对数字图书馆著作权评估的重要性进行分析,对传统著作权评估方法进行比较,选用基于收益法基础上产生的收益提成率法来评估数字图书馆著作权的价值。结合AHP方法确定带来超额收益的相关因素,通过构建一个指标体系系统来确定无形资产收益权重,全面、综合地衡量数字图书馆著作权的价值。 This paper analyzes the importance of the digital library copyright evaluation, compares the traditional copyright evaluation methods, and selects the revenue royalty rate method based on the income method to evaluate the value of the digital library copyright. Combined with the AHP method to determine the relative factors that cause excess returns, we construct an index system to determine the weight of return on intangible assets, and comprehensively and comprehensively measure the value of digital library copyright.
