Currently,the digital economy has become a key variable affecting the development of the world economy.However,most studies on measuring the digital competitiveness of individual countries rely on macro indicators such as the size of the digital economy,and digital development indexes composed of indicators such as the Internet penetration rate and the number of cell phones per capita.In this article,we measure the digital com-petitiveness of countries from the new perspective of'country-product'dual-mode trade network,rel-ying on the 209 HS-coded products corresponding to the core industries of the digital economy,and construct two indicators of the centrality of digital products and the complexity of digital trade,and find that China and South Korea are among the world's leading countries in the two indicators re-spectively.Then this article uses the digital trade complexity indicator to construct an empirical anal-ysis model,and through the robustness test,it is concluded that digital competitiveness has a signifi-cant role in promoting the economic growth of each country.Finally,this article explores the heteroge-neity of the impact of digital competitiveness on countries at different income levels and in different regions,and finds that digital competitiveness has a more obvious role in promoting economic growth in countries with higher income levels.
