| 摘 要： | 运用DEA方法,测算了我国散养、小规模、中规模和大规模四种生猪饲养模式的生产效率。结果表明：2002—2010年生猪生产效率的提高主要依靠要素投入规模的扩大,技术效率的贡献次之;不同省份间不同养殖规模下的生猪生产效率及最优规模存在差异。研究认为各地要因地制宜地选择适度的养殖规模。

| Abstract: | Using DEA method,this paper has calculated the production efficiency of scatter-feed,small scale,middle scale and large scale in China between the periods of 2002 to 2010.The results show that:production efficiency enhance in China from 2002 to 2010 mainly rely on the expansion of the inputs scale,the contribution of technological efficiency take the second place.Production efficiency and the optimal breeding scale of different scales of live pig between different regions and provinces and cities exists difference.In the process of live pig’s production development,various regions should adjust measures to local conditions to choose the moderate breeding scale. |
