为了解不同规模养殖户对畜禽污染治理政策的接受意愿,基于全国5省754个生猪养殖户的实地调查数据,运用选择试验方法实证检验了不同规模养殖户对技术培训、排污费、技术标准、沼气补贴和粪肥交易市场5项畜禽污染治理政策的接受意愿。研究结果表明,不同规模养殖户对畜禽污染治理政策的接受意愿具有异质性。小规模养殖户对沼气补贴政策的接受意愿最高,其次为全面技术培训和一般技术培训政策,对技术标准政策的接受意愿最低;中规模养殖户对沼气补贴政策的接受意愿最高,其次为粪肥交易市场和全面技术培训政策,对排污费政策的接受意愿最低;大规模养殖户对粪肥交易市场政策的接受意愿最高,其次为沼气补贴和技术标准政策,对一般技术培训政策的接受意愿最低。畜禽污染治理政策对不同规模养殖户的激励程度不同。中规模养殖户在各项政策下畜禽污染处理率的提高比例均较高,小规模养殖户在各项政策下畜禽污染处理率的提高比例均较低。
In order to understand the willingness of farmers of different sizes to accept pollution control policies for livestock and poultry, based on the field survey data of 754 pig farmers in 5 provinces in China, this paper empirically tests the impacts of technical training, sewage charges, technical standards , Biogas subsidies and manure trading market 5 animal husbandry and pollution control policies of willingness to accept. The results show that farmers of different sizes have a heterogeneous willingness to accept pollution control policies. Small-scale farmers have the highest willingness to accept biogas subsidy policies, followed by comprehensive technical training and general technical training policies, with the lowest willingness to accept technical-standard policies; medium-scale farmers have the highest willingness to accept biogas subsidy policies, followed by manure trading Market and comprehensive technical training policies, with the lowest willingness to accept sewage charges; large-scale farmers’ willingness to accept market-based policies in manure trading, followed by biogas subsidies and technical standards, and the lowest willingness to accept general technical training policies. Livestock and poultry pollution control policies for farmers of different sizes have different levels of motivation. Medium-scale farmers in all policies to improve the rate of livestock and poultry pollution were higher, small-scale farmers in all policies to improve the rate of livestock and poultry pollution rates are lower.
