| Since the 18 th CPC National Congress,the value added of China’s manufacturing industry has grown from 16.9 trillion yuan in 2012 to 33.5 trillion yuan in 2022,increasing its global share from 22.0 percent to 29.5 percent.China has become the world’s largest manufacturer.However,although China has become the "factory of the world",it is still not a manufacturing power.China’s manufacturing industry still suffers from such problems as low technological content of its products,a big gap between its technological level and that of developed countries,and weak international competitiveness.As an emerging economy,digital economy has played an important role in enhancing industrial competitiveness and promoting technological innovation.The digital economy has provided an opportunity for the manufacturing industry to move from "made in China" to "created in China".In this context,it is all the more important for China to seize the opportunities of the development of the digital economy,promote high-quality development of the manufacturing industry and enhance its international competitiveness.Therefore,based on the macro perspective of digital economy,this paper analyzes its impact on the international competitiveness of manufacturing industry,in order to provide reference for the future development direction of China’s manufacturing industry.Firstly,in this paper,the measurement of the digital economy,the measurement and influencing factors of the international competitiveness of the manufacturing industry and the related literature of the impact of the digital economy on the international competitiveness of the manufacturing industry are reviewed.Secondly,this paper measures the international competitiveness of China’s digital economy and manufacturing industry and analyzes the current situation.Thirdly,this paper proposes that digital economy can enhance the international competitiveness of manufacturing industry by reducing trade costs,promoting technological innovation and enabling green development.Fourthly,based on the panel data of 31 provinces and cities in China from 2010 to 2020,the evaluation system is constructed to measure the digital economy,and the international competitiveness of the manufacturing industry is measured by the index of RCA,and the overall evaluation,as well as the dimensional and regional evaluation is conducted.Finally,in the empirical analysis,the two-way fixed effect model is constructed to analyze the impact of digital economy on the international competitiveness of manufacturing industry.In order to further reveal the influence mechanism of digital economy on the international competitiveness of manufacturing industry,a mechanism effect model is constructed to discuss the mechanism effect of digital economy on the international competitiveness of manufacturing industry.In the heterogeneity test,the heterogeneity of the digital economy on the international competitiveness of manufacturing industry is innovatively analyzed based on different dimensions.The endogeneity problem is discussed by using two-step system generalized moment estimation,and the results are still valid after robustness test.Based on the calculation of digital economy and the international competitiveness of manufacturing industry in China,as well as the theoretical and empirical analysis of the influence of the former on the latter,this paper draws the following conclusions:firstly,the level of digital economy and the international competitiveness of manufacturing industry in China have been improving year by year,showing a good development trend and potential,but there is a problem of inter-regional development uncoordinated.Secondly,digital economy has a significant positive effect on the international competitiveness of manufacturing industry,but there is regional heterogeneity,industry heterogeneity and segmentation dimension heterogeneity.Based on the four subdivision dimensions of the digital economy,this paper analyzes its heterogeneous impact on the international competitiveness of the manufacturing industry,and draws the conclusion that the development level of digital infrastructure has the greatest promoting effect on the international competitiveness of the manufacturing industry.Thirdly,digital economy can enhance the international competitiveness of manufacturing industry through three mechanisms: trade cost reduction,technological innovation and industrial green development.Based on the above conclusions,this paper puts forward four recommendations:(1)Build the manufacturing Internet platform to realize the interconnection of manufacturing enterprises in different regions.(2)Cultivate digital talents,narrow the gap in the development level of digital economy in different regions,and form a "talent dividend".(3)Accelerate the construction of digital infrastructure,tamp the base for the development of digital economy,and maximize the effectiveness of digital economy in enhancing the international competitiveness of manufacturing industry.(4)Standardize the standards for green development of the industry,encourage technological innovation,provide effective institutional environmental protection,and better play the role of digital economy in enhancing the international competitiveness of the manufacturing industry through such mechanisms as green development and technological innovation. |
