基于专利引用的技术领域主题的知识流动时间研究

Research on the Knowledge Flow Time about Technology Field Subject from the Perspective of Patent Citations

将专利文献之间的引用关系作为知识流动的研究途径。首先,从专利文献前引和后引的角度入手,建立分别代表科学知识、技术基础知识和技术前沿知识的数据集;然后,运用共被引聚类法建立基于技术领域主题的知识流动链条;最后,基于科学知识吸收时间和技术知识扩散时间两个维度,构建技术领域主题的知识流动时间模型,以期从微观的角度观察技术领域主题的科学与技术发展趋势,并对后续的实证研究提供理论基础和方法基础。

This paper takes patent citations as the research approach of knowledge flow. First, from the perspective of forward citations and backward citations, we set up some data sets representing scientific knowledge, technical basic knowledge and technical frontier knowledge. Second, we build the chain of knowledge flow based on by using co-citation clustering; Finally, we build knowledge flow time model a- bout technology field subject based on scientific knowledge absorption time and technical knowledge diffusion time, so as to observe the de- velopment trend of science and technology of the technology field subject from the micro perspective , which provides theoretical basis and method basis for future empirical research.
