| 中文摘要: |
| 基于2008—2013年Thomson Reuters发布的Journal Citation Reports (JCR)及中国科学技术信息研究所发布的《中国科技期刊引证报告》(CJCR),比较分析中外科技期刊载文量、总被引频次、影响因子、即年指标等各主要文献计量指标的变化。结果显示,我国被SCI收录期刊的数量和影响力指标近年来总体上呈上升态势,但年平均载文量却稍有下降,以中文期刊为主的CJCR收录期刊数量和年平均载文量均呈停滞增长甚至下降的趋势。这可能表明我国科技期刊的稿源竞争力有所下降。 |
| 英文摘要: |
| Based on Journal Citation Reports ( JCR) and Chinese Journal Citation Reports (CJCR) issued from 2008 to 2013, we comparatively analyzed the annually published articles, total cites, impact factor, immediacy index and cited half life for scientific journals from China and abroad. Our results indicate that numbers and impacts of China's SCI journals have been steadily increasing in recent years, while the annual average number of published articles of China's has been slightly decreasing. We conclude that for China's journals, the competitiveness of high-quality manuscripts may have declined in recent years. |
