摘　　要：以长三角城市群41个主要城市为研究单元,研究了绿色发展视角下的城市创新网络问题。通过引力模型得出各城市创新联系强度,进而运用社会网络分析方法研究城市群创新网络结构特征。结果表明:绿色发展视角下长三角城市群创新网络密度较低,阻碍了创新要素的传递,网络中心势不高,集中程度低,网络凝聚力不强;根据网络节点中心度数发现,以发达城市为核心的半轮轴型集聚格局基本形成;网络中结构洞数目不断增加,网络结构不断优化;网络核心-边缘结构呈现,核心区域空间集聚效应明显;由块模型得出8大子群,子群特征呈现多样化。The paper takes 41 major cities in Urban Agglomeration of Yangtze River Delta as examples and researches me innovation network under restraint of green development. And then it calculates the linkage of regional green innovation by the gravity model, and researches the network structure feature on the basis of the social network analysis. Five results are as follows. Firstly, the result shows that the low density of network hinders the resource transfer. Secondly, according to the centrality degree, several developed urban areas formulate a core group, and are surrounded by the other low-- degree cities. Thirdly, the number of the structural holes in the network grows. Fourthly, as for spatial dimension, the core areas exhibit a clear trend of the spatial distribution pattern. Lastly, there exist 8 cliques according to the CONCOR method of block models. Some cliques are reflexive. The first and fifth ones are transmitters, and the forth and the sixth are receivers. Besides, the second clique and the eighth clique are isolates.
