国际专利引文研究的计量分析

Informetrics Analysis of International Patent Citation Study

本文以共被引和共词分析方法,以SCI中2000年至2013年的有关专利引文的研究文献为对象,分析了其知识基础与研究主题。结果表明,专利引文研究主要是建立在Jaffe AB(1993)、Narin F(1997)、Griliches Z(1990)和Trajtenberg M(1990)等人研究基础之上,核心研究领域集中在企业/产业的创新能力与绩效评价,涉及知识溢出、技术扩散、竞争优势等内容。关键词聚类在战略坐标中的象限分布则表明专利引文研究处于既定范式下的深度研究,缺少对范式扩展的广度研究。另外,研究还发现专利引文研究较少关注基础研究与应用技术间的互动关系。

Articles of patent citation from SCI between 2000 and 2013 were analyzed in this paper by co-citation and co-word analysis methods in order to explore their knowledge base and research topics. The results have shown that four classical papers written by Jaffe Ab in 1993, Trajtenberg M in 1990, Griliches Z in 1990,Narin F in 1997 respectively formed the key knowledge base for patent citation field. The main research topics concentrated on innovation, performance evaluation of industries or firms, including content of knowledge spillovers, technology diffusion, competition advantage, etc. Distribution of keywords clusters implied that patent study was deep research under given paradigm while lack of study on expanded paradigm. Moreover, the results of this paper indicated that few studies focused on relationships between basic research and applied technologies of patent citation study.
