摘　　要：文章通过社会网络分析方法,深入探讨长三角城市群中上海五大新城(嘉定、青浦、松江、奉贤、南汇)在经济联系方面的演进特征和区域网络中的地位变化。文章选取2006、2014和2022年三个时间节点截面,基于企业“总部-分支机构”联系网络,从网络综合排名、节点媒介作用、节点韧性功能和节点对外联系特征四个方面对新城在区域网络中的空间联系特征进行测度。结果发现,随着长三角一体化进程的推进,五大新城在吸引企业总部落地、网络媒介作用和对市域外联系等方面的表现显著提升,在网络中发挥了重要的协调和桥接作用。然而,新城在分支机构吸引能力、节点自身韧性水平改善等方面仍然面临挑战,距离其成为独立的综合性节点城市仍有不小的提升空间。This study employs social network analysis for in-depth exploration of the evolutionary characteristics of economic connections and changes in regional network status of five new cities in Shanghai(Jiading,Qingpu,Songjiang,Fengxian,and Nanhui)within the Yangtze River Delta urban agglomeration.The research selects three time points,2006,2014,and 2022,based on the“headquarters-branch”network of enterprises,to measure the spatial connection characteristics of the new cities in the regional network from four perspectives:overall network ranking,node intermediary role,node resilience function,and node external connectivity characteristics.The study finds that with the advancement of the integration process in the Yangtze River Delta,the five new cities have significantly improved their performance in attracting the landing of corporate headquarters,network intermediary role,and external connections to the city,playing an important role in coordination and bridging within the network.However,the new cities still face challenges in attracting branch institutions and improving the resilience level of nodes themselves,and there is still a considerable room for improvement before they become independent comprehensive node cities.
