摘　　要：类似于微观经济学中的“交叉价格弹性”,提出“需求交叉弹性”概念,通过两种需求量具有一定刚性的生活必需品的需求量变化之间的关系,计算需求交叉弹性,可以判别商品之间的竞争关系或互补关系,测量一种商品数量变动引起相关商品数量变动的强度.结合小型居民超市特点,采用其历史数据,对有关商品的需求量进行预测,为小型超市的补货计划提供参考.示例表明,利用这种方法进行补货,可证是有效的.Similar to the concept of"cross-price elasticity of demand"in microeconomics,this paper proposes the concept of"cross-elasticity of demand",which can reflects the complementary or alternative relationships between goods that have stable volume of demand.It can also be used to measure the strength of a change in the number of one kind of goods associated with a change in the number of another kind of goods.Based on the characteristics of mini marts,this paper forecasts the demand of relevant commodities by using its historical data,and provides reference for the replenishment plan of mini marts.Examples show that replenishment using this method is proven to be effective.
