基于社会网络分析的合成生物学合著网络研究

A Social Network Analysis of Research Collaboration in Synthetic Biology

以美国科学引文索引数据库扩展版数据库(SCI—EXPANDED)收录,发表于2006—2011年的2 119篇合成生物学相关的论文题录为对象,通过对著者所属国家/机构所构成的合著关系分析,在一定程度上揭示了合成生物学这一新兴领域中不同国家/机构在科研合作中所发挥的作用。研究发现:大部分论文发表数量较多的国家/机构在合著网络中处于较核心的地位,少数国家/机构具有非常明显的合作优势,而部分国家/机构的在合作网络中的地位与其论文数量规模并不相称。同时,该领域的合作中国家/机构层面均存在一些合作关系紧密的小团体。

Based on the theory of social network analysis, this paper analyzes the pattern of research collaboration in global synthetic biology using co-authorship data from 2 119 articles published in 2006-2011 and collected by the SCI-EXPANDED database. The empirical study shows that most countries/organizations with a large number of publications are playing a key role in co-authorship networks, while a few countries＇/ organizations＇ status in the networks doesn＇t match to their performance in publication. In addition, the study reveals a few groups with close collaboration relationship both in country network and organization network.
