网络环境下图情学与管理学老化规律及其比较研究

Comparative Study on the Obsolescence of Library and Information Science and Management Science under the Web

选择基于网络的引文数据库CSSCI 2006-2009年间管理学和图书情报与文献学学科领域的33 4689条引文数据,进行两学科的负指数老化模型分析、老化指标分析。研究发现,在网络环境下,这两个学科都符合负指数的老化规律,管理学的学科稳定性要比图书情报与文献学好,而图书情报与文献学的老化速度要比管理学快。本文近似地计算出了目前阶段这两个学科的半衰期分别为4.64年、5.29年;普莱斯指数分别为0.54、0.47;最大引文年限分别为2年、3年。

This paper analyzed 334,689 citation data of CSSCI in Library Information and Philology Science and Management Science during 2006-2009, and conducted negative exponential aging model analysis, aging index analysis of the two disciplines. The study found that, under the network environment, both of the two subjects were consistent with negative exponential aging law. Of the two disciplines, Management was steadierwhile the aging speed of Library and Information discipline was faster. An approximate calculation showed that the half-life of these two disciplines＇ current stage is 4.64 and 5.29 years respectively, the Price index is 0.54 and 0.47, and the Maxi- mum length of citation is 2 years and 3 years.
