This bibliometric study aims to map the conceptual structure of intellectual capital (IC) research between 1975 and 2020 using co-word analysis and social network analysis drawing upon the Web of Science database. The results show that 12,310 documents have been published from 1975 to 2020. From a total of 6,516 keywords used in documents, the five most frequent keywords have been identified as: “performance”, “innovation”, “knowledge”, “impact”, and “management”. The United States is the top-producing country with 3,303 documents. In addition, the findings indicate that the Journal of Intellectual Capital is the most prolific journal with 208 articles, and the Academy of Management Journal is the most frequently cited journal with 11,914 citations. The National Bureau of Economic Research (NBER) is the world's most prolific research institute with 84 documents. The most frequently used keywords in different geographical regions show that except for South America, where the most frequently used keyword is "innovation", "performance" is the most common keyword in Asia, Europe, North America, Oceania, and Africa. This study provides a comprehensive picture of the current state of IC research, thereby paving the way for future studies by shedding light on the gaps in the literature and presenting suggestions for future research.

这项文献计量研究旨在利用 Web of Science 数据库的共词分析和社交网络分析，绘制 1975 年至 2020 年间智力资本 (IC) 研究的概念结构。结果表明，从 1975 年到 2020 年，共发表了 12310 篇文档。在文档中使用的总共 6516 个关键词中，五个最常用的关键词被确定为：“绩效”、“创新”、“知识”、“影响”、和“管理”。美国是最大的生产国，拥有 3,303 份文件。此外，调查结果表明，《智力资本杂志》是最多产的期刊，有 208 篇文章，而管理学院期刊是被引用次数最多的期刊，被引用次数为 11,914。美国国家经济研究局 (NBER) 是世界上最多产的研究机构，拥有 84 份文件。不同地理区域使用频率最高的关键词显示，除南美洲使用频率最高的关键词是“创新”外，“绩效”是亚洲、欧洲、北美、大洋洲和非洲最常用的关键词。本研究全面介绍了 IC 研究的现状，从而通过阐明文献中的空白并为未来的研究提出建议，为未来的研究铺平道路。
