[目的/意义]基于近年来知识付费的研究现状，对比国内外知识付费的科研产出情况，探索知识付费的研究热点和发展趋势，为知识付费行业的发展提供新的参考导向。[方法/过程]利用CiteSpace软件对国内和国外相关研究文献进行知识图谱可视化分析，通过对文献作者、期刊、关键词和摘要的内容研究，分析其研究成果，并进行国内外对比。[结果/结论]国内外学界对知识付费研究的关注度日益加强，国外注重用户持续使用意愿、用户知识共享动机和用户付费动机等方面的研究，而知识付费平台的发展策略研究、知识共享到知识付费的转变、直播短视频行业下的知识付费形式和知识生产的精细化发展等成为国内知识付费的研究热点和前沿，国内与国外的研究侧重点不同，因此，需要借鉴与融合国外研究，推进国内知识付费研究的创新与发展。

[Purpose/Significance] Based on the research status of payment for knowledge in recent years, comparing the research outputs of payment for knowledge at home and abroad, to explore the research hot spots and development trends of payment for knowledge, and to provide a new reference for the development of the knowledge payment industry. [Method/Process] This study used CiteSpace software to visualize the knowledge map of domestic and foreign related research documents, analyzed the research results and conducted domestic and international comparisons, through the content research of the authors, journals, keywords and abstracts of the document. [Result/Conclusion] The research conclusions show that the domestic and foreign academic circles pay more attention to the research of knowledge payment. Foreign countries pay attention to the research of users' continuous use intention, user knowledge sharing motivation and user payment motivation, and the development strategy research of knowledge payment platforms, the transformation of knowledge sharing to knowledge payment, and the refined development of the form of knowledge payment in the live short video industry and knowledge production have become the research hotspots and frontiers of knowledge payment in China. The focus of domestic and foreign research is different. Therefore, it is necessary to learn from and integrate foreign research, to promote the innovation and development of domestic knowledge payment research.
