摘要
为了探讨种植面积、养殖规模与农户家庭奶牛养殖生产效率之间的关系,本研究基于奶牛养殖户微观调研数据,利用数据包络分析(data envelopment analysis,DEA)方法测算了农户家庭奶牛养殖生产效率,并运用Malmquist指数法分析了种养结合对农户家庭奶牛养殖生产效率的提升效果,同时采用Tobit模型分析了种植面积与养殖规模对养殖生产效率的影响。结果表明:奶牛养殖全要素生产率为1.0722,大于1.0000,种养结合有助于农户家庭奶牛养殖生产效率的提升;种养分离下种植面积在10%水平上显著正向影响奶牛养殖纯技术效率,种养结合下种植面积在5%水平上显著正向影响奶牛养殖纯技术效率,种植面积的扩大有利于农户家庭奶牛养殖生产效率的提高;在种养分离与种养结合下养殖规模均在1%水平上显著正向影响奶牛养殖纯技术效率,扩大养殖规模有利于提高奶牛养殖生产效率。鉴于此,笔者提出要鼓励和支持奶牛养殖户开展种养结合,鼓励奶牛养殖户适当扩大种植与养殖规模,加强对奶牛养殖户养殖技术的宣传与培训力度。
In order to explore the relationship between planting area,breeding scale and the efficiency of dairy farming,based on the micro-survey data of dairy farmers,this study used data envelopment analysis(DEA)to measure the efficiency of dairy farming in households,and used Malmquist index to analyze the effects of breeding combination on the improvement of dairy farming efficiency in households.At the same time,Tobit model was used to analyze the effects of planting area and breeding scale on breeding efficiency.The results showed that the total factor productivity of dairy farming was 1.0722,which was greater than 1.0000,and the combination of planting and breeding was helpful to improve the efficiency of dairy farming.Under the separation of farming and breeding,the planting area significantly positively affected the pure technical efficiency at the level of 10%,and under the combination of farming and breeding,the planting area significantly positively affected the pure technical efficiency at the level of 5%.The expansion of planting area was conducive to the improvement of dairy farming efficiency of peasant families.In both breeding separation and breeding combination mode,the farming scale had a significant positive effect on the farming pure technical efficiency at the level of 1%,and expanding the farming scale was conducive to improving the farming efficiency of dairy cows.In view of this,the author proposed to encourage and support dairy farmers to carry out the combination of planting and breeding;encourage dairy farmers to appropriately expand planting and breeding scale;strengthen the publicity and training of dairy farmers'breeding techniques.
