Influence of journals indexed by SCI on Chinese journals based on the published articles from 2000 to 2009

The study was designed to investigate the influence of journals indexed by Science Citation Index(SCI) on Chinese journals.Data of articles included into Chinese Scientific and Technical Paper and Citations Data(CSTPCD) from 2000 to 2009 were searched.Totally 31 040 articles from China were published by journals indexed by SCI-E in 2000,and the number of them increased every year.In 2009,126 249 articles were indexed by SCI-E,306.73% higher than those of 2000.The increasing rate was 116.53% higher than that of articles published in the journals indexed by CSTPCD(190.20%) in the same period.From 2000 to 2009,the geometric mean of increase in the number of published articles from China indexed by SCI-E was 16.86% but it was 11.24% in CSTPCD.The number of the articles indexed by SCI-E increased year by year,much faster than that of CSTPCD.However,it does not necessarily mean the increase in impact.The authors of this paper suggest that we should restrict the paper publishing in the journals with IF≤3 and encourage the publishing in the journals with IF5.
