Cross-border e-commerce platform, as a new type of trade intermediary, attracts a large number of small and medium-sized sellers to move in and promote the inclusive growth of global trade. Therefore, this paper focuses on the analysis of the theoretical mechanisms and typical facts behind cross-border e-commerce platform promoting the global inclusive trade development. We find that cross-border e-commerce platforms have obvious advantages in terms of trade costs, transaction procedures, model innovation and services trade. Global inclusive trade presents an all-round, multi-level and wide-ranging development trend. Global inclusive trade faces many internal and external challenges. Based on the above findings, further targeted policy recommendations are put forward.
