点弹性
点弹性点弹性分为需求点弹性和供给点弹性，是指商品需求曲线或供给曲线上某一点的弹性，它等于商品需求量或供给量的无穷小的相对变化与该商品价格的无穷小的相对变化。用数学公式表示: dq__q_dq_P7d一一万二一一石二’二了 “尸“尸甘 Pq表示需求量;P表示价格;和表示需求点弹性。 dq或:。一圣一空，粤~·“dP dPq Pq表示供给量，户表示价格.从表示供给点弹性。根据点弹性公式.能够计算出商品需求量或供给量随商品价格变化的程度。点弹性的值一方面取决于需求曲线或供给曲线的斜率，另一方面则取决于价格与数量的比值。在线性的需求曲线或供给曲线上，斜率不变，但需求曲线或供给曲线上任何一点的点弹性因价格与数量的比值不同而不同，点的位置越高，弹性越大;反之，点的位置越低，则弹性越小。
