The development status and existing problems of the Beibu Gulf Port in recent years are evaluated. The implementation of the “One Belt，One Road”，the Western Development Drive，and other strategies is investigated. Then，we center around the “three major positioning” given by the state to Guangxi Autonomous Region and summarize the great strategic significance of building an international hub seaport and an international gateway for the new western land-sea corridor in the Beibu Gulf Port in the new development stage. According to the economic development situation of the hinterland，we analyze the future development demands of the Beibu Gulf Port and predict the future transportation demand scale of the port with the combined forecasting model. From the national strategic perspective，we put forward a development idea of “strengthening the hub，unblocking the corridor，cutting costs，improving services，and gathering factors” and build a functional system of “1 hub，2 networks，and 3 districts” for the Beibu Gulf International Gateway Port. Finally，we sort out the key tasks and relevant suggestions for the construction of the port in the near future，focusing on facility construction，improvement of collection and distribution channels，promotion of logistics services，and port industrial agglomeration. This research holds important guiding significance for the construction of international gateway ports in the future.
