摘　　要：针对Z指数不能实现跨学科领域期刊评价的缺陷,文章通过引入学科规范化引文影响力修正不同学科的引用差异,改进Z指数并提出ZCNCI指数。通过分析ZCNCI指数与Z指数、P指数、SNIP、标准化特征因子、影响因子百分位等指标的相关性和差异性,验证ZCNCI指数跨学科期刊评价的效力。结果表明,ZCNCI指数延续了Z指数综合反映期刊数量、质量和被引分布特征的优势,与Z指数、P指数、标准化特征因子的相关性较高,且克服了SNIP、影响因子百分位的评价缺陷,在跨学科期刊评价中的综合表现较好。ZCNCI指数具有跨学科期刊评价效力,可用于跨学科期刊评价。This paper presents a new calculation method for the Z index to overcome the problem that the Z index cannot adequately evaluate interdisciplinary journals.This paper introduces the CNCI indicator to correct the differences in citation behavior in different subject areas and proposes a new ZCNCI index.By analyzing the relevance and differences among the ZCNCI index,Z index,P index,SNIP,normalized Eigenfactor and impact factor percentile indicators,the effectiveness and feasibility of ZCNCI index can be verified.The ZCNCI index keeps the advantages of Z index by comprehensively reflecting the quantity factor,quality factor and cited distribution characteristics,and it has a high correlation with the Z index,P index and normalized Eigenfactor.These indicate the effectiveness of ZCNCI index on interdisciplinary journal evaluation.On the other hand,the ZCNCI index overcomes the shortcomings of SNIP and impact factor percentile indicators.Therefore,it has the best overall performance in the evaluation of interdisciplinary journals.
