【摘要】：以干旱区绿洲农业典型区张掖市甘州、临泽、高台三县区为例,在投入产出专项调查基础上增补调查内容,利用DEA-Tobit模型分析不同类型农户大田玉米生产效率和影响因素。结果表明:(1)三县区大田玉米综合技术效率存在21.9%的提升空间,其中纯技术效率提升空间大于规模效率,说明种植技术运用程度低是效率不高的主要原因。(2)小规模农户生产效率较高,大规模种植户可通过加大机械化生产、节水灌溉规模等措施,提高生产效率。(3)种植业收入、务工收入、温度与大田玉米生产效率呈显著正相关性;补贴收入、化肥农药用量、种植面积与大田玉米生产效率呈显著负相关性。
[Abstract]:In the arid oasis region of agriculture in Zhangye city Ganzhou, Linze, Gaotai County in three as an example, the input-output special investigation based on the supplementary investigation content, using DEA-Tobit model analysis factors of different types of farmers corn production efficiency and effect. The results showed that: (1) the overall technical efficiency of Maize Field in three counties area there are 21.9% of the room among them, the pure technical efficiency is greater than the space to improve the scale efficiency, which means that planting technology using low degree is the main reason for not high efficiency. (2) small scale farmers and high production efficiency, large scale growers can increase mechanization production, water-saving irrigation scale measures to improve production efficiency. (3) the income of planting workers income was positively correlated with the temperature field of corn production efficiency; income subsidies, the amount of chemical fertilizer and pesticide, there was a significant negative correlation between planting area and production efficiency of the corn field.

【正文快照】： 大田玉米是我国西北干旱区绿洲农业地区重要的粮食、饲料来源,科学评估大田玉米生产效率,进而提出效率改进措施对提高农民收入、保障粮食安全具有重要意义。上世纪九十年代以来,我国大田玉米的整体种植技术不断发展,生产效率不断提高,然而西北地区大多数农户依然是粗放式种植,
