图书馆与出版商利润关系的经济模型

On the Economic Model of Library and Publishing House Profits

一般认为 ,图书馆的出现会减少购买信息产品的消费者人数 ,从而减少出版商的利润。但从理论模型分析推导来看 ,图书馆的存在会使信息出版商的利润增加 。

Generally speaking, libraries will reduce the number of consumers, which accordingly reduce the demand of the information products and profit of the publishers. On the contrary, libraries can increase the profit of the publishers from theoretical mode. Only when the increase of libraries reaches a certain limit, can the profits of the publishing house be reduced.
