在对知识扩散的概念及其相关研究应用进行回顾的基础上,本文阐述了基于期刊引证关系的学科知识扩散广度、强度以及速度等指标的内涵与计算方法,并给出了三者的计量公式及其相互关系。最后以图书馆、情报、档案学为例,对其知识扩散广度、扩散强度和扩散速度知识进行了实证研究;研究结果显示,期刊知识扩散指标是一个能够广泛应用在科学评价、产业研究、技术创新研究等领域的重要工具。
Based reviewing the concept,related researches and applications of knowledge diffusion,the paper expounded discipline knowledge diffusion breadth,strength and speed indexes such as connotation and calculation methods through the journal citation relations.And gave the formulas of the three indexes including their relationships.Finally,there is a case study on the library,information,archive science,it carried out an empirical research on the diffusion breadth,diffusion intensity and diffusion speed of the library,information and archive science knowledge.It is showed in this paper that Journal Knowledge Diffusion Index is an important tool can be widely applied in scientific research evaluation,industry and technology innovation research fields and so on.
