为深入揭示我国专利研究论文的主要学术知识群和研究热点,采用关键词词频分析和共词分析方法,以CSSCI为数据源,对1998-2009年专利研究论文进行分析,统计出反映专利论文研究热点的高频关键词42个,并利用因子分析和多维尺度分析方法,绘制我国专利论文的研究热点知识图谱。在此基础上,进一步探讨我国专利论文的研究现状,指出研究的重复之处并预测未来的研究方向。
In order to reveal the major academic knowledge groups and research hotspots of Chinese patent research papers in depth, we use keyword frequency analysis and co-word analysis methods to analyze the patent research papers from 1998 to 2009 with CSSCI as the data source, 42 high-frequency hot keywords, and the use of factor analysis and multidimensional scaling analysis method, the drawing of China’s patent research hotspots knowledge map. On this basis, we further explore the current situation of the research on patent papers in our country, point out the duplication of the research and predict the future research direction.
