Against the background of the accelerated digitalization process of the global economy, the impact relationship between digital transformation and international trade has become a part of economic development that cannot be ignored. This paper takes the multiple regression model analysis method and hierarchical analysis method as research tools to further explore the role of digital transformation on the country’s international trade path. After clarifying that “Internet Plus” can promote the innovation of international trade model, change the way of international trade information dissemination and improve the efficiency of international trade transactions, 10 developing countries of RCEP organization countries are selected as research objects. At the same time, the export trade volume (EX) is selected as the explanatory variable, and the level of industrial digital transformation (DT) is the core explanatory variable, and the relationship between digital transformation and national export growth and export trade scale is successively discussed. The effect of digital transformation on the country’s export growth is significantly positive (P<0.001), indicating that digital transformation is an important wind for developing international trade in developing countries.
