摘　　要：本文分析了数字保存项目存在的延迟期权,构建了基于延迟期权的数字保存项目投资机会价值模型,并基于该模型探讨了延迟期权在数字保存项目建设中的作用,其中包括:①延迟期权导致数字保存项目最佳投资临界值大于传统NPV法的临界值;②延迟期权导致数字保存项目最佳投资临界值与折现率之间呈现反变关系;③延迟期权导致数字保存项目最佳投资临界值与收益波动率之间呈现正变关系;④延迟期权导致数字保存项目最优投资临界值与收益变化率之间呈现正变关系。This article analyses waiting option embedded in digital preservation project, creates digital preservation project investment opportunity value model based on waiting option, discusses functions of waiting option in setting up digital preservation project based on the model, including： ①results in the best investment critical point value more than that of traditional NPV;② waiting option waiting option resuhs in negative relationship between the best investment critical point value and discount ratio; ③ wait- ing option results in positive relationship between the best investment critical point value and income fluc- tuation ratio; ④waiting option results in positive relationship between the best investment critical point value and income change ratio.
