【摘要】Based on the DEA-Malmquist index method,by using the panel data of provinces in milk production over the year between 2004 and 2011,this paper analyzes the relationship between milk production total factor productivity(TFP) and dairy farm scales (backyard,small-scale,medium-scale and large-scale dairy farms).Results show that,the TFP of backyard and small-scale dairy farms is lower than that of the medium-scale and large-scale dairy farms from the national level and as the time goes by,advantages of mass-breeding become increasingly prominent.But the relationship varies in the province level:TFP rises as the scale increases in Inner Mongolia and Jilin Province,on the contrary,TFP decreases with the scale goes up in Shandong and Henan Province.Besides,technological progress is the main driving force for milk production TFP during the period of 2004-2011,both in the country level and for provinces.%采用DEA-Malmquist生产率指数法,运用2004-2011年我国奶牛养殖的省级面板数据,本文分别从全国层面和省份层面对比分析了奶牛养殖模式(散养、小规模、中规模和大规模)与原料奶生产全要素生产率(TFP)的关系.研究结果显示,从全国层面看,散养和小规模的TFP小于中规模和
