6种力学类中文核心期刊作者自引的统计分析

Statistics and Analysis of Author Self-citation of 6 Mechanics Core Journals

为探讨作者自引的规律,对6种力学类中文核心期刊所载论文的作者自引量进行统计分析。结果表明,58.28%的论文存在作者自引,篇均作者自引频次为1.35次,呈现出较普遍的作者自引现象;EI收录期刊论文和基金项目资助论文的作者自引量明显高于非EI收录期刊和非基金项目资助论文;作者自引量与期刊的基金论文比、平均引文数和影响因子指标呈一定的正相关性,而与论文的作者人数则无相关性。

In order to study the laws of author self - citation, the author self - citation quantity of papers of 6 mechanics core journals is counted and analyzed. The results show that the author self- citation is universal in mechanics papers; the self- citation rate is 58. 28% ; the average self- cited is 1. 35. The author self- citation quantity of EI journals ＇ papers and funded papers are much more than the non - EI and unfunded papers. There is a positive correlation between the author self- citation quantity and the rate of fund papers, average number of citation, impact factor of journals. But there is no eolTelation between author self - citation quantity and the number of authors.
