[Result/conclusion] The results of this study are as follows: IR articles publishing had experienced rapid development period, the relative stationary period, and downturn period, which means that the current research of domestic IR has reached a new stage, and have new research hotspots; the high-frequency authors (groups) are mainly composed of the authors of the Chinese Academy of Sciences and universities, the former's research is more advanced and deeper than the latter; "Library and Information Service", "Journal of Modern Information", "Researches in Library Science", etc. are the most published journals with IR research papers, and are more influential in the field of IR research in China; research hotspots of domestic IR include system construction, resource construction, academic communication, knowledge management and services, copyright protection, etc.; future research hotspots include research data, scientific research services, auxiliary research decisions, and data value-added services.
