The work aims to visually analyze the research of persuasive design in the past two decades through the bibliometric method, to explore the current research status and future development trends of persuasive design, and play a reference and enlightening role for the research of persuasive design in China. In this research, the Web of Science database was used as the data source, R bibliometrix and VOSviewer were used to generate scientific knowledge graphs. R bibliometrix package was used for quantitative analysis of the annual scientific publication, country, institution, author and journal, and VOSviewer was used to construct a network analysis of literature co-citation and keyword co-occurrence. The results show that the persuasive design publications are increasing year by year, showing a phenomenon of multidisciplinary integration. The United States is the most contributory and influential research country, and the University of Oulu is the most contributory institution. Scholar Harri Oinas-Kukkonen is the most influential author in this field. The cited documents form a total of four clusters, namely behavior theory, persuasion technology theory, interdisciplinary research, and human-computer interaction persuasion. Keyword clustering presents five major research hotspots, namely persuasion results, persuasion fields, persuasion media, persuasion techniques, and persuasion strategies, forming a complete persuasion relationship chain. Health intervention is an important point and research direction of persuasive design. In the future, persuasion design will be transformed to "digital", and the content and technology of persuasion will be expanded with the current context and user needs.
