摘要
[目的]蛋鸡养殖场规模化养殖与生态环境保护协调发展问题是蛋鸡养殖业可持续发展过程中面临的关键性问题,测度我国大、中、小3种规模下不同省份蛋鸡养殖场的环境全要素生产率,并从时间、地区两个维度对蛋鸡养殖场的环境全要素生产率进行比较。[方法]利用2004—2016年不同养殖规模蛋鸡养殖场的投入和产出数据,文章基于SBM函数的Malmquist-Luengerber(ML)指数方法,对蛋鸡养殖场环境全要素生产率进行分解,将其分解为技术进步指数、效率改进指数。[结果](1)蛋鸡养殖场环境全要素生产率整体呈现下降趋势,同时与蛋鸡养殖规模呈反比,蛋鸡养殖场规模越大,蛋鸡养殖环境生产率越小。(2)蛋鸡养殖场效率存在效率改善,但养殖技术进步率相对较低,尤其是对小规模养殖场而言,改善空间更明显;(3)蛋鸡养殖环境全要素生产率区域差异较为明显,整体来看,蛋鸡养殖主产区环境全要素生产率高于非主产区。[结论]加强蛋鸡产业科技创新水平以及公共服务设施的投入,提高养殖户的废弃物无害化处理能力,推行蛋鸡养殖的规模化和标准化发展,进一步改善养殖效率,以促进蛋鸡养殖规模化和生态环境保护协调发展。
It is a key issue that the problem of coordinated development of large-scale breeding and ecological environment protection in laying hens in the sustainable development.According to different breeding scales,the breeding scales can be divided into large,medium and small scales.In this paper,it measures the laying of laying hens in different provinces in China.And the environmental total factor productivity of the field is compared from the time and regional dimensions.Based on the input and output data of laying farms of different breeding scales from 2004 to 2016,the Malmquist-Luengerber(ML)index method of SBM function was used to decompose the total factor productivity of laying hens into a technological progress index and an efficiency improvement index.The results showed that(1)The overall factor productivity of laying hens showed a downward trend,and it was inversely proportional to the scale of laying hens.The larger the laying hens were,the smaller the productivity of laying hens was.(2)The efficiency of laying hens had improved efficiency,but the rate of technological progress was relatively low,especially for small-scale farms,the space for improvement was more obvious;(3)The regional difference in total factor productivity of laying hens was more obvious.Overall,the total factor productivity of the main production areas of laying hens was higher than that of non-main producing areas.In summary,it should strengthen the level of scientific and technological innovation in the laying hen industry,improve the harmless disposal capacity of farmers′wastes,carry out the large-scale and standardized development of laying hen breeding,so as to improve the breeding efficiency and promote the coordinated development of large-scale laying hen breeding and ecological environment protection.
