Research on Twenty Years' Coordinated Development of Beijing-Tianjin-HebeiProgress and Prospects

The Beijing-Tianjin-Hebei coordinated development is an important part of the national regional coordinated development strategy, and its research has been a hot topic in academic circles. This paper uses CiteSpace software, a literature visualization tool, and takes CNKI's core journals from 2004 to 2024 as the main data source to visually analyze the annual number of published papers, research institutions, published journals, disciplines involved, evolution context and research content of the literatures on the Beijing-Tianjin-Hebei collaborative development. Through the cluster analysis of literature keywords, it is found that the research content of Beijing-Tianjin-Hebei collaborative development focuses on four categories: collaborative development, regional economy, development path and ecological environment. In the future, efforts should be made to consolidate the research strength of Beijing-Tianjin-Hebei and establish a research network for the coordinated development of Beijing-Tianjin-Hebei. It is necessary to enrich the research content of Beijing-Tianjin-Hebei, expand the research perspective of Beijing-Tianjin-Hebei coordinated development, enhance the research level of Beijing-Tianjin-Hebei, and improve the theoretical system of Beijing-Tianjin-Hebei coordinated development so as to deepen the research of Beijing-Tianjin-Hebei coordinated development.
