期刊的跨学科引用对跨学科知识输出的影响研究——以图书情报领域为例

Research on the Impact of Periodical Interdisciplinary Citation on Interdisciplinary Knowledge Output——Taking Library and Information Science for Example

[目的/意义]探讨期刊的跨学科引用对跨学科知识输出的影响,一方面有利于促进学科之间的知识流动,另一方面分析期刊在跨学科交流中的作用。[方法/过程]用参考文献多样性指数(RDI)测度期刊的跨学科引用;以篇均被引频次表示期刊跨学科知识输出强度(IK),以基于普赖斯指数的被引及时性指标(A_(i))与基于平均时间的被引速度指数(AS_(i))共同表示期刊跨学科知识输出时效性(TL),以引证文献多样性指数(CDI)表示期刊知识输出跨学科性,从输出强度、时效性、跨科学性三个维度分析跨学科引用对跨学科知识输出的影响。[结果/结论]以图书情报学18种CSSCI期刊数据为样本,研究发现:跨学科引用有助于拓宽知识输出的学科范围,提高本学科在其他学科内的影响力,但不利于及时进行跨学科知识输出。

[Purpose/Significance]This article discusses the influence of journals'interdisciplinary citations on the output of interdisciplinary knowledge.On the one hand,it is helpful to promote the flow of knowledge between disciplines.On the other hand,it analyzes the role of journals in interdisciplinary communication.[Method/Process]Reference diversity index(RDI)is used to measure journals’interdisciplinary citations;the interdisciplinary knowledge output intensity(IK)of journals is expressed by the frequency of citations,the citation timeliness index(A_(i))based on price index and the citation speed index(AS_(i))based on average time are used to express the timeliness of journal interdisciplinary knowledge output(TL),the citation diversity index(CDI)is used to express the interdisciplinary nature of journal knowledge output,and the impact of interdisciplinary citations on the output of interdisciplinary knowledge is analyzed from the three dimensions of output intensity,timeliness and inter-scientificity.[Result/Conclusion]Based on the data of 18 CSSCI journals of library and information science,the research finds that interdisciplinary citation helps to broaden the scope of knowledge output and increase the influence of the discipline in other disciplines,but it is not conducive to timely interdisciplinary knowledge output.
