摘　　要：为探究中心城市经济辐射对城市群发展的影响,基于经济辐射相关理论,选用京津冀城市群2014—2021年相关数据,利用断裂点模型和辐射场强模型,从经济辐射格局“点—线—面”的角度对京津冀中心城市经济辐射效应进行分析。研究发现:京津冀城市群“强极核”模式凸显,城市间经济发展不均衡,中心城市经济实力突出但彼此之间实力悬殊;中心城市的辐射强度均有所上升但变化幅度差距较大,辐射方向均呈放射状向外围扩散,形成显著的“中心—外围”结构形态;中心城市经济辐射腹地呈现出以北京、天津、石家庄与唐山四点构成的菱形结构为支撑、其他中小城市为重要节点的辐射空间格局,不同中心城市辐射腹地彼此融合、相互嵌套,形成互补支撑、协同联动的多尺度空间网络格局。Based on the economic radiation theories,this paper adopts data from Beijing-Tianjin-Hebei metropolis 2014-2021,and explores the central city economic radiation effects on the metropolis development.Specifically,it applies the break point model and radiation field intensity model,and then analyzes the central city economic radiation effects of Beijing-Tianjin-Hebei from the perspective of the“point-line-plane”economic radiation pattern.Research findings are as follows:the“strong polar core”model of Beijing-Tianjin-Hebei metropolis is prominent,while the economic development of each respective city is imbalanced.The economic strength of central cities is prominent with a huge strength gap between cities.The radiation intensity of all central cities has increased,with a markedly different increase amplitude.The radiation direction is radially diffused from the center to the periphery,forming a distinct“center-periphery”structure.The economic radiation hinterland of central cities presents a spatial radiation pattern supported by a diamond-shaped structure composed of Beijing,Tianjin,Shijiazhuang and Tangshan,with other small and medium-sized cities as important nodes.The radiation hinterland from different cities integrates and nests with each other,forming a multi-scale spatial network with complementary support and synergistic interaction.
