解读首都都市圈的“三个圈”

Core Viewpoint - The "Modern Capital Urban Circle Spatial Collaborative Planning (2023-2035)" has been officially approved, marking a significant step in the coordinated development strategy of the Beijing-Tianjin-Hebei region, focusing on three spatial layers: commuting circle, functional circle, and industrial collaborative circle [1][3]. Group 1: Development Goals - The planning emphasizes the need for coordinated development goals among Beijing, Tianjin, and Hebei, with phased targets set for 2030, 2035, and 2050 [3]. - The construction of the capital urban circle is framed within the context of the Beijing-Tianjin-Hebei coordinated development strategy, aiming to enhance high-quality development [3]. Group 2: Functional Layout - The planning outlines a collaborative functional layout, leveraging the comparative advantages of each region to foster a mutually beneficial development pattern [3]. - Beijing is tasked with enhancing its "four centers" while alleviating non-capital functions to support the development of Tianjin and Hebei [3]. Group 3: Policy Measures - The planning proposes collaborative policy measures focusing on key areas and regions, aiming for integrated high-quality development [4]. - It highlights the importance of inter-provincial cooperation, particularly in areas like the Beijing-Tianjin-Hebei border regions, to achieve integrated development [4]. Group 4: Spatial Structure - The planning defines the spatial structure of the capital urban circle, which includes the commuting circle, functional circle, and industrial collaborative circle [6]. - The commuting circle is delineated based on a radius of approximately 50 kilometers, covering a population of high-frequency movement [6][7]. - The functional circle is set at a radius of about 100 kilometers, encompassing key areas in Beijing, Tianjin, and Hebei, with an area of approximately 42,000 square kilometers [7]. - The industrial collaborative circle extends to a radius of 150 kilometers, integrating the entire Beijing-Tianjin-Hebei urban cluster and connecting with surrounding urban groups [7].
