详解“首都都市圈”的三个“协同”与“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: Three "Collaborations" - The planning emphasizes the need for collaborative development goals among Beijing, Tianjin, and Hebei, with phased construction targets set for 2030, 2035, and 2050 [3][4]. - Functional layout collaboration is crucial, leveraging the comparative advantages of each region to foster a synergistic development model [4][5]. - Policy measures must also be coordinated, focusing on key areas and tasks to deepen collaboration across the three provinces [5][6]. Group 2: Structure of the Three Circles - The planning outlines three circles: the commuting circle, functional circle, and industrial collaborative circle, which are defined by different spatial dimensions [6][7]. - The commuting circle is approximately 50 kilometers in radius, covering a population of high-frequency movement areas, including all of Beijing and 12 surrounding districts, totaling about 27,000 square kilometers [7]. - The functional circle, with a radius of about 100 kilometers, includes Beijing, Tianjin, and parts of Hebei, covering around 42,000 square kilometers, and serves as the core area for urban development [7]. - The industrial collaborative circle extends to a radius of 150 kilometers, encompassing the entire Beijing-Tianjin-Hebei urban cluster and connecting with surrounding city groups, aiming for a multi-layered collaborative open structure [7][8].
