中国生猪养殖从农户散养向规模化养殖迅速转变的同时,规模化养殖所带来的粪便污染越来越引起重视。本文通过对7省规模化生猪养殖场的实地调查数据,使用条件价值评估法分析规模化生猪养殖场对其污染防治的支付意愿。结果表明,不管是愿意支付的生猪养殖场还是不愿意支付的生猪养殖场,均认为生猪养殖污染防治带来的社会效益>生态环境效益>经济效益。在愿意支付的受访生猪养殖场对生猪养殖污染防治带来的生态价值平均支付意愿是总收入的10.64%,对社会价值平均支付意愿是总收入的8.62%,对经济价值的平均支付意愿是10.11%。最后,提出了相应的政策建议。

In this paper, through the field survey data and condition of use value assessment of large-scale pig farms in seven provinces, the willingness to pay for the prevention and control of pollution by large-scale pig farms is analyzed. The results showed that regardless of whether they are willing to pay the pig farms or unwilling to pay the pig farms are considered pig breeding pollution prevention and control of social benefits> ecological and environmental benefits> economic benefits. The average willingness to pay for the ecological value of pig breeding pollution prevention and control of the surveyed pig farms is 10.64% of the total income, the average willingness to pay for social values is 8.62% of the total income, and the average willingness to pay for economic values is 10.11%.
