摘要
探究我国各区域规模生猪养殖的环境效率,对指导生猪产业绿色发展具有重要的意义。文章基于2010—2020年我国24个生猪主产省的面板数据,运用SE-SBM模型对我国规模生猪养殖进行环境效率测算。结果显示:规模生猪养殖的环境效率与养殖规模成正比;中、大规模生猪养殖的环境效率在波动中提升,小规模持续稳定在较低水平;东、中部地区规模生猪养殖的发展要优于西部地区;山东省、河北省和重庆市的规模生猪养殖对其他省市具有一定的示范作用;仔畜、疫病防控投入冗余以及化学需氧量和全氮排放过量是规模生猪养殖产生效率损失的主要原因。推动生猪规模化养殖,需适当地引导生猪养殖适度规模发展,着力减少资源耗能和污染排放。
Exploring the environmental efficiency of large-scale pig breeding in various regions in China is of great significance to guide the green development of the pig industry.Based on the panel data of 24 major pig-producing provinces in China in 2010—2020,this paper used the SE-SBM model to measure the environmental efficiency of large-scale pig breeding in China.The results showed that’the environmental efficiency of large-scale pig breeding was directly proportional to the breeding scale.The environmental efficiency of medium-scale and large-scale pig breeding had improved in fluctuations,and small-scale pig farming had continued to stabilize at a low level.The development of large-scale pig breeding in the eastern and central regions was better than that in the western region;Large-scale pig breeding in Shandong Province,Hebei Province and Chongqing City had a certain exemplary role for other provinces and cities;Redundancy of investment in piglets,disease prevention and control,and excessive chemical oxygen demand and total nitrogen emissions were the main reasons for the loss of efficiency in large-scale pig farming.In order to improve the environmental efficiency of pig breeding in China,it was necessary to appropriately guide the moderate scale development of pig breeding and focus on reducing resource consumption and pollution emissions.
