基于国家、学科合作网络和期刊分布的中国科研国际合作研究

Study of Chinese International Research Collaboration Based on Network of Countries, Fields and Distribution in Journals

基于2002-2011年SCI-E、SSCI和A&HCI所收录的21万余篇中国科研国际合作论文,应用计量学和网络分析方法,研究了中国科研国际合作的数量、国别、学科领域、期刊等变化、分布以及合作网络。结果显示:中国国际合作论文的数量增长较快,但国际合作度、篇均作者等没有明显变化;中国与科技先进国家的合作论文占所有国际合作论文的80%以上;Social sciences领域的合作较少,Physics学科的合作最多,Molecular Biology&Genetics学科合作增长速度最快;Mathematics、Physics、Multidisciplinary和Space Science等学科的期刊影响力较高;根据合作网络,美国是中国最大和最主要的合作伙伴,在所有ESI的22个学科中均有合作,占所有合作论文的三成,而Physics是合作国家最多的学科。

Articles indexed in Thomson Reuters＇ s Web of Science （WoS） from January 1st, 2002 to De- cember 31th, 2011 were studied in order to describe the growth and distribution of Chinese international research collaboration （IRC）, from the view of amount, authors, countries, fields, journals, and to provide the collaboration network of countries and fields, using bibliometric and social network methods. The main results as follow： faster growth in the number of article, contrasted with the stable in average annual growth of IRC degree; the articles collaborated with Scientifically Advanced Countries （SAC） accounted for more than 80% of all IRC＇ s; as to the fields, collaboration in broad field of Social Science was at disad- vantage, the most field was Physics and the fastest field was Molecular Biology ＆ Genetics; the fields of Mathematics, and Physics, Muhidisciplinary journals and Space Science had higher influence in corre- sponding journals; according to the network, as the largest and most important partners, USA had 30% IRC articles, and collaborated with China in all 22 fields.
