摘　　要：长三角城市群的信息辐射空间呈现复杂网络特性,网络密度和关联度较高,等级性较低,空间重构初步显现。城市群内中心性较高的城市普遍多于中心性较低的城市,网络联动效应明显,信息结构洞总体呈现以上海、南京、杭州、苏州、无锡和宁波为多中心的开放网络化结构。宿迁、泰州和衢州等城市的限制度相对较高,但与核心城市的差距不断缩小。整个信息关联网络可分为8个子群,子群分布已弱化地域限制而出现跳跃性带动群体。依托8个子群为基础空间单元,长三角城市群空间组织重构为辐射簇群(子群(1)、(2))、中介簇群(子群(3))、跳跃性簇群(子群(4)、(5))和初级簇群(子群(6)、(7)、(8))等四个"簇群"状空间组织。The information radiation space of Yangtze River urban agglomeration shows complex networks, with a high degree of network density and connectedness, and a low degree of hierarchy. Besides, space reconstruction has began to ap- pear. In the urban agglomeration, the number of high-centrality cities is greater than the number of low-centrality cities, and there is an obvious effect of network linkage. In addition, the information structure hole overall presents an open network struc- ture with Shanghai, Nanjing, Hangzhon, Suzhou, Wuxi and Ningbo as the centers. The degree of restriction in Suqian, Taizhou and Quzhou is relatively high, but the gap with the core cities is shrinking. The entire information-associated network can be divided into 8 subgroups, based on which the Yangtze River urban agglomeration can be restructured into 4 main ＂clus- ter-like, spatial organization, including Radiation Clusters （ subgroups 1, 2 ） , Intermediate Cluster （ subgroup 3 ） , Jumping Clusters （ subgroups 4, four 5） and Primary Clusters （ subgroups 6, 7, 8）.
