摘　　要：基于2004~2013年战略性新兴产业上市公司跨区布址数据,运用社会网络分析法对长江三角洲城市群空间结构演变规律进行了分析。研究发现:1长江三角洲城市网络的主要联系流由"Z"字形空间结构演变为"金字塔"形结构。2高行政级别城市在网络要素资源配置中占据主导地位,省会城市的中介能力呈现"倒U"型发展趋势。3沪杭宁甬苏合6城市构成了长三角城市网络的核心层,核心-边缘层联系成为占据主导地位的联系方式;城市网络凝聚子群具有明显的地理粘着性,沪宁和杭州凝聚子群分别是群内联系和群际联系的标杆。The spatial network structure of the Yangtze River Delta urban agglomeration is investigated using the social network analysis model based on the strategic emerging industries＇ listed companies data in 2004-2013. Major findings are as follows： Firstly, the traditional ＂Z＂-shaped backbone of the Yangtze River Delta＇ s city network turned into pyramid-shape which is anchored by Shanghai, Nanjing, Hangzhou, Hefei and Ningbo. Recent years have witnessed the accelerated growth in network linkage density of the Yangtze River Delta urban agglomeration. The city network structure is obviously polycentric and the centralization level has been constantly increasing. Various network linkage patterns coexist in the Yangtze River Delta urban agglomer- ation. Secondly, core node cities have played increasingly important roles in resources allocation. Provincial cap- itals and sub-provincial cities show overwhelming advantage of resources agglomeration and radiation in the ur- ban network, but a U-shaped pattern can be found in their betweenness centrality. Thirdly, Shanghai, Nanjing, Hangzhou, Ningbo, Suzhou, Hefei constitute the core layer of the Yangtze River Delta＇ s city network and the linkage between core cities and peripheral ones has become the dominating pattem. The member structure of cohesive subgroups presents obviously regional trend. Shanghai-Nanjing cohesive subgroup and Hangzhou cohesive subgroup are the leading one in the field of intra-subgroup linkage and inter-subgroup linkage respectively.
