摘　　要：基于生产性服务企业内部组织的关系型数据,从联系、节点、类型3个方面对长江中游城市群空间关联网络演变特征进行解析,在此基础上揭示影响城市群网络演变的主要驱动因素。结果表明:长江中游城市群处于以快速拓展网络联系覆盖范围为主的初级阶段,并逐渐呈现出轮轴状空间形态特征;空间关联网络结构层级化集聚态势明显,且网络节点数量和强度中心度分别呈现出清晰的“金字塔型”和“倒梯型”的结构特征;综合考虑各研究单元在网络中的相对联系规模和主导联系流向,可将研究单元分为网络流出活跃区、均衡活跃区、网络流入活跃区以及非活跃区4种类型,且空间分异格局日益清晰;市场力量、政府力量和技术力量等因素共同驱动着长江中游城市群空间关联网络的时空演变。Based on 2000,2009 and 2018 producer services firms’database of city clusters in middle reaches of the Yangtze River(MRYR),this paper measured and characterized the evolving features of spatial correlation network,including linkages,nodes and types.It further attempted to investigate the main influencing factors from several aspects.The findings of the study are as follows.Firstly,spatial correlation network of city clusters in MRYR is still at an early stage,which is characterized by rapidly expanding network coverage.Inter-urban linkages gradually appear a wheel-axle spatial form;network nodes of city clusters tend to agglomerate by hierarchy.The distribution of node number and centrality falls into the pyramid mode and the inverted ladder mode;the regional types of network connectivity are divided into four kinds,and every kind of regional type gradually shows its own special distribution feature.Secondly,market needs,central and local government and technological progress drive urban network spatial pattern evolution.
