摘要
城市间经济关联结构是探寻区域经济非均衡协同发展路径的重要依据。研究发现:上海、苏南、浙北和皖西南地区城市经济关联非常密切;长三角城市群网络层级结构明显,上海、南京、无锡、苏州、杭州和合肥等城市是特征鲜明的支点城市;三省经济关联结构存在明显差异,江苏存在多个“次核心”城市,浙江城市间连通度高,安徽城市网络较为稀疏,但省内城市与合肥关联密切,且大部分需要通过合肥与省外城市发生关联;三省城市在经济要素流上的位置和功能不同,且三省城市间经济要素流动最短通道数量各异。
The inter-city economic connection structure is an important basis for exploring the path of non-balanced and coordinated development of regional economy.The results show that the economic connection among Shanghai,the cities in southern Jiangsu,northern Zhejiang and southwestern Anhui are very close.The Yangtze River Delta city cluster network has a clear hierarchy,and Shanghai,Nanjing,Wuxi,Suzhou,Hangzhou and Hefei are the fulcrum cities with distinct characteristics.There are obvious differences in the economic connection structure among the three provinces.There are many"subcore"cities in Jiangsu,the connectivity between Zhejiang cities is high,and the network of Anhui cities is sparse.But the cities in Anhui are closely related to Hefei,and most of them need to be related to the cities outside Anhui through Hefei.The cities in the three provinces have different positions and functions in the flow of economic factors,and the shortest passages of the flow of economic factors among the three provinces are different in number.
