Abstract: In order to give full play to the important role of port logistics in supporting the integration of the city into the global supply chain system,and to promote the deep integration and development of port logistics and the city,this paper constructs a coupling and coordination model of the two systems of port logistics and urban economy and industry,selects the major inland river ports cities as the research sample,which are proposed in the Outline of the National Comprehensive Stereo Transportation Network Plan,calculates and analyzes the coordination of urban systems with different water systems,based on the statistical data from 30 port cities from 2009 to 2022,and puts forward targeted countermeasures and suggestions.The results show that during the study period,the two systems in other cities have good coupling degree,but the 2 cities including Guigang,Laibin show a downward trend of coupling degree,which reflects that most cities’ port logistics interacts with the urban industrial economic system.Only 6 port cities’ coordination degree of the two systems is greater than 0.5 such as Chongqing,Wuhan,Hangzhou,which reflects that most cities’ port logistics and industrial economy system have not yet realized the benign interaction,and the port city property integration degree is low.Cities with different water systems also show regular development characteristics.
