过高的期刊自引会对期刊评价产生一定的误判现象,为了更好地了解我国期刊的自引情况,文章以2013—2015年版中国知网《中国学术期刊影响因子年报(自然科学与工程技术)》(统计年为2012—2014)的数据为基础,对我国63个学科、4 000左右的期刊的自引率采用统计方法进行了分析。结果表明:63个学科期刊平均自引率主要分布在0.05~0.20之间,物理学和文学学科表现出过高的自引率,63个学科期刊平均自引率在3个统计年中表现出相似分布的特点,频数分布呈现正态性,自引率在不同统计年之间具有显著性差异,不同学科期刊平均自引率之间也具有较大差异性,并且不同学科自引率的高低与学科期刊平均被引集中度呈负相关,高自引率的学科表现出学科的封闭性和不交叉性。
In order to get a better understanding of the self-introduction of journals in our country, the article takes the 2013-2015 edition of CNKI “Annual Report of Impact Factors of Chinese Journals (Natural Science and Engineering Based on the data of ”Technology" (Statistical Year 2012-2014), the self-introduction rates of 63 academic disciplines and 4,000 journals in our country were statistically analyzed. The results showed that the average self-citation rates of 63 academic journals ranged from 0.05 to 0.20, the self-citation rates of physics and literature showed too high, and the average self-citation rates of 63 subject journals showed similar distributions in three statistical years Characteristics and frequency distribution showed normality, self-cited rate in different statistical years with significant differences between different disciplines, the average self-citation rate also has great differences, and the different subject self-citation rate and the average periodicals cited The degree of concentration was negatively correlated, and the subjects with high self-introduction rate showed closed and non-intersectant subjects.
