需求价格弹性在现实中的应用研究

Study on application of price elasticity of demand in reality

从企业利润最大化的视角出发,利用需求价格弹性这一潜在的经济规律,通过构建数学统计模型的方法以明确需求价格弹性与企业利润之间的内在联系,并采用现实中2003年北京东城区、宣武区与西城区等十区的房价与销售量数据作为实例,采用线性回归的方法拟合得出北京住宅房的价格需求弹性是大于1的,即富有弹性,按照利润与需求价格弹性的关系,我们得出当P平均=EV-0E1时,厂商获得最大利润,即验证了分析结论。

This paper starts from the view of enterprise＇ profit maximization, using the potential economic laws of price elasticity of demand to clarify the intrinsic link between the price elasticity of demand and enterprise＇ profits by constructing mathematical statistical model. In addition, this paper takes the real case of housing price and sales in Beijing in the year of 2003 as an example, including Dongcheng district, Xuanwu district and Xi- cheng District and other seven districts, using the linear regression method fitting that the Beijing residential price elasticity of demand is greater than 1, that is flexible. According to the relationship between profits and the price elasticity of demand, we have conclude that when P平均=V0E/E-1,the enterprises get the maximizedprofits, which verify our conclusions.
