中国科研产出2020年或赶超美国
英国皇家学会3月28日发布了一份名为《知识、网络和国家：21世纪的全球科研合作》的报告。报告显示，中国的科研论文发表数量从第六位上升到全球第二。尽管排在前十名的很多都是西方大国，但它们发表的研究论文数量正在减少，中国、巴西、印度等国发表的研究论文越来越多。到2020年，中国科研产出有可能超过美国，成为世界第一。[p=30, 2, left]该报告对全球所有国家发表的科研论文的多项数据进行了分析，并对各国在1993—2003年和2004—2008年这两个时间段的论文数量进行比较。结果显示，美国在科研论文数量上仍是世界第一，但其所占比重下降了5个百分点；中国所占比重则从4.4%上升到了10.2%。[/p][img=618,2]http://www.chinadaily.com.cn/language_tips/news/attachement/jpg/site1/20081224/00221910dbbd0abbebf30e.jpg[/img][table=0,#ffffff]
