中文摘要：

探索生猪养殖户生态养殖模式采纳意愿的影响因素，对于促进生态养殖模式的推广、实现养猪业的可持续发展具有重要意义。基于湖南省、湖北省、河南省和天津市的调查数据，运用Ordinal Logistic模型，分析养殖户生态养殖模式的采纳意愿，探讨其采纳意愿的影响因素。结果表明，在样本生猪养殖户中，对生态养殖模式有采纳意愿的占比为37．6％，总体采纳意愿还有待提高。在生猪养殖户生态养殖模式采纳意愿的影响因素中，女性养殖户对生态养殖模式采纳意愿更高；而受教育程度、家庭务农人数、环境污染认知、生态养殖模式了解度、粪污无害化处理政策了解度以及养殖补贴政策满意度等变量，对养殖户生态养殖模式的采纳意愿具有显著的正向影响。因此，需要通过完善生猪养殖户的教育培训服务体系、提高养殖户对生态养殖模式认知和加强生猪养殖的技术和资金支持等措施来增强意愿。

Among the influencing factors, female pig farmers are more willing to adopt the ecological breeding mode. While variables such as the level of education, household size, cognition of environmental pollution, understanding of ecological breeding mode, the knowledge of harmless manure treatment policy, as well as the satisfaction to pig-breeding subsidy policy have significant positive impacts on pig farmers＇ willingness to adopt the ecological breeding mode. Therefore, it is necessary to perfect education and training service system for pig farmers, to enhance farmers＇ cognition of ecological breeding mode and to strengthen governmental support measures on technology and finance.
