“985工程”高校校际科研合作网络研究

Study of scientific collaboration networks in Project 985 Universities

本文收集了我国39所"985工程"高校在WoS和CNKI数据库中从1996年—2011年共16年每年的校际合作发文数量,运用复杂网络与社会网络分析方法,从整体、个体和社区三个方面分别对国内和国际期刊校际科研合作网络的科研合作网络图、发文量和合著率、节点度、点介数、核心-边缘结构和社区结构进行了对比分析。研究表明,"985工程"高校在国内外期刊都建立了广泛的科研合作,在国内期刊的科研合作从08年开始下降,高校在国际期刊的科研合作持续增多且有比较高的合著率。清华大学、北京大学和浙江大学在国内和国际期刊的科研合作网络中处于核心位置,且很有影响力。高校在国内期刊的科研合作网络主要是以清华大学和北京大学为中心、以上海交通大学和南开大学为中心的两个社区,而国际期刊的科研合作网络主要是以北京大学、南京大学和浙江大学为中心的一个社区。

This paper collects the number of intercollegiate cooperation between Project 985 universities,from 1996 to 2011 in the WoS and CNKI databases. By using complex network and social network analysis methods,the study conducts comparative analysis of the intercollegiate scientific research collaboration network,from three aspects- the whole( scientific cooperation network,number of published papers and co- author rate),individuals( node degree,betweenness and the core- periphery structure) and communities- of domestic and international journal. The results show that Project 985 universities have established extensive relationship in domestic journals and international journals. Scientific research collaboration in domestic journals of Project 985 universities has a downward trend since 2008,while that in the international journal continues to increase and co- authored rates are relatively high. Tsinghua University,Peking University and Zhejiang University are at the core position in both scientific research cooperation networks in domestic journals and international journals,and are very influential. Scientific research cooperation network in domestic journals is mainly based on two communities- Tsinghua University and Peking University centered and Shanghai Jiaotong University and Nankai University centered respectively. But in international network,the network is mainly based on one community,of which Beijing University,Nanjing University and Zhejiang University are in the center.
