| Under the background of economic globalization,ports as an important trading node of comprehensive transportation of domestic and foreign goods trade have developed rapidly.Among the five coastal port groups in China,the Yangtze River Delta port group plays an irreplaceable role in promoting China’s economic development.However,with the rapid development of the ports in the port group,the port scale is expanding and the hinterland overlapping is becoming more and more serious.At the same time,due to the unclear division of the functions and levels of the ports in the port group,the homogenization competition in the port group becomes more and more intense.Under this background,it is necessary to provide a new theoretical method for the hierarchical positioning of the port group and provide strategies for the coordinated development of the ports.The main research work and contents of this paper are as follows:Firstly,this paper describes the background and significance of this study,and then combs the domestic and foreign research literature from the two aspects of port network and port group collaborative development,determines the research ideas and research methods of this paper,and expounds the relevant theories used and involved in this paper.Then it analyzes the general situation of the Yangtze River Delta region and introduces the development status of the main ports in three provinces and one city,and finds out the main problems of the port group in the Yangtze River Delta.Based on the route data of 33 main ports in the Yangtze River Delta port group,this paper analyzes the importance,closeness and connectivity of the network characteristics to the ports,and then combines with the actual situation of the main ports in the current situation of the port group,selects four indicators that can reflect the characteristics of the ports,and then analyzes the network characteristics of the network through cluster analysis The port nodes are divided into levels,and then positioning analysis is carried out.Finally,the multi-dimensional grey prediction model is used to analyze the collaborative development degree of the Yangtze River Delta port group based on business,and put forward suggestions for the coordinated development of the port group.Finally,it summarizes the shortcomings of the paper and prospects the coordinated development of the Yangtze River Delta port group.Figure seventeen table twenty-one reference fifty-three... |
