摘　　要：为了研究超市商品“薄利多销”的有效性,以大数据分析为手段,建立了销售额与折扣率的双对数回归模型,发现销售额关于折扣率的弹性2.0396>1,是富有弹性的,说明加大打折力度会显著增加销售额,“薄利多销”是有效的;又建立了利润率与折扣率的线性回归模型,发现利润率的边际-0.7531<0,说明利润率随折扣率的增加而减少,“打折让利”是有效的;最后给出了最优折扣率的确定方法,为超市商品制定“薄利多销”策略提供决策参考。In order to study the effectiveness of retailer’s“small profits but quick returns”,a double logarithm regression model of sales volume and discount rate is established by means of big data analysis.It is found that the elasticity of sales and discount rate is2.0396>1,which is elastic.It shows that increasing discount will significantly increase sales volume,and“small profits but quick returns”is effective.In addition,a linear regression model of profit rate and discount rate is established,it is found that the marginal profit rate is-0.7531<0,which indicates that profit rate decreases with the increase of discount rate,and“discount”is effective.Finally,this paper gives the method of determining the optimal discount rate,which provides a decision reference for retailers to make the strategy of“small profits but quick returns”.
