Abstract: In order to systematically study the hotspots and frontier dynamics of fire investigation and research in China, CiteSpace and VOSviewer software were used to visually analyze 565 research literatures included in CNKI journal database by using bibliometric methods such as cooperative analysis, citation analysis and co-word analysis. The results show that from 2003 to 2020, the number of fire investigation literature published is on the rise, and it begins to show a downward trend in 2021. From 2003 to 2023, the top 5.1% institutions accounted for 32.21% of the total number of publications, and the top 3.9% authors accounted for 18.9% of the total number of publications. The relationship between the authors of fire investigation and research is not strong, and only a small number of cooperative groups have been formed. "Fire investigation" "Fire" and "on-site inspection" have high centrality and are the core nodes of fire investigation. The research perspective of scholars is relatively concentrated in the early stage, but there has been a trend of changing to a new perspective. The results of this study are expected to provide reference for the theoretical research and practical development of fire investigation in China.
