摘　　要：文章基于2004—2018年生猪养殖的省级宏观数据,采用随机前沿生产函数测算了小规模、中规模、大规模生猪养殖TFP的变化情况,并对TFP增长率进行了分解。结果显示:小规模、中规模、大规模生猪养殖TFP年均增长速度分别为2.45%、4.41%、3.76%。配置效率变化和技术变化会同时促进小规模、中规模、大规模生猪养殖TFP增长,其中,配置效率变化是推动生猪养殖TFP增长的主要因素。技术效率变化会促进中小规模生猪养殖TFP增长,而规模效率变化会促进中大规模生猪养殖TFP增长。随着时间推移,配置效率变化曲线和TFP增长率曲线表现出高度的吻合性。Based on the provincial macro data of pig breeding from 2004 to 2018,this paper uses the stochastic frontier production function to measure the change of total factor productivity(TFP)in small-scale,medium-scale and large-scale pig breeding,and then decomposes the growth rate of TFP.The results are shown as below:The average annual growth rate of TFP in small-scale,medium-scale and large-scale pig breeding is 2.45%,4.41% and 3.76%,respectively.The change of allocation efficiency and technology will promote the TFP growth of small-scale,medium-scale and large-scale pig breeding at the same time,of which the change of allocation efficiency is the main factor to promote the TFP growth of pig breeding.The change of technical efficiency will promote the TFP growth in medium-scale and small-scale pig breeding,while the change of scale efficiency will promote the TFP growth in medium-scale and large-scale pig breeding.As time goes on,the allocation efficiency curve and TFP growth rate curve show a high degree of similarity.
