高校已经成为国家科技创新体系中的重要组成部分,随着科研活动集体化趋势不断增强,高校之间的科研合作日益增多,有关高校科研合作问题的研究具有重要的理论价值和现实意义.本文选取我国39所"985工程"高校作为研究样本,借鉴社会网络分析工具和方法,从整体网络分析、网络密度分析、核心-边缘结构分析、网络节点中心性分析等几个方面对高校之间的科研合作关系进行全方位、多角度的计量分析.研究结果表明,我国39所"985工程"高校之间已经初步建立了广泛的科研合作关系,但合作强度还有待于提高.另外,各个高校的发文量与其度数中心性存在显著的正相关关系,表明加强科研合作能够在一定程度上提高高校的科研产出数量.%Universities have become the main component in the national scientific innovation system. As the collaboration between different universities strengthens, the study on the scientific research collaboraLion is of increasingly vital value and importance. This paper chooses the "985 Project" universities as the sample to study on their scientific research collahoration relationship from the perspective of co-auchorship based on the methods and tools of Social Network Analysis. The research results illustrate that the 39 universities has already established the primary scientific research collaboration, but the intensity still waits for enhancement. Besides, there exists significant correlation between sciencific output and scientific collaboration. It means that to some extent to strengthen collaboration intensity can improve the quantity of universities ' scientific output.
