Digitalization Input And Manufacturing Export Product Quality: Theoretical Mechanisms And Chinese Experiences

In the context of economic globalization,China has continuously expanded the international market through its own advantages,and the scale of foreign trade has increased rapidly and has become a major exporter in the world,of which the manufacturing industry occupies a major share.There is still a big gap,the overall competitiveness is weak,and the internal and external environment fluctuates,and exports are beginning to face ceiling constraints.It is urgent to explore and cultivate new advantages in export competition.With the advent of the era of information and big data,the integration and development of the digital economy and the real economy has become a new opportunity for industrial transformation and upgrading.As the main battlefield,the manufacturing industry should seize this opportunity and use digital investment to promote product quality upgrades and realize trade.sustainable development.Based on the above background,this thesis conducts an in-depth discussion on the issue of investing in digitalization to enable the transformation and upgrading of manufacturing export trade.First,on the basis of constructing an endogenous decision model of export product quality,this thesis explores the theoretical mechanism by which input digitalization affects export product quality,and analyzes the possible action paths.Secondly,referring to the existing research methods,using WIOD input-output table,Chinese industrial enterprise database,Chinese customs database and other data to measure input digitization and export product quality,in order to measure the input digitization level and export product quality level of China’s manufacturing industry.reality check.Afterwards,an econometric model is constructed to empirically test the effect and mechanism of input digitization on the quality of manufacturing export products.Finally,based on the above analysis,the main research conclusions of this thesis are extracted,and relevant policy suggestions are put forward accordingly.According to the above research ideas and methods,this thesis finds that:(1)There are inter-period and cross-sectional development differences in investment digitization and manufacturing export product quality.In terms of investment digitization,the overall trend is fluctuating and rising,and the degree of investment digitization in technology-intensive industries The highest,followed by capital-intensive and labor-intensive industries.The overall quality of export products of manufacturing enterprises also fluctuates over time,and the quality of export products of labor-intensive industries is higher than that of capital-intensive and technology-intensive industries.Foreign-funded enterprises export products.The quality is higher than that of state-owned enterprises and private enterprises;(2)The basic regression results show that investment digitization can significantly improve the quality of manufacturing export products,and the results are still stable after replacing the main variable measurement methods,variable measurement dimensions and solving endogeneity problems(3)After the introduction of heterogeneity regression analysis,it is found that at the level of industry heterogeneity,the promotion effect of investment digitization on capital-intensive,labor-intensive,and technology-intensive enterprises decreased in turn;at the level of ownership heterogeneity,investment digitization The promotion effect on private enterprises is higher than that on foreign-funded enterprises,but there is no significant promotion effect on state-owned enterprises;in terms of the heterogeneity of trade modes,digitalization has a significant positive impact on the product quality of general trade and processing trade enterprises,and general trade is higher than processing trade;(4)Through the regression and test of the mediation effect model,it is found that the impact of input digitalization on the quality of export products has two channels: production efficiency and quality production capacity,and the two have the same direction.To sum up,this thesis discusses the theoretical mechanism by which digital investment affects the quality of manufacturing export products on the basis of the existing literature,and conducts empirical tests in various aspects based on this,which is a further enrichment and supplement to the current research,and also It provides reasonable inspiration for the high-quality development of China’s manufacturing industry in the digital economy era,cultivating new advantages in the international competitiveness of the manufacturing industry,and promoting the construction of a trade power.
