摘　　要：通过建立供给需求方程分别测度小麦的需求价格弹性、供给价格弹性和收入弹性,在此基础上,对农户的长短期消费者福利效应和生产者福利效应进行有效测度并比较最低收购价政策实施之前与实施之后所存在的差异。结果表明:1作为主粮之一,小麦供给和需求均缺乏弹性,其供给价格弹性、需求价格弹性和收入弹性的值分别为0.461 5、-0.387 2和-0.173 1。2农户福利明显受到了小麦最低收购价政策的影响,该政策的实施有效促进了农户福利的增加;具体而言,它带给农户的福利变化以生产者福利为主,且其福利变化的长期效应与短期效应基本一致。基于研究结论有针对性地提出优化小麦最低收购价政策设计、构建小麦最低收购价价差体系、提高小麦最低收购价政策的执行效果、逐步改善小麦最低收购价政策的配套措施等对策建议。The supply and demand equations of wheat were established to measure its price elasticity of supply,price elasticity of demand and income elasticity.The welfare of consumers and producers for short and long term were calculated.And the welfare differences before and after the implementation of the flour price policy were illustrated.The results showed there was a lack of elasticity in wheat supply and demand,which was demonstrated by 0.461 5,-0.387 2and-0.173 1,respectively in supply price elasticity,demand price elasticity and income elasticity.Farmers' welfare was evidently affected by the price policy whose implementation effectively brought welfare increase.Specifically,the increase was mainly concerned with producers welfare.The long-term effect was basically the same with that in short term.Finally,some suggestions were pertinently put forward,such as to optimize the minimum purchase price policy of wheat,to construct the system of minimum purchase price of wheat,to improve the implementation effect of the minimum purchase price policy,and to gradually improve the matching measures of the minimum purchase price policy.
