Research on the selections of dry port cooperation seaports based on SFA model

To effectively explore the cooperation benefits between dry ports and seaports, and explore the selection of cooperative seaports from the perspective of inland dry ports, a cooperative seaport selection model based on principal component analysis and stochastic frontier analysis methods was established. The model comprehensively considers four factors: port city support, socio-economic development level, transportation conditions, port hardware facilities. Calculate the ranking of cooperative seaports by calculating cost efficiency. Applying the model to the selection of dry ports in Handan City, it was found that Qingdao Port and Tianjin Port have better cooperation benefits with Handan City, which is consistent with the current situation of waterless port cooperation in Handan City and verifies the effectiveness of the model. In the future, cooperation can be extended to ports such as Lianyungang Port, Yantai Port, and Nantong Port. Propose relevant development suggestions based on the results. This article innovates from the perspective of dry ports, searching for cooperative seaports for inland dry ports, and providing new ideas for the development planning of inland dry ports.
