中文摘要:
      以标准化养殖场建设及畜禽粪污资源化利用为研究背景,利用江苏、河北、山东三省的401个蛋鸡养殖场的调研资料,采用内生转换模型和空间自相关模型实证分析了标准化养殖场建设对养殖场环境投资的影响效用大小,并探究了标准化养殖场对周边养殖场环境投资是否存在示范效应。结果显示:标准化养殖场能显著提高养殖场的环境投资;标准化养殖场环境投资的影响因素与非标准化养殖场有显著区别,标准化养殖场的环境认知和所受环境监管约束要高于非标准化养殖场;标准化养殖场对周围养殖场环境投资的示范效应高于非标准化养殖场。由此,政府应继续推进标准化养殖场的创建工作,提高标准化养殖场的环境准入门槛,提升标准化养殖场的环境示范效应;此外,政府还应调动非标准化养殖场申报的积极性,加强对非标准化养殖场的环境监管。
英文摘要:
      Based on development of standardized farms and resource utilization of poultry waste,this research analyzed the impacts of standardized farms on farmers’ environment investment by using endogenous switching regression model and spatial autoregression model,the data of which came from 401 laying hens farm in Jiangsu,Hebei and Shandong provinces.Meanwhile,this research also verified whether the standardized farms posed a demonstration effect on farms’ surroundings.Results showed that:(1) Standardized farms could significantly improve the farmers’ environmental investment; (2) Influence factors in farm’s environmental investment of standardized farms and non standardized farms were extremely different and farmers’ environmental awareness and environmental supervision in standardized farms were stronger than those in non-standardized farms; (3) The effect of standardized farms on the surrounding farmers’ environmental investment was higher than non standardized farms as well.Therefore,government should promote the establishment of standardized farms continuously,improve the environmental standardized farm’s access simultaneously and meanwhile enhance the environmental demonstration effect of standardized farms.In addition,government should also encourage non-standardized farms to declare standardization and strengthen the environmental supervision on non-standardized farms.
