【摘要】：本文在利用相关资料数据计算得到生猪规模养殖的投入、产出的基础上,构建SE-DEA模型,对中国17个生猪主产区2004—2014年规模养殖的环境效率进行测算,比较各主产区不同规模养殖的环境效率,分析不同规模下各区域环境效率的时序变化特征。结果表明:整体上生猪规模养殖环境效率呈现出明显的区域和规模差异,中部和西南优势区比东北及沿海优势区的养殖环境效率更高,大规模养殖环境效率最高,小规模次之,中规模最低;沿海优势区较为适合发展中小规模养殖,东北优势区较为适合发展大规模养殖,中部地区较为适合发展中小规模养殖,西南优势区较为适合发展小规模及大规模养殖。
[Abstract]:On the basis of calculating the input and output of pig scale breeding by using the relevant data, this paper constructs SE-DEA model to measure the environmental efficiency of large-scale breeding in 17 major pig producing areas in China from 2004 to 2014. The environmental efficiency of different scale aquaculture in main producing areas was compared, and the temporal variation characteristics of environmental efficiency in different scale were analyzed. The results showed that there were obvious regional and scale differences in environmental efficiency of pig scale breeding on the whole. The environmental efficiency of culture is higher in the central and southwest dominant areas than in the northeast and coastal areas. The environmental efficiency of large-scale aquaculture is the highest, followed by small scale, and the middle scale is the lowest. The coastal dominant areas are more suitable for developing medium and small scale aquaculture. The northeast dominant region is more suitable for developing large-scale aquaculture, the central region is more suitable for developing medium and small scale aquaculture, and the southwest dominant area is more suitable for developing small-scale and large-scale aquaculture.
