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。
Based on more than 210,000 articles on international cooperation in science in China collected by SCI-E, SSCI and A & HCI from 2002 to 2011, the author studies the number, nationality, subject areas, periodicals, etc. of international cooperation in scientific research in China using metrology and network analysis methods Change, distribution and cooperation network. The results showed that the number of international cooperation papers in China increased rapidly, but there was no obvious change in the international cooperation degree and the average author. The cooperation papers between China and advanced countries in science and technology accounted for more than 80% of all international cooperation papers. Physics, Physics, Multidisciplinary, Space Science and other disciplines have a relatively high influence. According to the cooperation network, the United States is the largest and most important cooperative partner in China. All of ESI’s 22 disciplines collaborate, accounting for 30% of all collaborative essays, and Physics is the subject of the most collaborative countries.
