基于知识图谱的国际知识创新研究可视化分析

以2002—2021年Web of Science 核心数据库中知识创新领域的1999篇文献作为数据样本，运用 CiteSpace软件对相关文献进行科学计量分析，并绘制知识创新研究领域的国家和机构分布、研究热点和趋势的知识图谱。结果显示，知识创新研究成果不断增多，美国、中国、英国、西班牙和意大利等国家在知识创新领域产出总量丰富。主要从研究主体、研究内容、影响因素3个方面分析热点关键词，企业间多以合作形式进行知识创新。最后，对未来的研究方向加以分析和总结。

The Information Visualization Analysis on International Knowledge Innovation Research Based on Knowledge Graph

1999 literatures in the field of knowledge innovation from 2002 to 2021 in the Web of Science core database are taken as data samples, and CiteSpace software is used to make a scientometrics analysis of relevant literatures, and a knowledge map of the distribution of countries and institutions, research hotspots and trends in the field of knowledge innovation is drawn. The results show that the research achievements of knowledge innovation are increasing, and the total output of the United States, China, The United Kingdom, Spain and Italy is abundant in the field of knowledge innovation.The hot keywords are analyzed from three aspects: research subject, research content and influencing factors. Enterprises mostly carry out knowledge innovation in the form of cooperation. Finally, the future research direction is analyzed and summarized.
