摘要
耦合效率能够表征商品型生态农业系统的耦合效果,因此,利用数据包络分析(DEA)方法,对安塞县商品型生态农业发展态势进行了测度和评价。结果表明:在要素配置方面,安塞县商品型生态农业的投入要素之间存在着替代性,要重视要素的合理配置。在耦合效率方面,安塞县商品型生态农业的综合效率变化不大,多数年份的效率值在0.85以上,但技术效率呈现随机波动,规模效率相对较低,最低值为0.658,规模报酬多数年份表现为递增态势,说明个体小规模的农业经营模式已经不能适应新技术、新政策背景下农业的发展需求,即安塞县的商品型生态农业的发展需要扩大经营规模,以提高规模效率,同时促进新技术的效率发挥。
Coupling efficiency can characterize the coupling effect of the ecological agriculture with commodity economy system,the data evelopment（DEA） analysis method was used to measure and evaluate the development trend of the ecological agriculture with commodity economy in Ansai county.The results showed that there was alternative among the input factors of the ecological agriculture with commodity economy in Ansai county from the factor allocation aspect,so attention should be paid to the rational allocation of factor.From the coupling efficiency aspect,the overall efficiency of the ecological agriculture with commodity economy in Ansai county changed a little and the efficiency values of the most years were greater than 0.85,but the technical efficiency showed random fluctuations,the scale efficiency was relatively slow and the minimum value was 0.658 and the returns of scale in most years presented increasing returns to scale.All these showed that individual and small-scale farming systems can not adapt to the need of agriculture development in the context of the new technology and the new policy,that is to say the development of ecological agriculture with commodity economy in Ansai county needs expand scale of operation to improve the scale efficiency and to promote the new technical efficiency at the same time.
