指出从规模经济、文献信息的公共产品属性及其外部性三个角度来讲,电子文献共享都是一种更有效率的选择。分析在特定定价模式下的两种可能的共享模式,提出文献信息资源的集中许可与共享模式,以文献用户的需求相似度为共享联盟的形成基础,以提高科研人员的文献可及性为目标,在理论上可以提高现有文献信息资源的获取效率,进而提高研究者的研发效率。 It points out that electronic document sharing is a more efficient choice from the perspectives of economies of scale, public goods attributes of literature and information and its externalities. This paper analyzes two possible modes of sharing in a particular pricing model and puts forward the centralized licensing and sharing mode of the literature information resources. It takes the similarity of the needs of the literature users as the basis for forming the sharing alliance and aiming at improving the document accessibility of the researchers , In theory, can improve the efficiency of obtaining the existing literature information resources, thereby enhancing the researchers’ research and development efficiency.
