2006-2010年我国预防医学与卫生学类期刊自引率分析

The Self-citation of Chinese Periodicals on Public Health and Preventive Medicine,2006-2010

目的了解我国预防医学与卫生学类期刊的自引情况,为探讨自引对我国科技期刊评价的影响。方法根据2007-2011年版《中国科技期刊引证报告(核心版)》(CJCR)公布的我国科技期刊及其预防医学与卫生学类期刊他引率的数据,统计自引率。并对不同影响因子和总被引频次预防医学与卫生学类期刊的自引率进行了统计分析。结果我国预防医学与卫生学类期刊平均自引率由2006年的0.1971上升至2010年的0.219 0;高自引期刊由2006年34.29%,逐年上升到2010年的46.27%。同时2006-2010年预防医学与卫生学类期刊影响因子处于中间水平,或者总被引频次最低的期刊的平均自引率比较高。结论 2006-2010年我国预防医学与卫生学类期刊的自引率不降反而有升高的趋势,预防医学与卫生学类期刊的自引率相对较高,应当重视其过度自引现象。

Objective To explore the effect of self-citation on sci-tech journals evaluation. Methods The data of self-cited rate of Chinese journals on public health and preventive medicine （CJPHPM） was collected from Chinese S＆T Journal Citation Reports （CJCR） published in 2007 -2011. Based on these data, the self- citation of CJPHPM were analyzed. Results The self-cited rate of CJPHPM presented an upward trend in the year from 2006 （rate =0. 1, 971） to 2010 （rate =0. 2, 190）, and journals with high self-citation took an ascending portion from 2006 （34.29%） to 2010 （46.27%）. The IF of the journals stayed at a middle level though 2006 to 2010, and the journals with the lowest total citations had a comparatively high self - cited rate. Conclusion An up - trend was observed in the self-citation of CJPHPM in 2006 - 2010, which should be alertly noticed with aspect of excess self - citation.
