摘要： 国内小麦价格支持政策在提高粮食生产的同时也产生了价格扭曲，影响了小麦产业链下游环节的福利。基于国内小麦原粮流通环节存在垄断的现实，本文分析价格支持政策向目标价格政策转换过程中对小麦加工业和消费者的福利变动产生的影响，发现价格支持政策使小麦加工业产生福利损失，原粮流通环节的垄断性越高，小麦加工业的福利损失越大；在中外价差越来越大的情况下，消费者从福利改进转变为福利损失。上述结论意味着在小麦原粮收储环节采取目标价格政策对产业链下游的加工企业和消费者都能带来福利改进。

Abstract: Domestic wheat price support policy has produced price distortions while raising grain production, which affects the welfare of the downstream link in the wheat industry chain. Based on the reality of wheat circulation monopoly in domestic, this article analyses the welfare changes of wheat processing industry and consumer in the process of conversion from price support policy to the target price policy. It shows that the price support policy makes welfare losses of the wheat processing industry, the higher degree of monopoly of grain circulation, the greater loss of wheat processing industry; in the case of increasing price difference between domestic and abroad, the consumer has changed from welfare improvement to welfare loss. The conclusion of this study means that taking the target price policy in the wheat grain storage link can bring welfare improvements to both wheat processing industry and consumer.
