摘要：合作发表论文对于资源共享、思想交流、知识传播、信息获取等方面都具有重要的意义。本文收集并整理了2004到2008年《科研管理》的作者合作情况，构建了作者合作网络。然后，利用社会网络分析方法（SNA）对整个合作网络进行了小团体分析、集聚程度分析和中心性分析。结果显示，(1)整体网络是连通的，(2)小合作团体的规模都较小，(3)整体网络和小团体网络均具有无标度网络特征。

Abstract: Co-authoring papers are of great importance to sharing resources, exchanging ideas, spreading knowledge, acquiring information, and so on. The author cooperation situation of the journal, Science Research Management, from 2004 to 2008 is collected and arranged and a network of co-authors is established. And then, Social Network Analysis (SNA) is used to analyze the subgroups, network density, and centrality of the entire co-author network and the results show that (1)the entire co-author network isn’t connected, (2)the sizes of the cooperation subgroups are small, and (3) the entire co-author network and those subgroups are scale-free networks.
