摘　　要：本文旨在剖析城市经济效能空间联系网络的特性与模式,以期为区域一体化提供新的政策洞见。从标度律视角构建理论框架探讨城市间的经济效能空间联系,建立了反映网络外部性的分析范式。以长三角城市群为案例区,运用改进的引力模型和社会网络分析方法,测算城市经济效能,分析城市间的联系强度,并建立空间联系矩阵。研究发现:①长三角城市群的高经济效能区域由东部高等级城市向西北部低等级城市逐步转移;②高等级城市在网络中占据核心地位,与周边城市形成紧密联系和“小群体”结构;③城市组群联系模式中,沪苏、杭甬和合肥组群呈现双中心辐射型与虹吸型共存,而南京组群则为单中心辐射型。这4个组群中城市间的联系路径相对固定,联系模式演变缓慢。这些结果为理解城市群内部的联系动态提供了新视角,并为长三角城市群的协调一体化发展提供了政策参考,具有重要的理论价值和现实意义。This paper aims to examine the characteristics and patterns of the spatial linkage networks of urban economic efficiency so as to provide new policy insights into the regional integration process.The study builds a theoretical framework to analyze the spatial linkage of urban economic efficiency among cities from the perspective of scaling law.It constructs an analytical paradigm to reflect the network externalities.The Yangtze River Delta Urban Agglomeration(YRDUA)is selected as a case study,and the improved gravity model and social network analysis are applied to measure the urban economic efficiency from 2000 to 2020,analyze the strength of inter-city linkages,and construct a spatial linkage matrix.The results reveal that:(1)the high economic efficiency zone of the YRDUA is gradually shifted from the high-grade cities in the east to the low-grade cities in the northwest;(2)the high-grade cities occupy a central position in the network,forming solid links and"small groups"with the neighboring cities;(3)in the linkage pattern of the urban agglomeration,the Shanghai-Suzhou,Hangzhou-Ningbo,and Hefei clusters show a dual-center,radiation-type and siphon-type coexistence.In contrast,the Nanjing cluster shows a single-center radiation pattern.The linkage paths of the cities in these four clusters are relatively fixed,and the linkage patterns evolve slowly.These findings coincide with the theory of city"quality"in urban geography and the theory of city links in economic geography,and provide empirical support for the integrated and coordinated development of the YRDUA,as well as emphasize the importance of the coordinated development pattern of the"wild goose"echelon structure,which is essential for the understanding of the development of the YRDUA.
