摘　　要：探究不同规模生猪养殖盈利能力差异及根源,对于提高生猪养殖业盈利能力具有重要意义。本文利用2000-2019年投入、产出及相应价格的省级面板数据,基于加总数量-价格分析框架,采用Färe-Primont指数,将盈利能力分解为产出-投入相对价格(TT)与TFP,探究了不同规模生猪养殖盈利能力差异及其影响因素。结果发现:2000-2007年,小规模盈利能力>中规模>大规模,主要是由于以农户家庭饲养生猪为主,较小规模的总投入价格较低;2014-2019年,盈利能力逆转,小规模盈利能力<中规模<大规模,归因于政府支持、鼓励发展规模化饲养生猪,较大规模的总投入高,但单位投入价格低且TFP更高。基于此,提出循序渐进扩大生猪养殖规模、稳定生猪养殖产出与投入价格、提高生猪养殖生产率的建议。It is of great significance for improving the profitability of pig breeding industry to compare the profitability differences of pig breeding of different scales and explore the souce of the differences.Based on the aggregate quantity-price analysis framework,this paper decomposes profitability into output-input relative price(TT)and TFP.By using provincial panel data of input,output and corresponding price from 2000 to 2018,Färe-Primont index is used to compare and analyze profitability and its influencing factors of different scale pig breeding.The results show that:In 2000-2007,the profitability of small-scale pig breeding>medium-scale>large-scale,due to Pig breeding is mainly family raise,the total input price of smaller scale is lower;In 2014-2018,the profitability was reversed,and the profitability of small-scale pig breeding<medi-um-scale<large-scale,due to the development of large-scale pig breeding,large-scale total investment is higher,but unit input price is lower and TFP is higher.Based on this,this paper puts forward some suggestions to gradually expand the scale of pig breeding,stabilize the output and input price of pig breeding,and improve the productivity of pig breeding.
