Industrial divisions and the functional synergy of Chinese metropolitan areas
Metropolitan areas are pivotal in driving national economic growth,advancing harmonious regional development,and participating in competitive international collaboration.Consistent with international consensus,China's planning policies define metropolitan areas as a one-hour commuting circle.Simultaneously,these planning protocols particularly highlight the importance of industrial specialization and intercity collaboration,with the objective of developing modern urban agglomerations characterized by a well-defined spatial structure,complementary urban functions,and an integrated industrial division.This study uses the 2017 intercity input-output table analysis to examine patterns of industrial division and functional synergy in Chinese metropolitan areas.The findings are as follows:(1)From the perspective of industrial division and functional synergy,Chinese metropolitan areas can be categorized into four distinct spatial structures:the single-center dispersed structure,the core-periphery structure,the peripheral expansion structure,and the multi-center network structure representing an advanced phase in the spatial evolution of metropolitan areas.(2)The spatial network of industrial chains in Chinese metropolitan areas is predominantly governed by the flow of processing and manufacturing links.There is a substantial gap in the processing and manufacturing links between the Beijing and Tianjin metropolitan areas compared to similar types of metropolitan areas,and there is considerable potential for enhancing the productive service links in the Guangzhou,Chengdu,and Changsha-Zhuzhou-Xiangtan metropolitan areas.(3)The essence of transforming Chinese metropolitan areas into functionally complementary industrial cooperation areas is to further refine the spatial network of the industrial chains,strengthen functional synergy between cities,and encourage spatial integration in the metropolitan areas.(4)Single-center dispersed structure metropolitan areas,including Shijiazhuang,Chengdu,Wuhan,and Changsha-Zhuzhou-Xiangtan should initially transition toward a core-periphery structure.In contrast,peripheral expansion structure metropolitan areas such as Nanjing and Hangzhou metropolitan areas,and core-periphery structure urban agglomerations such as Tianjin,Shenzhen,Guangzhou and Beijing metropolitan areas should progress toward a multi-center network structure.
