[Method/process] This paper used bibliometricanalysis to study from the perspectives of time trend, organization distribution, periodical distribution, etc.,and summarized the application status in detail. Secondly, the LDA topic model was used to identify themain international and domestic research directions and conducted a comparative analysis. Finally, thispaper summarized the problems in the application and proposed future prospects. [Result/conclusion] Theapplication of topic models in the analysis of public policy texts is on the rise overall and has broad prospects.The starting time of domestic and foreign research is equivalent, but domestic research needs to be improvedin terms of research scope, research depth, cooperation methods, and research methods. In addition, in thefuture development, there are problems with the applicability of the topic models own methods and thegranularity of research content. It is necessary to further combine the characteristics of public policy texts toimprove the topic model and refine research efforts.
