官方解答首都都市圈空间范围和“三个圈层”划定相关问题

Core Viewpoint - The first urban agglomeration plan approved by the Central Committee of the Communist Party of China and the State Council, titled "Modern Capital Urban Agglomeration Spatial Coordination Plan (2023-2035)," has been released, highlighting the unique advantages and roles of the capital urban agglomeration in various aspects such as politics, ecology, economy, and security [1][2]. Group 1: Urban Agglomeration Overview - The capital urban agglomeration is characterized by its role as the only urban agglomeration in China with two municipalities, serving as a crucial support for the coordinated development of Beijing-Tianjin-Hebei [1]. - The spatial scope of the capital urban agglomeration includes a multi-layered, nested "concentric circle" model, which is innovative compared to traditional "one-hour commuting" ranges [1]. Group 2: Commuting Circle - The commuting circle considers the current cross-border commuting rate and the comprehensive transportation reach within one hour, covering a total area of approximately 27,000 square kilometers, which includes all of Beijing and 12 surrounding districts and counties [1]. Group 3: Functional Circle - The functional circle represents the core area for the development of the capital urban agglomeration, encompassing Beijing, Tianjin, Xiong'an New Area in Hebei, and parts of Langfang, Baoding, and Zhangjiakou, with a total area of about 42,000 square kilometers [2]. Group 4: Industrial Coordination Circle - The industrial coordination circle serves as an open area for the development of the capital urban agglomeration, extending its influence across the entire Beijing-Tianjin-Hebei urban cluster and coordinating with surrounding urban clusters such as Liaoning Central South, Shandong Peninsula, and Central Plains [2]. - This circle aims to efficiently connect with major domestic urban clusters like the Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu-Chongqing, and the middle reaches of the Yangtze River, establishing a multi-level collaborative and open pattern that reaches both nationally and globally [2].
