摘  要:纯随机NBD-Dirichlet模型可以用来研究消费者的零售店选择行为(商店选择与购买频次),但是由于模型中没有协变量,所以无法对消费者的商店选择行为进行解释。本论文对纯随机模型进行了拓展,引入了解释变量,并应用拓展的模型对北京的消费者超市选择行为进行了实证研究。其中的主要发现为:(1)市场渗透率是超市经营的关键指标;(2)促销没有对消费者超市选择产生影响,但是它能够使顾客更多地惠顾超市;(3)家庭收入对消费者选择超市以及惠顾频次的多少均有显著的影响;(4)单次购买金额对消费者选择超市没有显著影响,但是它对消费者惠顾频次有负向的影响;(5)超市之间的价格差异较小,因此价格对消费者购物频次没有影响;(6)产品的齐全性对消费者超市选择有巨大的影响。The pure stochastic NBD-Dirichlet model can be applied to study consumers' retail store choice behavior (store choice and shopping frequency). However, due to lack of covariate variables in the model, it cannot explain consumers' store choice behavior. This article extends the pure stochastic model by incorporating explanatory variables, and applies the extended model to empirically study consumers' supermarket choice behavior in Beijing. The major findings include: (1) Market penetration is the critical indicator of supermarket performance; (2) Promotion has no effect on consumers' supermarket choice, but it has positive significant effect on consumers' shopping frequency;(3) Household income has significant effects on both supermarket choice and shopping frequency; (4) Amount of expenditure per store trip has no effect on store choice, but it has negative significant effect on shopping frequency; (5) There is little price variation among supermarkets so price has no effect on consumers' shopping frequency; and (6) Product assortment has tremendous impact on consumers' supermarket choice.
