摘要

In,order to analyze the power ofbommodity diversification to counter the effects produced, the researcher designed a model, in this model, a monopoly s upplier through a chain of retailers and nonchain retailers sell a range of different products. And that in equilibrium, the power to compete with chain retailers, the increase was made will reduce the amount of goods and commodity diversification to reduce the retail price will be accompanied by a decline. Thus, there is concern fhe theoretical analysis of price Chaages ＇can not fully explain how it affects the power to compete consumer welfare.%为了分析抗衡力量对商品多样化所产生的效应，我们设计了一个模型，在这个模型中，一个垄断的供应商通过连锁零售商和非连锁零售商来销售一系列不同的商品，结采表明在均衡状态下，随着连锁零售商抗衡力量的增加，被制造的商品量将会减少。并且商品多样化的减少将伴随着零售价挎的下降。因此，就存在的理论分析所关注的价格的变代并不能完全说明抗衡力量是如何影响消费者福利的。
