| 摘 要： | 以民勤县农户层面调研数据为基础,采用两阶段DEA-Tobit分析方法,对农户苜蓿生产效率进行测度,并对影响技术效率的因素进行分析。DEA测度结果表明,样本地区苜蓿种植成本效率为0.532,存在较大提升空间;规模效率为0.872,表明苜蓿种植规模已趋于成熟,规模收益可扩展空间及发展潜力不大,仅为12.8%。Tobit分析结果显示,温度、户主受教育程度、机械使用次数以及新技术的使用均对苜蓿种植技术效率有显著的正向作用。 |

| Abstract: | We applied the DEA-Tobit method to estimate the productivity efficiency of alfalfa growers and analyzed the factors affecting technical efficiency, using the field survey data obtained from Minqin County in China.DEA results showed that the cost efficiency was only 0.532, implying room for improvement, with a scale efficiency of 0.872, implying limited potential for development.Tobit results indicated that temperature, educational background of household head, experience of using machinery, and the use of new technology had significantly beneficial impacts on alfalfa growers' technical efficiency. |
