成本—收益视角下的生猪养殖户死猪处理行为研究——以浙江省嘉兴市为例

Cost-benefit analysis of pig producers' disposing behaviors of dead pigs: A case study of Jiaxing,Zhejiang Province

近年来我国各地有关死猪漂浮、死猪肉流向餐桌的事件层出不穷,死猪处理成为当前较为热点的话题。基于构建养殖户成本—收益理论框架,利用在浙江省嘉兴市获得的生猪养殖户相关数据,运用多元Probit模型,分析养殖户死猪处理行为,探讨其选择行为的影响因素。结果表明,家庭劳动力数量、养殖规模、养殖模式及一些反映成本的因素会影响养殖户死猪处理方式选择;母猪和生猪死亡补贴在某种程度上可以减少养殖户损失,因此促进了养殖户申报死猪进行无害化处理;随着养殖户主要决策者的年龄、受教育水平、养殖经验的增加,养殖户随意丢弃死猪的比重会下降。最后基于分析结果提出政府部门应加大相关政策法规的宣传力度,加强监管的同时不断完善死猪补贴政策,同时要增加死猪合理处理的相关培训等政策建议,以期进一步促进我国生猪产业健康快速发展。

The events such as dead pigs floating over rivers and pork from dead pigs appearing in the market places occur in China often in recent years. Treatment of dead pigs from sickness became a hot topic. Using the data from pig producers in Jiaxing, Zhejiang Province and applying the cost-benefit framework and the multivariate Probit model, this paper conducted an empirical analysis of the factors affecting the treatment method selection of producers＇ dead pigs. Results show that the variables, such as the number of family labors, the scale of pig production operations, and production mode, have influences on the choice of producers＇ treatment of dead pigs. It can promote producers to adopt the harmless method to handle dead pigs with the subsidies of sows and pigs from the Government. With the increase of producers＇ age, education level, and production experience they will decrease their random behaviors to discard dead pigs. This paper suggests that the Government should increase the relevant propaganda of policies and regulations and establish subsidy policies to compensate producers for the dead pigs. It is significant to provide trainings for producers to help them to understand and learn the harmless treatment methods of dead pigs. The final purpose is to promote the healthy and rapid development of pig industry in China.
