摘要:

【目的】分析P指数在中国SCI期刊评价中的适用性,从而促进中国SCI期刊评价体系的完善。【方法】以中国大陆及香港地区SCI期刊在2014年度《期刊引证报告》(Journal Citation Reports,简称JCR)的主要文献计量指标为研究对象,系统研究P指数分别用于不同学科和同一学科中国SCI期刊评价的有效性,分析P指数与被JCR收录后的总被引次数(C)、影响因子(IF)、5年影响因子(IF5)、被JCR收录后的总载文量(N)和平均被引率(C/N)的关系,并进行相关性分析。将P指数和h指数对中国SCI期刊评价的适用性进行对比。【结果】P指数与中国SCI期刊的总被引次数、影响因子、5年影响因子、总载文量、平均被引率具有较强的相关性,能够较好地反映期刊的规模和影响力。P指数对同一学科SCI期刊比不同学科SCI期刊的评价更具优势。【结论】P指数延续了h指数的优点,并具有更强的区分度,对优秀学术期刊的识别能力比较突出,使期刊评价更加科学,具有更加广泛的实用意义。

Abstract:

[Purposes] The applicability of P index in Chinese SCI journal evaluation was analyzed so as to promote the perfection of the evaluation system of the Chinese SCI journal.[Methods]Based on the Journal Citation Report(JCR) main bibliometric indexes of SCI-covered journals published in Mainland China and Hong Kong Area from their included year to 2014,the P index was calculated precisely,the effectiveness of P index used for the evaluation of Chinese SCI-covered journals in different disciplines and the same discipline were studied systematically.The relationships between P index and total citations(C),impact factor(IF),5-year impact factor(IF5), paper number(N), average citation rate(C/N) were analyzed by the correlation analysis.The applicability of P index and h-index used for the evaluation of Chinese SCI-covered journals were compared.[Findings] P index has strong correlation w ith total citations, impact factor, 5-year impact factor and average citation rate; therefore, P index can reflect the scale and influence of the journals.The evaluation of P index used for SCI journals in the same discipline is better than that in different disciplines.[Conclusions] P index extends the advantages of the h-index, and has a stronger discrim ination.P index can identify outstanding Chinese SCI-covered journals, and make journals evaluation more scientific.Therefore, P index has extensive practical significance for the evaluation of Chinese SCI-covered journals.
