长三角城市群生产性企业出海驱动下的全球城市网络重构OACHSSCD

Since the Belt and Road Initiative was proposed in 2013,Chinese enter-prises have accelerated their overseas expansion.Cross-border linkages,driven by productive enterprises as key actors and facilitated by the globalization of industrial and supply chains,are reshaping traditional global networks.Based on an analysis of subsidiaries established by Yangtze River Delta enterprises in Southeast Asia from 2000 to 2025,this paper maps the headquarter-subsidiary network and examines its spatial process and global implications.A distinctive network configuration has emerged,characterized by dominant connectivity between cities along the Shanghai-Nanjing-Hangzhou-Ningbo corridor and Singapore.Peripheral municipal districts and counties are embedded through extensive but low-intensity connections.The network has evolved from a single-axis structure toward a configuration combining axis stabil-ity,node spillover,and hinterland embedding.This transformation is increasingly driven by policy incentives,industrial-chain extension,and cluster embedding rather than cost advantages alone.This process contributes to a westward shift of the Pa-cific Rim city network and the vertical densification of its western segment,reflect-ing the transformation of Chinese cities from market gateways into resource coordina-tors in the globalization process.
