In professional degree postgraduate education, professional practice, as a unique and important cultivation link, is not only a key process distinguishing it from academic postgraduate cultivation, but also an important institutional design for testing the quality of professional degree postgraduate education and the effectiveness of reform. With the help of CiteSpace data analysis and visualization tool, 1110 papers in China National Knowledge Infrastructure(CNKI) were used as the research samples, and bibliometric method was adopted to systematically describe and analyze the number of publications, core authors, partnership network and frontiers and hot topics in the field of professional practice of professional degree graduate education in the past two decades (2000-2024). The analysis results show that there is a general upward trend in the number of publications in the research area of professional practice of professional degree students. There is little cooperation between the core authors and the research institutions, and the research hot topics are greatly influenced by the national policies and social demands, the core themes are mainly centered on practice bases, cultivation modes, dual tutorship, teaching reform and practice innovation, etc. The research hot topics are gradually shifted to the integration between industry and education and classified training modes for graduate students. In the future, the reform of professional practice of integration between industry and education in the new era should be further explored to improve the quality of talent cultivation of professional degree graduate students.
