摘要
全球化进程正经历由“扁平开放”向“区域社群化”的结构性转变,传统基于新自由主义的资本逻辑的全球城市理论面临阐释危机。本文以包容性全球化的新视角,应对新地缘边界,基于全球创新网络、生产与服务网络、联通设施网络三大维度,构建网络协同评价框架,运用介数中心性算法识别“中介城市”,运用度中心性算法识别“双循环枢纽城市”,对全球城市格局演变进行分析。研究发现:全球城市网络“沟壑纵横”呈现结构性割裂与再区域化的新边界特征,创新、产业、设施联通均出现显著的区域分化;伦敦、北京、东京、纽约、旧金山等仍居全球创新体系塔尖,但由中美引领的技术竞争格局日趋明显;中国香港地区、新加坡、迪拜等“中介城市”凭借独特网络位置成为跨社群连接的关键节点;北京、上海、中国香港地区、深圳、广州等构成中国“双循环枢纽城市”第一梯队。研究表明,未来城市竞争力取决于其在社群间的穿透能力与网络韧性,中国需依托“四个扇面”开放格局与多中心创新网络,继续构建包容韧性的高质量开放新体系。
The process of globalization is undergoing a structural transformation from a model of“flattened openness”toward one characterized by regional clustering and community-based reorganization.As a result,traditional global city theories grounded in neoliberal capital logic are increasingly confronted with explanatory limitations.Adopting the perspective of inclusive globalization in response to emerging geopolitical boundaries,this study constructs a network synergy evaluation framework based on three dimensions-global innovation networks,production and service networks,and infrastructure connectivity networks-to analyze the evolving configuration of global city systems.Using betweenness centrality to identify intermediary cities and degree centrality to identify hub cities within China’s dual-circulation development framework,the study examines shifts in the global urban hierarchy and network structure.The findings reveal that the global city network has developed pronounced structural fissures,exhibiting new boundary effects marked by fragmentation and re-regionalization,with innovation,industrial linkages,and infrastructural connectivity showing significant regional differentiation.While cities such as London,Beijing,Tokyo,New York,and San Francisco remain at the apex of the global innovation system,a technology-driven competitive landscape led by China and the United States is becoming increasingly evident.Intermediary cities such as Hong Kong region of China,Singapore,and Dubai,by virtue of their distinctive network positions,have emerged as critical nodes facilitating cross-community connectivity.Meanwhile,Beijing,Shanghai,Hong Kong region of China,Shenzhen,and Guangzhou constitute the first tier of China’s dual-circulation hub cities.The study demonstrates that future urban competitiveness will hinge on a city’s capacity for cross-community penetration and network resilience.To this end,China should continue to advance the construction of an inclusive and resilient high-quality open system by leveraging its“four-quadrant”opening framework and a polycentric innovation network.
