以中国知网(CNKI)和汤姆逊路透公司的Web of Science(WoS)收录的物理学学科的合作基金论文为研究对象,通过对合作类型多角度分析来对比中国在物理学领域的合作基金论文的分布情况。着重对合作基金论文的合作类型在资助类型和地区分布上进行比较研究。结果表明,合作基金论文在两个数据源上有不同的表现:CNKI的论文发表量先升后降,而WoS逐年上升;两个数据的合作优先顺序是一样的:国内机构内合作>国内跨机构合作>国际合作,其中CNKI的国际合作比例较少,而WoS比例为同期总量的1/5;北京地区依然在两个数据源的三种合作类型中占据明显优势,国内机构在参与国际合作的过程中具有高度的地域选择性;美国在国际合作中都能处于第一或第二的位置,表现比较稳定。
The research performance of top universities in China is revealed in this study and analyzed using the essential science indicators(ESI) database.Different types of bibliometric indicators are applied in this study,including publication output and impact indicators.This study finds that the academic performance of universities in China is advancing rapidly,with many universities coming out near the top of the rankings,especially in terms of quantity of papers.The quantitative performance of universities in China is remarkable.The research results show that there is a considerable gap between quality and quantity of research output at the top universities of China,with research influence concentrated on some specific fields for selected universities.Engineering,Chemistry and Material Science are the fields with relatively outstanding performance in the top universities.
