Digital Technology Competition,Infrastructure and Domestic Value-added Rate of Enterprises'Exports
Digital technology competition has become the key for China to seize the commanding heights and dominance of global sci-ence and technology.It is of great significance for China to cultivate new advantages in international competition for China enter-prises to enhance the division of global value chain through digital technology competition.By comparing the digital transformation level of listed companies in China and the United States this paper explores the influence mechanism of digital technology gap at home and abroad on the domestic added-value rate of China enterprises exports,discusses the mechanism path of infrastructure construction affecting the value chain jump of digital transformation enterprises,and tests its influence mechanism by using the import and export data of listed companies in China from 2008 to 2016.It is found that the digital technology gap at home and a-broad is negatively correlated with the domestic added value-rate of China enterprises'exports,and it is found that the export do-mestic added-value rate of China digital transformation enterprises has not increased accordingly at this stage,and this conclusion still holds after a series of robustness tests and endogenous tests.The mechanism test shows that technological progress is positive-ly correlated with the domestic added-value rate of China enterprises'exports,and the weak product substitution ability and slow technological progress are the main reasons why China enterprises can not exert the economic empowerment effect of digital tech-nology.The expansion analysis shows that there is a significant positive correlation between the enterprises digital transformation in China and the centrality of enterprise trade network,which shows that the digital transformation enterprises have higher require-ments for infrastructure construction.The above findings will provide theoretical support for Chinese enterprises to participate in the new round of global scientific and technological competition.The article calls on high-tech enterprises to bravely participate in international competition and break the international blockade of cutting-edge technology and also suggests that the government continue to promote the construction of infrastructure facilities to help high-tech enterprises grow.
