Abstract: 近年来,智库建设研究已经成为中国社会各界都十分关注的热门领域。为此,笔者谨从文献计量学角度分析智库研究的发展态势,以期为中国特色新型智库建设提供理论参考。文章以1961年至2016年中国知网CNKI数据库中智库研究相关学术论文作为样本数据,通过文献计量学结合可视化分析软件CiteSpace,对中国智库研究的现状以及未来发展趋势进行宏观分析。研究认为,由于党中央高度重视智库建设的推进工作,近年来中国智库研究在文献数量、期刊分布、研究群体、传播载体以及研究热点等方面呈现出了新的发展态势和最新进展,反映了中国新型智库的发展脉络及阶段性特征。
Recently various circles of society in China are concerning about think tanks construction research.This paper analysed the status of China's think tanks construction based on bibliometrics.We hope the research could supply references for the construction of new types of think tanks with Chinese characteristics.Taking academic papers which are related to think tank construction from China National Knowledge Infrastructure (CNKI) database between 1961-2016 as sample, by using bibliometrics and visualizing CiteSpace, this paper analyzed the status and development trend of China's think tank research.The study shows that, due to the central leaders' high attention to impel think tank construction, in recent years there are significant improvement and development in related articles, related journals, research groups, communication carriers and research hotspots of think tanks, showing the development and phased features of China's new types of think tanks.
