在图书馆文献资源采购决策中,如何科学评价文献资源的隐性价值,制定科学的采购计划,并在有限的经费下突显馆藏资源的使用效益,成为新时期图书馆业务中面临的重要课题。文章以高校图书馆电子资源库为例,借助条件价值评估法和投资报酬率的理论,通过计算图书馆电子资源的读者愿付价格(WTP)和投资报酬率(ROI),完成图书馆电子资源服务效益的定量分析,为图书馆科学评量其馆藏资源的价值和效益提供参考。
How to scientifically appraise the hidden value of document resources, formulate a scientific procurement plan and highlight the use efficiency of the collection resources with limited funds has become an important issue in the library business in the new period. Taking the electronic library of university library as an example, this paper completes the electronic library resources by computing the WTP and ROI of library electronic resources by using the theory of conditional value assessment and return on investment. The quantitative analysis of service efficiency provides a reference for the library to scientifically evaluate the value and benefit of its collection resources.
