摘要
促进生猪养殖业绿色可持续发展是践行生态文明建设的具体体现。本文以长江经济带和黄河流域的面板数据为基础,运用双重差分法(DID)考察畜牧环保政策对两个区域生猪产能的影响。研究结果表明:畜牧环保政策对长江经济带和黄河流域生猪产能的影响具有明显区域差异性。进一步通过构建中介效应模型检验生猪产值、机械化水平对区域的生猪产能的影响,发现在畜牧环保政策的影响下,长江经济带上各省(市、区)对生猪产能影响效果的中介因素是产值,而黄河流域各省对生猪产能影响效果的中介因素是机械化水平。据此,提出发展适度标准化规模经营、探索绿色可持续的生猪产业发展新模式、推进生猪产供保障能力与环境协同发展等建议。
Promoting green and sustainable development of hog breeding industry is the concrete embodiment of practicing ecological civilization construction.Based on panel data from the Yangtze River Economic Belt and the Yellow River Basin,this paper uses the differences-in-differences(DID) to investigate the impact of animal husbandry and environmental protection policies on hog productivity in the two regions.The results show that the impact of livestock environmental protection policies on hog productivity in the Yangtze River Economic Belt and the Yellow River basin has obvious regional differences.Further,the mediating effect model was constructed to test the influence of hog output value and mechanization level on regional hog productivity,found in animal husbandry under the influence of environmental policy,the Yangtze river economy belt provinces(cities,districts) of hog production effect of intermediary factor is output,and the Yellow River basin effects on hog production provinces of intermediary factor is the level of mechanization.Accordingly,some suggestions were put forward,such as developing moderate standardized scale operation,exploring a new green and sustainable development model of hog industry,and promoting the coordinated development of hog production,supply and security capacity and environment.
