| 摘 要： | 准确评估环境政策对畜禽养殖污染排放的影响,探寻政策影响机理是科学制定畜禽养殖环境政策的重要依据。为此,本文基于2006—2018年省级面板数据,运用双重差分和中介效应模型分析了环境政策对中国畜禽养殖污染排放的影响及机制。结果表明：①自2014年以来实施的一系列环境政策有助于减少畜禽养殖污染排放;②一系列环境政策对畜禽养殖污染排放的削弱作用存在主体异质性和地区异质性,环境政策在初始污染水平较高的省份、畜牧大省以及东部省份的影响效应较为明显,在初始污染水平较低的省份、非畜牧大省以及中西部省份的影响效应不明显;③环境政策实施使得养殖总体规模下降、规模化程度提升以及养殖结构调整,进而减少畜禽养殖污染排放,而环境政策虽然能够促进农业技术进步,但难以进一步起到减少养殖污染排放的作用。据此提出要提高中国畜禽养殖环境政策的政策效率,需要进一步以差异化政策促进区域畜禽养殖污染的协调防治,挖掘规模化养殖、技术进步在污染防治中的作用,此外要高度重视生猪养殖污染防治问题。本文不仅为畜禽养殖环境政策优化调整提供定量化参考,还为推进适度规模化养殖提供一定的理论和实证依据。

| Abstract: | Accurately evaluating the impact of environmental policies on pollution emissions and exploring the policy impact mechanism are an important basis for formulating environmental policies for livestock and poultry breeding. Based on the provincial panel data from 2006 to 2018, this study analyzed the impact of environmental policies on pollution emissions from livestock and poultry breeding in China and its mechanism by applying the difference-in-differences and mediation effect methods. The results show that: (1) A series of environmental policies implemented since 2014 helped to reduce pollution emissions from livestock and poultry breeding. (2) There exist agent heterogeneity and regional heterogeneity in the reduction effects of the environmental policies on pollution emissions. The effect of environmental policies is more obvious in the provinces with higher initial pollution level, higher livestock production value, and in the eastern provinces, but not in the provinces with lower initial pollution level, lower livestock production value, and in the central and western provinces. (3) The implementation of environmental policies can reduce the overall scale of breeding, increase the degree of scaling-up production, and adjust the breeding structure, thereby reducing pollution emissions from livestock and poultry breeding. Although environmental policies can promote the progress of agricultural technology, it is difficult to further reduce the emissions of livestock and poultry breeding pollution. Therefore, in order to improve the policy efficiency, the government should further promote the coordinated prevention and control of regional livestock and poultry pollution through differentiated policies, explore the advantages of large-scale breeding and technological progress, and attach great importance to the pollution prevention and control of pig breeding. This study provides not only a quantitative reference for the optimization and adjustment of environmental policies for livestock and poultry breeding, but also certain theoretical and empirical basis for promoting moderate scale breeding. |
