Hot Spots, Trends and Frontiers of Research on the Coordinated Development of Beijing, Tianjin and Hebei

This paper takes 2126 journal documents on the coordinated development of Beijing, Tianjin and Hebei on CNKI from 2009 to 2022 as research samples, and uses NoteExpress and CiteSpaceV software to analyze the time distribution, research strength, research hotspots, trends and cutting-edge of the research on the coordinated development of Beijing, Tianjin and Hebei. The results show that the research and policy of the coordinated development of Beijing, Tianjin and Hebei maintain a high degree of synergy, and the research force has a strong regional nature. Most of them are scholars, universities and institutions in the Beijing-Tianjin-Hebei region. Many large cooperation networks have been formed between the authors, but there are few cooperation links between institutions. Scholars mainly focus on the seven hot spots of Beijing-Tianjin-Hebei transportation integration, regional economic coordinated development, soft environmental resources coordinated development, ecological environment coordinated protection and governance, Beijing-Tianjin-Hebei Urban Agglomeration construction, “one core”, “two wings” and Winter Olympic heritage. The theme evolution is mainly divided into three stages: starting, rapid development and precipitation. In recent years, the research frontiers are space-time differentiation, driving factors, influencing factors, regional synergy and water resources research.
