长三角港口群与城市群协调发展分析

Analysis on Coordinated Development of Port Cluster and Urban Agglomeration in Yangtze River Delta

摘要:

为研究长三角港口群与城市群协调发展水平，构建了长三角城市群经济发展质量和港口群发展水平评价指标体系，采用引力模型测算港口群内各港口对于城市群的辐射能力，在此基础上使用耦合度模型和耦合协调度模型衡量长三角港口群—城市群复合系统的协调发展水平，并测度了港口群各港口间协调发展水平用于分析港口竞合策略对于港口群—城市群系统协调水平的影响程度。研究结果表明，长三角地区已初步形成港口群—城市群协调发展的布局，正在向高水平的协调发展水平不断迈进。港口群向错位竞争、积极合作的发展方式转变能够提升港口群一体化协同发展水平，推动长三角高质量一体化发展。

Abstract:

In order to study the coordinated level of the port cluster and urban agglomeration， the evaluation index system of economic development quality of urban agglomeration and development level of port cluster in Yangtze River Delta region is constructed， and a gravity model is used to calculate the radiation capacity of each port in the port cluster to the urban agglomeration. On the basis of gravity model， a coupling degree model and a coupling coordination degree model are used to measure the coordinated development level of the Yangtze River Delta port cluster-urban agglomeration complex system， and calculate the coordinated development level of the port cluster which is used to analyze the influence of port co-opetition strategy on the coordination level of port cluster-urban agglomeration system. The results show that an initial coordinated layout has been formed between the port cluster and the urban agglomeration in Yangtze River Delta region， and it is moving forward to a high level of coordinated development. Besides， the trend that ports choose dislocation competition and active cooperation can enhance the level of integrated and coordinated development of port cluster and promote high-quality integrated development of the Yangtze River Delta.
