摘　　要：基于Malmquist指数法,利用2006—2013年中国7个生猪非优势产区的投入产出数据,分别测度小、中、大3种饲养规模生猪非优势产区的生产效率增长与分解,并与全国平均水平进行比较。研究得出:(1)中国生猪非优势产区在小规模和大规模饲养模式下生产效率水平都要高于全国,并非非优势产区生产效率就低。(2)每种规模饲养模式下,都有生产效率最优的生猪非优势产区,但非优势产区之间,生产效率水平也存在较大差异。(3)研究期内,每一阶段生猪非优势产区在3种规模饲养模式下生产效率存在差异,而且每种规模在纵向时序上,生产效率增长速度波动性较大。Based on Malmquist index method, this paper used input-output data of live pig in 2006-2013 from seven non-dominant areas and respectively calculated growth and decomposition of live pig production efficiency under small-scale, middle-scale and big-scale, comparing with the whole nation. The main conclusions were as follows：（1） The production efficiencies of live pig in non-dominant areas under small-scale and large-scale were both higher than the whole nation, which meant that the production efficiency in non-dominant areas was not low.（2） In each breeding scale, there was one non-dominant area whose production efficiency of live pig was optimal, but among non-dominant areas, production efficiency levels were quite different.（3） In study period, the production efficiency of live pig in non-dominant areas was different in each stage of these three breeding scales, and the growth rate of production efficiency had a big volatility in each scale from the perspective of vertical timing.
