In order to fully understand the status quo of research on prefabricated buildings, and the hotspots and frontier trends of research on prefabricated buildings are grasped,taking the core journal documents related to the research of prefabricated buildings collected by CNKI from 2010 to 2020 as the data source, and using CiteSpace visualization network tools, the knowledge graph analysis is carried out from the aspects of time distribution, space cooperation, author cooperation, hotspots, and cutting-edge topics.The results show that: In terms of literature statistics, the annual volume of prefabricated research has shown an increasing trend. Building structure, building economics, and concrete are the core journals that publish more prefabricated building literature.In terms of research institutions and authors, Shenyang Jianzhu University,Xi'an University of Architecture and Technology, Wuhan University of Technology and other institutions, as well as highly productive scholars from these institutions, form the core research force of prefabricated buildings.In terms of research hotspots, BIM technology,deepening design, seismic performance, building industrialization and EPC mode are the core of existing research.The evolution and development process of prefabricated building research is mainly divided into two stages: slow development and rapid development. The frontiers of research mainly include BIM technology, industrialization, prefabricated components, modularization and comprehensive evaluation. The research results are expected to provide reference for the development of prefabricated buildings, it also provides reference for the hotspots and frontier analysis in the subject field.
