【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。
[Abstract]:Based on the DEA-Malmquist productivity index method, the input-output data of 15 dominant pig production areas in China from 2004 to 2012 were used to measure the variation of the raising efficiency of large-scale live pigs in China, and the difference analysis of the efficiency of pig breeding with different scales was carried out.The results show that, overall, the efficiency of large-scale pig breeding in China shows positive growth, among which, the level of small-scale breeding efficiency is the highest, the middle scale is the second, and the large scale is the lowest.Different provinces and different regions showed different breeding efficiency under different scale culture. From the time series change, the change trend of three kinds of scale aquaculture efficiency was almost the same, and the whole was "W" type.
