Research On The Status Of Overseas Container Port In The Liner Shipping Network

In recent years,with the continuous development of trade globalization,economic ties around the world have become increasingly close.Container transportation,with its low cost and large capacity,plays an important role in international trade.As the starting point in container transportation,container ports are also of great significance to economic and trade development,have now become the main place for countries or regions to participate in international trade.Therefore,it is very important to study the status of Overseas Container Ports in the complex world liner shipping network for China to carry out foreign trade and promote the development of related industries under the current complex international situation.In this regard,this paper conducts the following research:(1)According to the shipping capacity ranking of shipping companies,this paper selects the shipping schedule data of the top 10 liner shipping companies for three consecutive months,and then uses space-l model to build a complex network of liner shipping.On this basis,the paper divides the world liner shipping network into 16 shipping regions,and then analyzes the structural characteristics of liner shipping network with k-core analysis method.Finally,the paper uses complex network statistical characteristic indicators to analyze the topological characteristics of the liner shipping network.(2)Considering the port competitiveness,this paper combines the complex network centrality index with it.Degree centrality is the accessibility index of the port,which represents the number of direct routes between port and other ports.Betweenness centrality is a key indicator of the port,which represents the port’s berthing frequency and transit capacity.Closeness centrality is the convenience index of the port,which represents the convenience and spatial advantage of the port to other ports.Eigenvector centrality is the index of port correlation,which represents the navigation situation and correlation ability between port and other hub ports.Through this method,this paper measures the central index and then analyzes the unilateral capacity of the port.(3)In this paper,the comprehensive evaluation method of node importance in complex network is adopted,and the weights of six node importance indexes are determined by entropy weight method.The status of overseas container ports is comprehensively evaluated based on GC-TOPSIS model.Finally,the result provides reference for China to carry out foreign trade and the construction of foreign investment of shipping related enterprises.
