[目的/意义] 对数字图书馆进行分类甄别，运用内生增长理论构建数字图书馆内生价值及其知识外溢效应基本模型。[方法/过程] 将国内外数字图书馆划分为开发、存储、应用三大环节和七大模块，对其进行内生变量实证分析和整体分析。[结果/结论] 数字图书馆网络系统知识外溢具有全球效应。

[Purpose/significance] This paper aims at screening the digital library and constructing the basic model of the endogenous value as well as its knowledge spillover effect on the digital library with the theory of endogenous growth. [Method/process] The digital library was divided into development, storage, application and seven parts at home and abroad. We made an overall analysis and empirical analysis on endogenous variables. [Result/conclusion] It is concluded that the knowledge spillover of the digital library network system has global effects.
