Research On Coordinated Development Of Port Logistics And Urban Economy Based On VAR Model

The joint development of port logistics and urban economy is the objective requirement of regional economic and social development and an important way to improve port competitiveness.Each stage of development has its own characteristics.Only the coordinated development of port and city can promote integration.Then,how to realize the interaction between port and urban economy,and how to realize the resource consistency and benefit optimization will become the key research direction in the process of collaborative development.Firstly,this paper introduces the theory of interaction between urban logistics and urban economy.Secondly,the paper selects port throughput and port city GDP indicators,and applies VAR model to analyze the interaction between port logistics and city economy.On this basis,from the perspective of system,this paper constructs a collaborative model to study the collaborative development relationship between port logistics and urban economy,and takes Guangzhou as an example to analyze the degree of collaborative development.The results show that there is a long-term stable equilibrium relationship between port logistics and urban economy,and Guangzhou economy can significantly promote the development of Guangzhou port.The degree of coordination between Guangzhou port and urban economic system changes with time,and the degree of coordination keeps improving with time.In 2018,the economic development of Guangzhou port and urban system has reached extreme coordination.Promote the innovation of port logistics technology,broaden the port investment path,improve the construction of port logistics hardware facilities and improve government support,effectively promote the growth of port logistics throughput and urban economic growth.Finally,combined with the coordinated development level of port and city,the paper puts forward some suggestions to promote the coordinated development of port logistics and city economy.This paper expounds the collaborative development process of port logistics and urban economy,using VAR model to confirm the interaction between them,and through the collaborative model to study the dynamic degree of coordination between them.The research results can provide reference for the relevant policy makers and the benign interaction between port and urban economy,which has certain theoretical and practical significance.
