为研究P指数对期刊绩效评价的效能,并探讨其与传统评价指标之间的关系,采用统计学方法,以2008-2012年CSSCI收录图书情报类核心期刊为研究对象,考察了P指数与h指数、五年影响因子、被引频次等传统文献计量学指标的关联关系。结果表明:P指数与被引频次、平均被引率、五年影响因子相关性显著,与h指数具有一定相关性。在此基础上,建立了P指数与五年影响因子、h指数的回归方程。
In order to study the effectiveness of P index on periodical performance evaluation and discuss the relationship between P index and traditional evaluation index, using statistical methods, taking CS Library’s core journals of Library and Information Science from 2008 to 2012 as the research object, Index, five-year impact factor, cited second-order traditional bibliometric indicators of the association. The results show that there is a significant correlation between P index and citation frequency, average lead rate and five-year impact factor, and some correlation with h index. On this basis, the regression equation of P index and five-year impact factor and h index is established.
