基于Scopus的SJR指数分布规律研究

Study on the Distribution Law of the SJR Indicator Based on the Scopus

以统计学方法分析了Scopus收录期刊SJR指数的分布规律。研究表明,期刊SJR指数的分布具有稳定性和动态性的特征,数据表现出集中与分散的规律。SJR指数的理论值与期刊序号间的关系可用回归方程:y=kxb来表示,这个方程与实际数据的拟合度很高。SJR指数的理论值与期刊数量、期刊所在学科等等因素有关。

The paper studied on the distribution law of the SJR indicator based on the data from the Scopus database used the method of statistical.Results show that the distribution of the SJR indicator appeared the stability and dynamic characteristics and the data followed the centralization and dispersion law.The theory data of the SJR can express with the regression equation：y=kxb and the equation can fairly fit the actual data.The data of journal＇s SJR connected with the journal＇s quantities,subject and other factors.The distribution the SJR indicator accorded to the Bradford＇s Law of Scattering.
