Research Progress and Hotspot Analysis of Prefabricated Buildings–Scientific Metrological Analysis Based on Citespace

Abstract

This study utilized the world’s largest Chinese database, the Chinese National Knowledge Infrastructure (CNKI), and selected 4984 studies on PBs from Web of Science and Scopus (W&S) and CNKI. We systematically analyzed the research status, developmental trajectory, and potential trends of PBs. The results show that: (1) the number of PB studies in CNKI has exhibited steady year-on-year growth, entering a stable phase of development; (2) W&S and CNKI each have their own independent and complementary focus; (3) These two datasets are more similar in terms of the nature of research institutions, but inter-institutional cooperation in W&S is closer than that in CNKI. The clustering effect among research institutions in China is not good; (4) The top five topics of W&S research are performance, design, construction, seismic performance, and influencing factors. Emergent issues such as safety, environmental protection, energy conservation, and sustainable development are critical.
