一类典型的非线性需求条件下的变折扣率研究

Study on Unfixed Discount Rate Under the Condition of a Sort of Typical Nonlinear Demands

在一类典型的非线性需求条件下，分别研究了垄断厂商在二段定价、三段定价以及n段定价情形下最优变折扣率的确定问题，并且给出了垄断厂商在实施变折扣率时收益最大化的条件，进一步地给出了垄断厂商实施段定价时各需求区间最优变折扣率的表达式。

Under the condition of a sort of typical nonlinear demands,this paper mostly investigates the unfixed discount rate optimization of monopoly manufacturers when they make second-pricing,third-pricing and n pricing. It gives the condition of the revenue maximization when monopoly manufacturers make the unfixed discount rate. Furthermore,the formulate of the unfixed discount rate optimization is set when monopolymanufacturers make th-pricing.
