Research On The Coordinated Development Of Logistics Between Ports And Port Cities In The Yangtze River Economic Belt

As an important engine to drive economic growth in the hinterland,ports have become an important part of the global logistics network.As the hub of the supply chain,the port has a direct and close relationship with the logistics development of the city.The logistics development of port cities will have an impact on the operation mode and efficiency of ports,and then affect the comprehensive strength of ports;The improvement of port infrastructure brought about by the improvement of port capacity and the advantages of industrial agglomeration formed in port areas will bring corresponding logistics demand to port cities,thus making port city logistics activities more prosperous.This paper studies the coordinated development relationship between ports in the Yangtze River economic belt and port city logistics.The main research contents are as follows:Firstly,it expounds the research background,significance,content and relevant research methods of this paper.On the basis of extensive reference to relevant literature,it uses the port economic contribution theory,industrial agglomeration theory and system synergy theory to make a theoretical explanation for the relationship between port and port city logistics,and discusses the interaction mechanism between port and port city logistics from four aspects: port city,collection and distribution,information and policy support;Secondly,the evaluation model of port competitiveness is constructed,and the development status of the main ports along the Yangtze River economic belt is introduced,and the competitiveness of the above ports is evaluated by using the entropy weight TOPSIS method;Then the evaluation index system of urban logistics competitiveness is established,and the logistics competitiveness level of the main port cities along the Yangtze River economic belt is measured by using the entropy weight TOPSIS method;The last part is the empirical analysis of the logistics coordination degree between ports and port cities in the Yangtze River economic belt.According to the calculated evaluation values of port competitiveness and urban logistics competitiveness,firstly,a panel vector autoregressive model is established to measure the impact relationship between the two as a whole.Secondly,the coupling coordination degree is analyzed to further explore the relationship between port and port city logistics.The results show that:(1)the size of port competitiveness is closely related to the development scale of port cities.In the competitiveness ranking of ports along the Yangtze River from 2010 to 2019,Chongqing port,Nanjing port,Wuhan port,Changsha Port and Hefei port have always been in the top five.(2)Urban logistics competitiveness is closely related to urban development scale and urban economic volume.The level of logistics competitiveness of provincial capital cities is much higher than that of non provincial capital cities.Among the port cities along the Yangtze River from 2010 to 2019,Chongqing,Wuhan,Nanjing,Changsha,Hefei and Nanchang have always ranked among the top six in terms of urban logistics competitiveness.(3)The results of panel vector autoregressive model show that the growth of port area has a significant positive impact on the development of port city logistics,but the impact of the development of port city logistics on port area is relatively small.(4)The analysis results of the coupling coordination degree model show that the coupling coordination degree of port and port city logistics is affected by the port system and port city logistics system.From the perspective of spatial distribution,the degree of coupling and coordination between ports and port cities in municipalities and provincial capitals is significantly higher than that in non provincial capitals.
