城记 | 上海大都市圈，究竟“大”在哪里——访华东师范大学终身教授曾刚

Core Viewpoint - The "Action Plan" for the integrated development of the Yangtze River Delta urban agglomeration aims to enhance the level of integration by 2035, focusing on the Shanghai metropolitan area as a core region for resource integration and world-class industrial cluster development [1][2]. Group 1: Shanghai Metropolitan Area Development - The Shanghai metropolitan area covers 14 cities and is positioned as a global competitive entity, moving from regional development to global engagement [2][3]. - The area contributes 14.5% of China's economic output while only occupying 1.2% of the land area and housing 7.7% of the national population [3]. Group 2: Urban Integration and Collaboration - The concept of "same city" integration in the Shanghai metropolitan area is defined by three levels: daily commuting (1-hour), business travel (1.5-hour), and industrial collaboration (up to 2.5-hour) [4][5]. - The integration aims to facilitate cross-regional resource flow and collaboration, with a focus on industrial synergy rather than competition among member cities [5][6]. Group 3: Cross-Provincial Collaboration - The Shanghai metropolitan area serves as a model for cross-provincial industrial collaboration, with a notable increase in joint applications for advanced manufacturing clusters [7]. - The Yangtze River Delta's efforts in creating a world-class aircraft manufacturing cluster exemplify successful cross-provincial collaboration, involving multiple cities and significant industrial output [7][8]. Group 4: Strategic Focus for Future Development - The metropolitan area is urged to prioritize the creation of world-class industrial clusters during the 14th Five-Year Plan, focusing on cultivating globally competitive companies and establishing influential international organizations [8].
