【Abstract】 The concept of stochastic elasiticity is introduced and its correlative properties are discussed. Further, the stochastic demand elasticity is given. The change and influence of demand is analysed by using the stochastic demand elasticity when the receipts of consumer groups are random variable. The elastic distribution of demand is given when the receipts obey a certain distribution.更多还原
