To expand the source of goods，smoothen the passage of goods and improve the level of goods is of great importance towards building the national logistics hub of Beibu Gulf gateway port，build a new passage of land and sea in western China and construct a new development pattern of “double circulation”. Based on theoretical construction，model analysis，SWOT analysis and other methods，this report conducts in-depth research on the hinterland of Beibu Gulf gateway port，channel network，and the integrated development of Hong Kong-industry-city. First，the port hinterland continued to expand，initially formed a circle structure with Guangxi as the gateway hub，leading the four provinces and one city in southwest China，and radiating the “13+1” provinces，autonomous regions and cities in the west. However，the competition of Xijiang Waterway and the lack of key passageways made the fan-shaped hinterland degenerated into a crescent，and the port hinterland was located in a corner，and the expansion was weak. Second，the construction of passageways has been improved，the sea route network has been further enriched，and the sea-rail combined transport network has been steadily expanded，forming a two-way pattern of openness and mutual promotion. However，the key passageway nodes are nearly saturated，and the passageway network is not well connected，and the system is not yet complete. Third，Hong Kong-industry-city integration and mutual promotion are taking shape. However，due to the overall low level of industrialization，urbanization and economic development，they are still interconnected，and it is difficult to foster new growth areas. Based on the above analysis，this report puts forward suggestions from four aspects：constructing industrial cooperation alliance，building China-ASEAN cooperation and development demonstration zone，unblocking comprehensive collection and distribution system，and improving port service efficiency，so as to effectively serve the expansion of goods source and channel improvement of Beibu Gulf gateway port.
