Synergistic Development of Cross-District Hub Clusters:Emerging Trends in the Shenzhen Metropoli-tan Area
As metropolitan areas rapidly advance and achieve a high level of urban spatial maturity,peripheral dis-tricts are transforming into key platforms for regional development.Within the Shenzhen metropolitan area,the cross-border areas of Shenzhen and other cities have developed into urban corridors characterized by industrial spillover and population migration.These corridors have further fragmented into various functional clusters,each with an increasing concentration of hubs.This study explores such corridors with hub clusters,offering a novel as-sessment of their development characteristics and challenges across five dimensions:hub accessibility,central alignment,enterprise agglomeration,functional coordination,and hub synergy.The findings underscore a press-ing need for integrated development of these hub areas,harnessing their advantageous resource endowments and diverse conditions.However,significant obstacles remain due to administrative and natural boundaries.Issues such as cities without stations and stations detached from cities continue to impede progress.To address these challenges,there is a need to optimize the integration of stations with cities and enhance the synergy between ur-ban areas and hub clusters.Specifically,upgrading hub functions and aligning industrial development around sta-tions with local needs is crucial.Additionally,the placement of new towns and functional nodes in areas across districts should be coordinated with hub arrangements to create cohesive development units,thereby facilitating the sustainable evolution of the metropolitan area's functional network.
