运用弹性分析理论剖析“薄利多销”

Analyzing"Small Profits but High Sales"based on the Elastic Analysis Theory

利用弹性函数及需求函数在经济中说明总收益的变化情况,讨论某类商品可用薄利多销的原因,某类商品不可用薄利多销的原因。在需求弹性中,反比例的需求函数Q=K/P(K为常数),两点之间的平均弹性有■(P_(0),P_(1))×■(P_(1),P_(0))规律。当需求对价格的弹性等于1时,需求的变动幅度等于价格的变动幅度,此时收益取得最大值。让学生理解经济数学在经济分析中的重要性,鼓励学生掌握经济数学的基本概念及灵活应用。

Utilizing the elastic functions and the demand functions to demonstrate the changes in total revenue in the economy,the reasons why certain commodities can be sold on the principle of small profits but high sales,while others cannot be sold have been discussed.In demand elasticity,the inverse proportional demand function is■(K being a constant),and the average elasticity between two points for the demand function has the following rule:■When the elasticity for demand to price is equal to 1,the variation in demand is equal to the one in price.At this moment.the revenue reaches the maximum value.It aims to teach students the significance of economic mathematics in economic analysis,and to encourage them to master the basic concepts and the flexible applications of economic mathematics.
