图书情报学SSCI期刊被引能力差距及收敛性研究

Study on Disparity and Convergence of SSCI Journals' Citation Competency in the Field of Information Science and Library Science

运用核密度估计方法、Dagum基尼系数、收敛方法 (α收敛、β收敛、俱乐部收敛),采用篇均被引频次为衡量指标,分析2001-2013年37种图书情报学SSCI期刊被引能力差距及其收敛性。研究结果显示:同一组内期刊被引能力差距不明显,不同组间期刊被引能力的差距较突出期刊;被引能力差距存在α收敛,但是收敛趋势不显著;存在显著绝对β收敛,不存在条件β收敛。高、中、低被引能力期刊组均存在俱乐部收敛。

Using kernel density estimation method, Dagum Gini coefficient, and convergence method （alpha, beta and club conver- gence）, this paper takes average citations per paper as the measure index to measure the cited competency gap and its convergence of 37 SSCI journals in the field of information science and library science during the period of 2001-2013. The conclusions are followings： The disparity of cited competency is not obvious within the same set of journals; the cited competency gap among different groups is obvious. The cited competency gap prevents alpha convergence trend with no significant. There exists a significant absolute beta convergence, no conditional beta convergence. A club convergence is found in the groups of high, medium and low cited journals.
