中文摘要：

为评估疫区养殖户的经济损失,分析补偿政策对养殖户损失的支持强度,制定合理的疫情补偿标准提供理论和实证依据,利用宁夏中卫禽流感疫区的微观调研数据,建立蛋鸡养殖户经济损失评价模型,进而评价疫区散养户和规模养殖户的经济损失及其补偿政策支持强度。结果表明：禽流感疫情给疫区蛋鸡养殖户造成的间接经济损失大于直接经济损失;疫区蛋鸡养殖户遭受的经济损失因蛋鸡月龄而异,5个月的蛋鸡给养殖户带来的经济损失最大;疫区蛋鸡养殖户遭受的经济损失因其饲养方式而异,规模养殖户遭受的经济损失相对较大;国家和宁夏疫情补偿标准仅能弥补疫区蛋鸡散养户和规模养殖户经济损失的24.64%、20.94%和26.29%、22.02%,补偿强度不足,补偿标准的满意度较低。政府一方面要完善蛋鸡养殖户疫情损失构成,提高疫情补偿额度;另一方面要考虑蛋鸡月龄和养殖户的饲养方式,制定差异化的补偿标准。

英文摘要：

To provide theoretical and empirical basis to formulate reasonable compensation standard for government,a model of farmers＇ economic losses is built toevaluate the free-range and scale farmers＇ economic losses and the compensating degree of policy under the outbreak of avian influenza based on the survey data of avian-infected area,Zhongwei in Ningxia.The outbreak of avian influenza causes severe economic losses to farmers,and the indirect economic losses are larger than the direct losses;the farmers＇ economic losses in avian-infected area are variant due to the age of layer chicken,and specifically farmers raising 5 months layer chicken suffer the most serious economic losses;the economic losses are different among farmers because of differing in the way to feed layer chicken,and concretely the scale farmers＇ economic losses are larger than the free-range farmers＇;compensation policy in our country can make up 24.64% and 20.94% economic losses of scale farmers＇ and free-range farmers＇ respectively.Meanwhile compensation policy in Ningxia can compensate 26.29% and 22.02% of their economic losses respectively,indicating the satisfaction of compensation policy is low.When making compensation policies for avian influenza,the government should consider the components caused farmers＇ economic losses,which is raising the compensation standard on one hand,setting differential compensation standards according to the age of layer chicken and the way to feed layer chicken on the other hand.
