分析图书馆拥有模式和存取模式的投入产出情况,试图从经济学的角度为不同模式的选择提供一种思考的依据。但是,图书馆的投入产出不能仅仅以资金或资产的增加与否来衡量,从投入产出看,图书馆的投入是看得见的,而产出往往是看不见的。图书馆必须根据自身的特点、读者的特点去作出选择。 This paper analyzes the input and output of library ownership model and access model and attempts to provide a basis for thinking about the choice of different models from an economic point of view. However, the input and output of libraries can not be measured solely by the increase of funds or assets. From the perspective of input-output, library inputs are visible and outputs are often invisible. Libraries must make their own choices based on their own characteristics and reader characteristics.
