高影响力作者的机构分布模式研究

Research on the Distribution of High impact Author Among Institutions

高影响力作者是一个科研机构科研产出的主要力量,因此对作者的机构分布规律的研究是进行科研机构评价的主要内容之一。以ESI(Essential Science Indicators)的学科分类和机构与作者排名算法为参考,以Web ofScience的基础数据作为数据源,通过对作者和科研机构之间关系的深入分析发现,在研究所涉及的4个学科中,总体上80%左右的高影响力作者就职于总被引排名前1%的机构。基于机构分层的作者分布分析结果显示,三个层次的高被引机构所拥有的高影响力作者的比例均维持在比较稳定的水平。在此基础上,提出以机构拥有的高影响力作者的比例为指标的新的机构评价方法。

High impact authors are the fundamental forces in the scientific production for an institution. Hence research on the distribution of high impact authors among institutions is one of the main ways to evaluate an academic institution. According to subject classification and computing algorithms for authors and institutions in the Essential Science Indicators （ESI）, relations between authors and institutions in four disciplines have been explored and the result shows that generally 80% high impact authors work in 1% top cited institutions. Furthermore, quantitative analysis on the author distribution among hierarchical institutions indicates that the percentages of high impact authors distributing in three groups of high cited institution are at a stable level. Consequently a new strategy is proposed that the proportion of high impact authors that an institution possesses in a discipline can be applied to institution evaluation
