Self-citation behaviour of authors affiliated to an institution was studied through synchronous self-citation analysis. From 2004 through 2015, Web of Science and SciVerse Scopus databases indexed a total of 1503 articles by authors affiliated to a university in India. Self-citations were prevalent in 62.23 percent of works and significant difference is observed in self-citation pattern with regard to co-authorship, size of reference list, authors’ productivity, citation age, citation over time, and reputation of source publications. Statistically positive correlation is observed between number of co-authors and number of self-citations (p<.01). Inter-institutional collaborative works attract more self-citations than works of intra-institutional efforts (p<.01). Significant positive correlation exists between authors’ productivity and share of self-citations (p<.01). Regarding the currency of self-citations, authors tend to cite more of their recent works than the works of others. Articles published in Journal Citation Reports (JCR) indexed sources have more number of self-citations than articles published in JCR excluded sources (p<.01).

机构层面同步自引实践的盛行

通过同步自引分析研究机构作者的自引行为。从 2004 年到 2015 年，Web of Science 和 SciVerse Scopus 数据库索引了印度一所大学附属作者的 1503 篇文章。自引在 62.23% 的作品中普遍存在，自引模式在共同作者、参考文献列表的大小、作者的生产力、引文年龄、随时间的引用和来源出版物的声誉方面存在显着差异。在共同作者数量和自引数量之间观察到统计正相关（p<.01）。机构间的合作作品比机构内的作品吸引更多的自引（p<.01）。作者的生产力和自引份额之间存在显着的正相关（p<.01）。关于自引的流通性，作者倾向于引用更多他们最近的作品而不是其他人的作品。在期刊引文报告 (JCR) 索引来源中发表的文章比在 JCR 排除来源中发表的文章具有更多的自引次数 (p<.01)。
