Study on the Impact of Digital Economy on the Competitiveness of Industrial Products in Countries Along the"Belt and Road"
By three dimensions:digital infrastructure,digital innovation environment and digital industry development,the evaluation system of digital economy development level is constructed,and the sample data of countries along the"Belt and Road"from 2010 to 2020 are employed to empirically test the impact effect and mechanism of digital economy development level on the competitiveness of industrial export trade.Firstly,the results show that the development level of the digital economy in the countries along the"Belt and Road"is conducive to improving the competitiveness of industrial export trade,among which the level of digital economy development has a greater promoting effect on high-competitive countries than low-competitive countries,and has the strongest promotion effect on the export trade competitiveness of machinery transportation products.Secondly,the level of innovation has an important intermediary effect on the impact of the digital economy on the export trade competitiveness of industrial products in countries along the"Belt and Road".Thirdly,the optimization of industrial structure can adjust the impact of the digital economy of countries along the"Belt and Road"on the competitiveness of industrial export trade.
