The China International Import Expo（CIIE）is playing an important role of the development of cross-border e-commerce as an open platform for China to share market opportunities with the world and an important window to foster a new development dynamic. Overall，the CIIE has been held for four consecutive sessions，but the direct promotion effect on cross-border e-commerce has not been significant. There are still restrictions on transforming CIIE exhibits into cross-border e-commerce commodities. In the future，the CIIE can be used to gather high-level entities，enhance the global resource element control capability of cross-border e-commerce，enhance the functions of key platforms，improve the cross-border e-commerce supply chain ecosystem that is linked online and offline，and promote the normalization of trade facilitation measures，help cross-border e-commerce meet diversified consumption needs，accelerate the transformation of exhibits into commodities，and fully release the spillover and driving effects of the CIIE in promoting the development of cross-border e-commerce.
