摘　　要：本文基于资本密集型养殖的视角,梳理了养殖资本化对生猪价格波动的作用机理,并运用2002~2014年中国30个省份的面板数据,测算中国生猪养殖的资本化水平,综合考察养殖资本化对生猪价格波动的稳定效应。研究结果表明:养殖资本化对生猪价格具有显著的稳定作用。在研究样本期间,养殖资本化对生猪价格的稳定效应为0.330,即养殖资本化率每提高1个单位,将推动生猪价格波动率下降0.330个单位。此外,养殖资本化对生猪价格的稳定效应呈现明显的区域差异,西部地区的稳定效应最大,东部地区的稳定效应次之,中部地区的稳定效应在模型中不显著。中规模资本养殖和小规模资本养殖是平抑价格波动的主要力量,大规模资本养殖的稳定作用不明显。This article analyzes the influencing mechanism of farming capitalization on hog price fluctuation from the perspective of capital intensive farming,and uses panel data from 30 provinces in China from 2002 to 2014 to calculate the capitalization level of hog farming in China.The study examines the stabilization effect of farming capitalization on hog price fluctuation in a comprehensive way.The results show that farming capitalization has a significant stabilization effect on hog prices.During the time period of the sample,the stabilization effect of farming capitalization on hog prices was 0.330.That means one-unit increase in the level of farming capitalization would induce hog prices fluctuation by 0.330 units.Besides,significant regional differences exist regarding the stabilization effect of farming capitalization on hog prices.The stabilization effect in the western region is the largest,followed by the eastern region,being not significant in the central region.Medium-scale capital farming and small-scale capital farming are the main forces to stabilize price fluctuation.However,the role played by large-scale capital farming is not obvious in stabilizing price fluctuation.

关 键 词：资本密集型养殖 养殖资本化 价格波动 稳定效应
