摘　　要：在京津冀协同发展快速推进的大背景下,进一步理清京津两个核心城市的辐射带动作用对于唱好“双城记”具有重要意义。基于区域双核结构理论,通过测算国内19个城市群的中心性和门户性指标并进行聚类分析,可以发现京津冀与其中7个城市群为双核结构;进而借助引力模型和场强模型,探讨京津冀区域内所有可能的双核结构组合,确定“北京-天津”是京津冀城市群内影响最大且最为稳定的双核结构,其中北京为中心城市,天津为门户城市。进一步分析不难发现,2019年之后京津双核结构的作用正在弱化,其在京津冀城市群内的功能有待进一步明确及发挥,尤其是天津如何进一步发挥其港口及门户城市的作用有待进一步探讨。In the context of the rapid development of the Beijing⁃Tianjin⁃Hebei region,understanding the dual⁃core structure’s dynamics is crucial for enhancing the performance of this regional framework.This study employs the theory of regional dual⁃core structure to analyze the centrality and gateway indexes of 19 city clusters in China,utilizing cluster analysis to identify that the Beijing⁃Tianjin⁃Hebei region,along with seven other clusters,exhibits a dual⁃core structure.By applying the gravity model and field strength model,the study explores various dual⁃core combinations within the Beijing⁃Tianjin⁃Hebei region,establishing Beijing⁃Tianjin as the most influential and stable dual⁃core configuration.In this setup,Beijing functions as the central city,and Tianjin as the gateway city.Further analysis reveals that the influence of the Beijing⁃Tianjin dual⁃core structure has been weakening since 2019.Therefore,it is imperative to refine and enhance the roles of both cities within the region,particularly focusing on optimizing Tianjin’s function as a port and gateway city.
