我国高校科研合作的变化趋势:复杂网络分析的视角

Complex Network of Scientific Research Collaboration in China’s Higher Education Institutions

本文在Web of Science合作发表数据的基础上(包括A&HCI、SSCI以及SCI EXPANDED论文),利用复杂网络分析,计算了我国110所'211院校'的度中心性、近中心性、介中心性指标,并讨论了不同层次、专业类型、区域高校之间这些指标的分布差异,以及它们在最近几十年的变化趋势。文章的主要发现是:从分布差异上看,我国'985院校'在合作网络中处于核心地位,而且,综合院校以及东部院校也是如此。从变化趋势上看,我国高校的科研合作网络直到本世纪初才逐渐形成,并且理科的合作网络已经先于文科网络进入了成熟阶段。

Based on the data provided by Web of Science(including A&HCI,SSCI and SCI EXPANDED publications),this article uses the complex network analysis to calculate the indicators of degree centrality,closeness centrality and betweenness centrality of 110'211 project universities'in China,and then discusses the differences of these indicators between universities differentiating from each other in terms of their levels,specialized types,and regions,as well as their developing trends in recent decades.The main findings are:First of all,from the perspective of distribution differences,China’s'985 project universities'are at the core of the cooperative network,so are the comprehensive institutions and Eastern institutions.Secondly,from the perspective of developing trends,it’s not until the beginning of 21 st century that the research cooperation network of Chinese universities take shape,within which the cooperation network of sciences research has passed into the mature stage ahead of that of arts,humanities,and social sciences research.
