南京都市圈GDP突破5.4万亿，中国城市竞争释放新信号

Core Viewpoint - The Nanjing metropolitan area has initiated a new round of development planning, marking the beginning of a new phase in modern metropolitan area construction, with a projected GDP exceeding 5.4 trillion yuan in 2024, positioning it among the top metropolitan areas in China [1][3]. Group 1: Development Planning - The modern metropolitan area planning began in 2019, with the National Development and Reform Commission (NDRC) issuing guidelines for the cultivation and development of modern metropolitan areas [3]. - As of now, there are 17 national-level metropolitan areas approved by the NDRC, including Nanjing, Fuzhou, Chengdu, and others, with many of these areas, including Nanjing, set to start new planning cycles [3][7]. - The focus of the new planning includes spatial layout, cooperation mechanisms, and urban integration [3]. Group 2: Urban Integration and Collaboration - Nanjing is transitioning from "geographical proximity" to "functional enhancement," emphasizing rail integration, one-hour commuting, industrial collaboration, and cross-province governance [5][7]. - The Nanjing metropolitan area is recognized for its advanced urban integration and industrial collaboration, with a well-established rail network allowing for 30-minute access to core cities [7]. - However, there are identified shortcomings in transportation efficiency, industrial homogeneity, and public service availability that need to be addressed in the new planning [7][8]. Group 3: Future Directions and Policy Framework - The main development direction for metropolitan areas is urban integration, with transportation integration being a priority [8]. - The new planning emphasizes the need for a "rail-based metropolitan area" to enhance commuting efficiency and integrate various transportation networks [8][10]. - The focus will also be on strengthening the "headquarters + base" model for industrial development and improving public service accessibility [8][10]. Group 4: Element Marketization and Reform - The State Council has approved ten regions, including the Hefei metropolitan area, to conduct comprehensive reforms for market-oriented allocation of elements, aiming to enhance the efficiency of technology transfer and resource allocation [12][13]. - Hefei's reform pilot aims to leverage its scientific capabilities to boost regional industrial strength and improve the efficiency of technology commercialization [12][13]. - Successful implementation of Hefei's model could provide a replicable framework for other metropolitan areas in China, promoting regional coordination and market-oriented reforms [13][14].
