To deeply explore the knowledge production status and development logic in the field of risk communication for public health emergencies in China，this study systematically sorts out 234 core literatures from CNKI using bibliometrics and content analysis. First，the knowledge production trend is summarized through quantitative statistics; second，the Citespace software is used to construct a visual knowledge map of the main subjects and carriers of knowledge production and core issues，analyzing the current situation of knowledge production; finally，the content logic and process logic of knowledge production are sorted out through content analysis of the literature. The results show that the current knowledge production of risk communication for public health emergencies in China is driven by both "push" and "pull" factors. There is an obvious trend of interdisciplinary crossover，the content system of knowledge production is taking shape; and the methods of knowledge production are characterized by diversity.
