概述图书馆电子资源的采购现状,分析高校图书馆电子资源的采购比例,利用经济学中消费者均衡理论的预算线、无差异曲线及效用最大化等理论知识,认为图书馆电子资源采购经费的比例分配可利用消费者均衡理论来实现效用最大化,提出构建高校图书馆电子资源采购经费的最优比例模型。 This paper summarizes the status quo of procurement of library electronic resources, analyzes the proportion of procurement of electronic resources in university libraries, makes use of the theorem of budget line, indifference curve and utility maximization of consumer equilibrium theory in economics, Proportion distribution can use the theory of consumer equilibrium to maximize utility, and propose an optimal proportional model for the construction of university library electronic resources procurement.
