Beijing-Tianjin-Hebei region, which is the most densely populated area and plays an important role in China's regional development strategy, has aroused great concern from scholars. Influenced by the national macro policies, the research hotspots are in continuous evolution. In order to sort out the research hotspots in different periods and the network links between research hotspots, and have a deeper understanding of the research fields, research directions, and research status of scholars in various disciplines, bibliometrics and knowledge map visualized technology are used to examine the quantitative characteristics of literatures, the characteristics of journal and discipline distribution, the co-occurrence network structure map of research institutes, and the research hotspots in different periods and their evolution are summarized as well. In addition, we take the research papers of Beijing, Tianjin and Hebei in the collection of core journals, CSSCI, EI source journals and SCI source journals in CNKI (China National Knowledge Infrastructure) as the object of study. The research suggests that: (1) The number of publications of the Beijing-Tianjin-Hebei study is increasing, mainly in the four majors of economics, geography, sociology, and environmental studies, with geography ranking in the forefront of the volume of papers and journal impact factors; (2) Universities and research institutes located in the Beijing-Tianjin-Hebei region are the main forces of the research, and the co-occurrence network density is 0.0063, indicating that a cooperative network has initially been formed among universities and research institutes, but the degree of contact and cooperation is relatively low, and the research in various fields is relatively independent; (3) The study of Beijing, Tianjin and Hebei has gone through three stages, and the research hotspots at different stages have distinctive characteristics of the times, explaining that the Beijing-Tianjin-Hebei study is closely linked to the national macro policies. Since 2006, three major research directions have been formed: Beijing- Tianjin-Hebei integration and industrial restructuring, regional spatial structure and coordinated development strategies, as well as PM2.5 and atmospheric environment. Xiong'an new district, urban agglomeration, new urbanization, and carbon emissions have become new research hotspots.
