industrial development in a country.It is also the leading force in the national economy and an important foundation for economic restructuring.In the digital economy background,the industrial integration of the digital economy and the manufacturing industry shows an irreversible trend.Therefore,the research which objectively and scientifically evaluates the status quo of the digital economy,the convergence between digital industry and manufacturing industry and the impact on the manufacturing industry has important theoretical and practical significance for the future economic development of China.At present,the academic research on this issue is focused on qualitative aspects,and is still in the exploratory stage with many deficiencies and gaps existing.This paper constructs the theoretical analysis framework,and on this basis,it quantitatively and contrastively analyzes the present situation of the digital economy in major global countries including China,and calculates the positive and negative degree of fusion.On the basis of the above research,this paper makes an empirical analysis of the effect of industrial integration on the industrial performance and the industrial structure in the digital economy.This article takes the technical economy paradigm,digital economy and industrial integration theory as the theoretical basis for the study.The technical and economic paradigm is a comprehensive theoretical framework of technological progress toward micro-enterprise behavior,mid-level industrial transformation and macro-economic system transformation.The digital technical and economic paradigm is a qualitative change of the traditional material and energy based technical and economic paradigm,break the limitations of traditional production factors on supply constraints of growth and promote the progress of human development from atomic processing to information processing.Digital technology makes digitization of elements and industries,and make penetration and application in various fields of economy and society to promote the industrial economy to the digital economy.Under the framework of digital technology and economy,digital information and data are the key factors of production.Digital technology innovation is the core driving force.The information and communication industry,the Internet,the Internet of Things and the mobile communications network together make up of the digital infrastructure.The integration between basic digital industries and other sectors and industries is the new character.Digital economy which reshape the economic development pattern forms.The growth and development of the digital economy and digital convergence will lead to the product integration,business integration,management integration and market integration among different industries or different industries in the same industry,change the competition and cooperation between the original enterprises,blur the industrial boundaries and the reshaping the industries border,and eventually form a dynamic process of industrial integration.This paper systematically reviews the status quo and experience of the digital economy development in major countries both at home and abroad.Based on the analysis of digital industry,the digital trade situation(including digital goods trade and digital service trade),the Value-added of digital industries,digital economy and innovation,and the relation between the digital industry and economy,this paper constructs a measure of the degree of positive and negative industry convergence between digital industry and manufacturing industry,and compares the positive and negative convergence degrees of China in the mainstream countries in the world.Subdividing the positive and negative levels of convergence in various industries in the manufacturing sector shows that there is a gap on the digitization level in the highly polluting industries between China and the leading countries.Through the correlation analysis,we found that the industrial correlation between the digital industry and manufacturing industry is as high as 0.86,which is strongly correlated.Principal component factor analysis is used to find the key influence factors of industrial integration on manufacturing industry performance: positive integration,negative integration,industrial structure,market openness and marketability.Using the principal component factor analysis method,the key influence factors of industrial convergence on manufacturing industry performance are positive integration degree,reverse integration degree,industrial structure,market openness,and marketization level.Quantitative analysis of the effect of industrial integration on manufacturing industry performance through the panel data fixed effect model.During the sample period,the reverse degree of integration,industrial structure and market openness are all significant positive correlations to industry performance,while the positive degree of integration and the level of marketization has a significant negative effect on industry performance.The reason why the positive degree of integration has an negative impact on the industrial performance may be due to the obstruction of the old paradigm.The infrastructure construction and system construction in the context of the digital economy do not match with the old industry,and it will take some time to reach a new equilibrium state.The high proportion of state-owned enterprises in the industrial structure will inhibit market vitality and corporate competitiveness and adversely affect overall industry performance.The robustness analysis of the benchmark regression further proves the conclusion of the benchmark regression.Through the theoretical model of industrial structure,it is found that the evolution of the overall manufacturing industry structure in China is in line with the general laws of industrial development,and the industrial structure has a tendency of heightening,and the state-owned enterprises have higher industrial structure than the national level.This paper builds a fixed-effects model of panel data to test the impact of industrial convergence on the industrial structure.The regression results show that during the sample period,reverse industry integration,R&D intensity,and nationalization rate are conducive to the optimization and upgrading of the industrial structure of the manufacturing industry.The effects of the industrial structure of industry groups are divided.Due to the differences in product and technology characteristics of group industries,the positive integration degree of labor-intensive industries and capital-intensive industries are significantly negative to the industrial structure.The positive integration degree of technology-intensive industries is significantly positive to the industrial structure.The influence of foreign direct investment on the industrial structure of the manufacturing industry is uncertain in the benchmark model.Through the regression of the group industrial model,it is determined that foreign direct investment has an adverse effect on the upgrading of the industrial structure of China's manufacturing industry.Finally,this paper constructs a strategic framework to promote industrial integration from the macro,meso and micro levels. |
