Examining the intellectual foundations of PBL research in China contributes to a deeper understanding of its theoretical and practical dimensions. Using Cite Space to analyze 156 PBL-related articles from the CSSCI database reveals that the knowledge base is primarily constructed from two domains:1.Theoretical foundation—Cited authors and literature focus on PBL's conceptual framework and value, encompassing interdisciplinary PBL, core competency development, and educational objectives； 2.Empirical studies—Key references emphasize case studies across K-12 education, general high schools, and tertiary education. In the future, project-based learning should delve into exploring the connotation and value of project-based learning from a dual-subject comprehensive perspective, conduct case studies on project-based learning in vocational education, and promote interdisciplinary integration of core competencies through project-based learning.
