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 is entering a new phase of development planning, 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 initiating new planning cycles [3][4]. - 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 integrated transportation, industrial collaboration, public service co-construction, and cross-provincial governance [4][6]. - The metropolitan area is recognized for its advanced urban integration, with efficient transportation links allowing for 30-minute commutes to core cities like Zhenjiang and Yangzhou, and 1-hour commutes to cities like Chuzhou and Ma'anshan [6]. - However, there are identified shortcomings in transportation efficiency, industrial homogeneity, and public service availability that need to be addressed in the new planning [6][8]. Group 3: Key Focus Areas for New Planning - The new planning emphasizes transportation integration through "railway metropolitan areas," aiming for a one-hour commute and improved connectivity [8]. - In terms of industry, the focus is on strengthening the "headquarters + base" model to promote cross-regional industrial chain integration [8][9]. - Public service improvements are also a priority, including the distribution of educational and healthcare resources, as well as social security integration [8][9]. Group 4: Policy and Market Dynamics - The central government has shifted its urban development focus from "incremental expansion" to "quality enhancement," emphasizing coordinated development across various sectors [9]. - The effectiveness of the new metropolitan area planning will depend on the establishment of an "effective market" and the practical implementation of policies that support sustainable industry [9][12]. - The recent approval of the Hefei metropolitan area as a pilot for market-oriented reform highlights the potential for broader regional coordination and resource optimization [11][12]. Group 5: Lessons from Existing Metropolitan Areas - Existing metropolitan areas provide valuable lessons for new and future metropolitan areas, particularly in addressing industrial imbalances and administrative barriers [13]. - The relationship between central and surrounding cities is crucial, with successful examples demonstrating the importance of resource sharing and collaborative development [13][14]. - The dual circulation of public services, as seen in Wuhan, showcases effective strategies for talent distribution and service enhancement across metropolitan areas [14].
