摘要
介绍了SCImago Journal Rank(SJR)及其计算过程,使用因子分析、回归及相关分析等方法实证研究了SJR与期刊影响因子、期刊h指数的关系。结果表明:SJR与期刊影响因子和期刊h指数均有较强正相关性;SJR与期刊影响因子的联合判定可区别出期刊在流行与声望两个维度上的特点;SJR和期刊引文及参考文献的平均性指标具有较强内部关联性,而期刊h指数则与总体性指标内部关联较强。提出了标准化SJR用于解决SJR不能跨学科比较的问题,提出了期刊声望演化指数用于衡量期刊声望的演变趋势,并将SJR的运用范围扩展到了学科和国家层次。
SCImago Journal Rank (S JR)and its determination are introduced. We have empirically analyzed the relationship between SJR and journal Impact Factor, h-index by the factor analysis, regression and correlation analysis. The results show that SJR has a significant positive correlation with journal impact factor and h-index. Combining SJR and journal impact factor, we can distinguish between journal's popularity and prestige characteristics. In addition, a strong internal relationship between S JR and the average indices of journal citation and reference has been found,and journal's h-index has strong internal relationship with overall indices. Further, standardized SJR (SSJR) and Journal Prestige Evolution (JPE) have been presented, which can be used to compare journals of different subjects and to analyze the trend in evolution of journal reputation. Moreover, application scope of SJR can be extended to the discipline and state level.
