摘 要：
基于DEA-Malmquist生产率指数法,利用2004—2012年中国15个生猪优势产区的投入产出数据,测度了中国规模化生猪养殖效率的变动情况,并对不同规模的生猪养殖效率进行差异化分析。研究结果表明,总体来看,中国规模化生猪养殖效率均呈现正向增长,其中,小规模养殖效率水平最高,中规模次之,大规模最低;从省际和区域层面看,不同省份不同区域在不同规模养殖下呈现出不同的养殖效率;从时序变化看,研究期内3种规模的养殖效率变化趋势几乎一致,整体呈"W"型。

摘 要：
Based on Malmquist index method,the input-output data of 15 major live pig-producing regions from 2004 to 2012 in China were adopted to measure the breeding efficiency change of China's scale pig and analyze the regional diversities under different breeding scales. It was shown that all the breeding scales exhibited a positive growth in breeding efficiency from the perspective of the nationwide average Malmquist index. The small-scale breeding showed the highest breeding efficiency,while the large-scale breeding exhibited the lowest efficiency. On the provincial and regional level,even in the same scale breeding,breeding efficiency varied among different regions in different provinces. According to the sequential change from 2004 to 2012,the changes of breeding efficiency in three breeding scales were almost the same as a "W"shape.
