Study On The Interaction Between Port Logistics And Urban Industry

With the rapid development of global economic globalization,the means of production and various products flow around the world,the total international trade is expanding day by day,and the rapid development of port logistics is promoted.Under the background one belt,one road,the most coastal cities in China have put forward the strategic plan of "interaction between city and port" and "developing the city with Hong Kong".The rapid development of port logistics attracts the transfer of production factors to ports,leading to the rapid development of urban industry,and the development of urban industry provides supply guarantee for port logistics.Therefore,the positive interaction between port logistics and urban industry is very important for the development of port city industry.This paper studies the interaction between port logistics and urban industry,and takes Dalian as an example to make an empirical analysis.First,based on the relevant research results at home and abroad,the paper expounds the core concepts of port logistics and port city industry,summarizes the cargo structure and the classification methods of port city industry,then introduces the basic principles of relevant theories and methods,which lays a theoretical foundation for the subsequent research.Secondly,the relationship between port and city,port and city industry and port logistics and urban industry are analyzed;Then,the interaction between port logistics and urban industry is analyzed from the interaction between port logistics and urban industry.Thirdly,the index of grey correlation model is determined by selecting the index,the calculation steps of grey correlation model are introduced.The industrial types with high relevance degree of port logistics are selected by using the grey correlation model.Based on the grey correlation model,the index of vector autoregression model(VAR)is selected,and the calculation steps of the vector autoregression model are introduced,The paper analyzes the interaction between port cargo logistics and key industries in cities by using vector autoregression model(VAR).Finally,the paper takes Dalian as an example to make an empirical analysis.The article expounds the development status of the port logistics in Dalian and the key industries in the city.The industry with strong relevance degree with port logistics is obtained by establishing the grey correlation degree model;Then,the paper analyzes the interaction between port cargo logistics and key industries in the city by selecting typical examples with strong industrial relevance,and concludes that the rapid development of Dalian Petrochemical industry has a significant effect on the increase of the flow of petroleum and liquid chemicals,but the increase of the logistics volume of petroleum and liquid chemical industry has no obvious effect on the development of petrochemical industry;The rapid development of Dalian automobile manufacturing has a significant effect on the increase of the automobile flow in Dalian port,but the increase of Dalian Port automobile flow has no obvious effect on the development of Dalian automobile manufacturing industry.And the relevant development suggestions are put forward according to the conclusion.
