盘点长三角|都市圈同城化的突破与进化

Core Viewpoint - The implementation of the "Action Plan" in 2025 will accelerate the integration of the Yangtze River Delta urban agglomeration, enhancing infrastructure connectivity, industrial collaboration, and public service sharing, thereby unlocking development dividends [1][2]. Infrastructure Connectivity - The Yangtze River Delta will focus on creating a unified infrastructure network, with significant progress in road and rail connectivity, including the completion of three previously disconnected roads and a 15% increase in road network density along the Ning-Hang Ecological Economic Belt [2]. - By October 2025, the total railway operating mileage in the Yangtze River Delta will exceed 15,000 kilometers, with high-speed rail mileage surpassing 7,700 kilometers, establishing a "one-hour commuting circle" among core cities [2]. Industrial Collaboration - The region will see a "cohesion effect" in industrial innovation, with over 300 billion yuan invested in cross-regional industrial cooperation projects [3]. - The Yangtze River Delta has formed 26 advanced manufacturing clusters, accounting for one-third of the national total, with leading industries such as integrated circuits, biomedicine, and artificial intelligence dominating the market [3]. Public Service Sharing - The region will enhance public service equality, with over 236,000 cross-province medical insurance settlements and 54 billion yuan in medical expenses settled by 2025 [4]. - The average PM2.5 concentration in the region will decrease by 8% year-on-year, reflecting significant improvements in ecological cooperation [4]. Economic Growth - The Yangtze River Delta contributes 24.6% of the national GDP with an average annual growth rate of 5.58% from 2018 to 2024, outperforming the national average [4][6]. - The number of "trillion-yuan cities" in the region has increased to nine, with Shanghai, Suzhou, and Hangzhou each surpassing 1 trillion yuan in GDP in the first half of the year [4]. Challenges and Opportunities - Despite significant economic advantages, the Yangtze River Delta faces challenges in matching the quality and collaborative efficiency of international urban agglomerations like New York and Tokyo [7][8]. - The region's urban agglomerations exhibit a "bite" relationship, but there is still a need for tighter connections and interactions among them to achieve comprehensive collaborative development [7]. Future Directions - In 2026, the focus will be on enhancing infrastructure efficiency, with planned investments exceeding 500 billion yuan in transportation projects [9]. - The industrial collaboration will shift from "project cooperation" to "ecological co-construction," aiming to establish a new pattern of innovation community [10]. - Legislative measures will be accelerated to address the lack of legal empowerment, with 3-5 local collaborative regulations planned to ensure unified and stable development [11].
