Taking China and the 10 ASEAN countries as the research objects, the social network analysis method was used to construct the China-ASEAN trade flow network, we analyzed the growth characteristics of the overall network, revealed the relationship and distribution rules of trade nodes, identified core-periphery roles, peer roles, and intermediary roles. The results show that: ①Singapore, Thailand, and China in the core circle have frequent interactions, and China gradually gain dominating status; countries in the semi-peripheral circle have frequent turnover and are not stable; Cambodia, Myanmar, Laos, and Brunei are always in the peripheral circle. ②The actors in the same trade flow network are redundant with each other in national resources, forming a strong competitive economic relationship. Brunei, Cambodia, Myanmar, and Laos have never acted as intermediaries. China, Singapore, and Thailand have acted as intermediaries far more often than other countries, and have more resources to control. Indonesia, Malaysia, Vietnam, and the Philippines act as intermediaries less often and lack the ability to utilize resources. ③China, Singapore, Thailand, and Vietnam can use redundant resources to explore existing trade gaps in the trade flow network, so as to gain more opportunities to explore new trade markets, and retain multiple options to avoid risks in a timely manner. Indonesia, Malaysia, the Philippines, Cambodia, Brunei and Laos lack redundant resources to diversify risks, lack trade intermediary capacity, and lack the ability to participate in the operation of trade flow networks. In order to narrow the partial development gap of China-ASEAN trade flow network and decentralize the power centers of China and Thailand; attach importance to the construction of trade flow sub-networks, connect Myanmar and Laos to the southwestern provinces of China, and shorten the distance between peripheral countries and key intermediary countries; With China and Singapore as strongholds, adjust the national trade layout and use the intermediary role to connect core and peripheral countries.
