【摘要】 粮食价格波动牵涉众多主体的切身利益,价格太低导致"谷贱伤农",价格太高导致"米贵伤民"的现象。从保护消费者和生产者利益角度来说,政府可以采取价格稳定政策,也可以采取目标价格补贴政策。政府该如何做才能增加社会福利?本文研究认为,在不考虑制度成本条件下,粮食价格稳定政策能够实现社会福利增加;但是粮食价格调控体系存在的巨额制度成本将极大改变粮食价格稳定政策的社会福利效应,甚至会导致社会福利的恶化、财政负担的加剧,只有有效降低制度成本才能实现社会福利增加;目标价格补贴政策能够节省大量的粮食储备及调控成本,较好弥补价格波动对生产者与消费者福利的影响,但是目标价格的厘定是否合适和价格补贴效率对社会福利水平具有重要影响。更多还原

【Abstract】 Food price volatility has a very important effect on many people. When the price is too low,"low price of grain hurts farmers". When the price is too high,"high price of rice hurts consumers". From the perspective of the interests of consumers and producers,the Government can take the price stability policy or the target price subsidy policy. Which should the government do to increase social welfare?The results show: if we don’t consider the factor of the system cost,food price stabilization policies can increase the social welfare. There is a huge system costs which will greatly change the effects of social welfare,and even lead deterioration of social welfare,increasing financial burden. The government can save a lot of reserves and regulation costs when they take the target price subsidy policy,and can compensate for the impact of price fluctuations on the welfare of producers and consumers. However,the efficiency of price subsidies has a significant impact on the social welfare level.更多还原
