摘　　要：运用SBM方向性距离函数和Luenberger生产率指标对2004—2013年中国生猪养殖业生产效率和全要素生产率进行测算,并在此基础上就其影响因素做进一步研究。结果发现:中国生猪养殖业生产效率较高的省份多数集中在西部地区;青粗饲料投入无效率、劳动力投入无效率、其他物质费用投入无效率以及仔畜重量无效率皆是中国生猪养殖业生产无效率的主要来源;2004—2013年中国生猪养殖业全要素生产率的增长率为-12.98%,这主要是受到规模效率和技术进步率逐渐减少的制约;生猪精饲料费在总饲料费中的比例以及各地区经济发展水平对生猪养殖业生产效率和全要素生产率具有显著的正向作用。This paper applies SBM directional distance function and Luenberger productivity indicator to measure Chi-na, s pig breeding productive efficiency and total factor productivity （ TFP） from 2004 to 2013 with an analysis of its influence factors. The major conclusions are as follows ： higher efficiency of pig production provinces were mostly con-centrated in western regions, overuse of roughage and labor input, unreasonable other material costs input as well as overweight of newborn animal are the main sources of pig production inefficiency in China. The growth of pig breeding TFP in China is - 12. 98% from 2004 to 2013, which is mainly restricted by the gradually decreased scale efficiency and technical progress rate. The cost proportion of concentrate fee in pig breeding and different level of regional eco-nomic development have positive and significant effects on China,s pig breeding productive efficiency and TFP.
