中日印韩四国2011—2015年国际顶级期刊论文产出状况及国际地位对比分析

Research on Paper Output from International Top Journals between in China,Japan,India and South Korea during 2011—2015 and Their International Ranking

为了研究科研成果高水平论文产出状况,了解中日印韩四国近五年在国际顶级期刊(Cell、Nature、Science,CNS)论文产出以及国际地位变化,利用Web of Science统计2011—2015年中日印韩在CNS论文产出情况和国际地位变化。研究发现:我国与日本并驾齐驱,并大有赶超日本的趋势,二者约占四国论文总数的80%;印度和韩国仅占20%。国际排名则中日较为靠前,期间中国增长最为迅速,印度和韩国保持相对稳定,日本增长最低。我国2011—2015年CNS论文产出增长势头明显,相关系数呈正相关,并在2015年全面超越日本并进一步拉开差距,在四国当中首屈一指,但以后可能进入一种新常态模式,为此提出两点建议期望能保持高质量论文中高速增长。

In order to study the situation of high-level research articles in China, understand the recent 5 years papers published on Cell, Nature and Science from China, Japan, India and South Korea, this paper obtains the information on the paper output from the four countries in CNS and their situation of international ranking changes through the Web of Science database. Results indicate that China and Japan are neck and neck and China has a surpassing trend, the paper output from the two countries are accounted for 80% of the total four countries＇ output, while India and South Korea only accounted for about 20%. China and Japan have high ranking in international ranking, China has the fastest growth rate on the output in the five years, India and South Korea keep stable, Japan has the lowest growth. China has obvious growth trend in CNS output during 2011--2015, of which the correlation coefficient indicates that a positive correlation between paper output and time. In addition, China has already completely surpassed Japan in 2015 and widen the difference between them. Now China stands out as the output in CNS in the four countries, but its growth model maybe come into a new normal state soon. For this reason, two suggestions are given to maintain a medium-high rate of growth on high-quality papers.
