《中华内科杂志》被引频次的影响因素分析

目的 分析发表于《中华内科杂志》2008-2010年所有学术性文章的属性和被引情况,以探讨影响《中华内科杂志》影响因子(IF)的因素.方法 检索并套录中国生物医学期刊引文数据库(CMCI)中收录的《中华内科杂志》 2008-2010年的所有文献,手工统计文献各相关因素并进行分层比较.结果 《中华内科杂志》3年共发表1164篇学术性文献,篇均参考文献9.95条,总被引频次为1029次,其中篇均被引0.93次/篇,面均被引0.31次/面,零被引文献736篇,占发文总数的63.2％.论著类、纯临床类的文献有较好的引文产出.在基金资助方面,无基金资助的研究比有基金支持者有更好的产出.血液病学、心血管病学、胃肠病学是统计年中发文量最多的3个专业,而内科领域亚专业中的重症医学、急诊医学和肾脏病学发文量最少；虽然各学科间引文情况存在固有差异,但仅就引用绝对值看,引文产出较好的是神经/精神病学(篇均被引0.73次)、心血管病学(0.65次)和胃肠病学(0.54次),而血液病学、基础医学和风湿病学对IF的贡献相对不足.结论 加强优秀论文的组稿和宣传力度,减少零被引文献的数量,扩大显示度,提供更快捷和便利的文献阅读方式是编辑部下一步工作的重点.

An analysis of impact factor of Chinese Journal of Internal Medicine from 2008 to 2010

Objective To analyze the articles and citation published in the Chinese Journal of Internal Medicine from 2008 to 2010, in order to investigate the influence factors of impact factor (IF).Methods All articles published in the Chinese Journal of Internal Medicine covered by Chinese Medical Citation Index(CMCI) from 2008 to 2010 were searched and downloaded. Some article related attributions were manual added and their influences to IF were analyzed.Results A total of 1164 academic papers were published in the journal in 3 years, with 9.95 references per paper. The total citation was 1029 times, with 0.93 time per paper and 0.31 time per page. Among them, 736 articles were not cited, accounting for 63.2%. Original articles, pure clinical articles had good citation output. For fund supporting, the citation of articles without fund was higher than those with fund. The articles on hematology, cardiology and gastroenterology accounted the most, while ICU, emergency and nephrology were the least internal medicine reported specialties.Although there exists citation difference among different subjects, for considering the absolute values, neurology/psychiatry (0.73 time per paper), cardiology (0.65 time per paper) and gastroenterology (0.54 time per paper) had better citation output, while hematology, basic research and rheumatology had no good performance to IF.Conclusion We should further strengthen acquisition and dissemination of excellent articles, reduce the number of non-cited paper, expand periodical visibility, and provide a quick and convenient way of literature reading.
