| At present,international trade mainly focuses on maritime transportation,and container ports,as an important node of maritime transportation,connect all countries and regions in the world shipping network.The purpose of connectivity between container ports is to achieve win-win cooperation among countries and regions and jointly improve and develop the level of economy and trade.However,the number of container ports is large and the level of connectivity is uneven.At present,the research on the connectivity of container ports mostly focuses on the seaward.Therefore,based on the existing research,this paper puts forward the research on the sea land two-way connectivity of container ports.The purpose is to better reflect the connectivity level of container ports and promote the efficient development and construction of ports.Firstly,this paper summarizes the main ports in China’s five coastal port groups,and selects 8 main container ports from 19 main ports as the connectivity analysis object by using the method of cluster analysis.Secondly,combined with the analysis of the current situation and influencing factors of these container ports,and based on the theory of container port connectivity,this paper selects 18 connectivity evaluation indexes of China’s major coastal container ports.By using the method of factor analysis,this paper constructs the connectivity evaluation index system of China’s major coastal container ports,including 4 secondary indexes and 18 tertiary indexes,and obtains the weight of each index through calculation.Finally,using the method of evidential reasoning theory,this paper constructs the connectivity evaluation model of China’s coastal major container ports,processes the data of 18 indicators of 8 major container ports to obtain the basic attribute statistical table,and then uses the windows based Evidential Reasoning Intelligent decision-making system to calculate,and obtains the connectivity level ranking of China’s coastal major container ports.The results are Shanghai port first Shenzhen port is the second,Ningbo Zhoushan port is the third,Qingdao port is the fourth,Guangzhou port is the fifth,Tianjin port is the sixth,Xiamen port is the seventh and Dalian port is the eighth.At the same time,it can also analyze the advantages and disadvantages of each port,which can help each port formulate targeted measures when improving the connectivity level,hoping to provide scientific decision-making reference for the port construction in coastal areas of our country. |
