研究主题的知识流动测度及其实证分析——以H指数研究为例
发布时间：2018-07-18 20:27
【摘要】：[目的 /意义]通过量化计量指标对研究主题的知识扩散进行测度与分析,客观地展现研究主题所包含的知识单元的扩散路径及其扩散规律。[方法 /过程]以Web of Science(SCI-ESSCI)数据库核心合集为数据来源,通过被引参考文献检索方法,以J.E.Hirsch 2005年首次提出H指数概念的文献为被引文献,检索2005-2015间引用该文献的施引文献,得到样本数据。借助信息可视化分析工具CiteSpace分别进行关键词共现与文献共被引分析。将分析结果通过本文所提出的双阶知识扩散度指标Q算法进行计算,得到指标Q量变情况,并进一步分析H指数研究领域的演化扩散状况。[结果 /结论]H指数研究主题的知识扩散的相关性随着流动阶层的增加而降低;H指数研究主题一、二阶知识扩散文献的主要研究方向不同,二阶文献更侧重于应用领域的拓展,这也是该研究邻域知识流动的新增长点;通过对H指数研究主题的分析,证明了本文所提出的双阶知识扩散度指标Q的准确性及科学性。
[Abstract]:Objective / significance: to measure and analyze the knowledge diffusion of the research subject by quantitative measurement index, and objectively show the diffusion path and diffusion law of the knowledge unit contained in the research topic. [methods / process] based on the core collection of the Web of Science (SCI-ESSCI) database, through the method of citation literature retrieval, using the literature that J. E. Hirsch first proposed the concept of H index as cited literature in 2005, to retrieve the cited literature from 2005 to 2015, Get the sample data. With the aid of CiteSpace, a tool of information visualization analysis, keyword co-occurrence and literature co-citation analysis are carried out. The results are calculated by the two-order knowledge diffusivity index Q algorithm proposed in this paper, and the quantitative variation of the index Q is obtained, and the evolution and diffusion of H exponent are further analyzed. [results / conclusion] the correlation of knowledge diffusion in H index research subject decreases with the increase of flowing class. The main research direction of the second order knowledge diffusion literature is different. The second order literature focuses more on the extension of application field, which is also a new growth point of the study on the flow of knowledge in the neighborhood, and the accuracy and scientificity of the two-order knowledge diffusion index Q proposed in this paper are proved by the analysis of the research subject of H index.
