基于SJR数据库的巴西、印度、韩国、中国科技论文比较分析

SCImago Journal & Country Rank-covered scientific papers published by Brail,India,South Korea and China: A comparative analysis

以SJR为数据来源,比较分析了1996-2008年巴西、印度、中国、韩国4个国家发表科技论文数量、可引用文献量、文献被引量、自引量、篇均被引量、去除自引后的篇均被引量、H指数、文献引用率、国际合作量等9个指标。中国发表论文数最多,2003年后每年增加约3万篇。巴西、韩国文献引用率、篇均引用量高,且自引率低;印度居中等水平;中国文献引用率、篇均引用率低且自引率高;国际合作度巴西最高、中国最低。可见中国的科技论文质量与其他3个国家相比,还有一定的差距。

The number of papers, citable papers, cited papers, self-citations, citations per paper, citations per paper after exclusion of self citations, H index, citations of papers, and times of international collaboration in SCImago Journal ＆ Country Rank （ S JR）-covered scientific papers published by Brail, India, South Korea and China were analyzed. The number of papers published by China was the highest with an annual increase of 30 000 papers since 2003. The number of total citations and citations per paper of scientific papers published by Brail and South Korea was high with a low rate of self-citations followed by India. The number of total citations and citations per paper of scientific papers published by China was low with a high rate of self-citations. The times of international collaboration were the highest in Brail and the lowest in China, indicating that there is certain gap in the academic levels of papers between China and the other 3 countries.
