农业技术效率的提高是农业增长的重要源泉。采用甘肃省定西市马铃薯生产的数据,运用超越对数函数形式的随机前沿模型,对马铃薯生产技术效率及影响因素进行研究。结果表明:种植面积对大规模地块的影响要大于小规模地块,马铃薯的劳动密集型生产使大规模地块的技术效率比小规模地块受到更多限制;劳动时间对种植面积的影响在达到一定规模后随着种植面积的增加而增大;化肥使用量只有在达到最低规模后才开始发挥正向影响。土壤质量、性别和年龄的平方项对技术效率有重要影响,教育水平和种植经验的影响却不显著。由此,提出提高马铃薯种植技术效率的建议:一是根据技术水平和要素资源合理选择适当规模的地块进行种植;二是农户应加大对规模较大地块的畜力、劳动时间和化肥的投入,以尽可能提高大规模地块的生产技术效率;三是不断改良地块土壤质量,加强农户的种植技能培训。

Agricultural technology efficiency is one of the most important sources of agricultural growth. Based on potato production data from Dingxi city of Gansu province, this paper uses stochastic frontier production model in translog form to analyze the technical efficiency and its influencing factors. The result shows that impact of planting area on large scale land is bigger than that on small-scale land, the labor-intensive production of potato has more limitation in large-scale land than that in small-scale land. Among the input factors, the effect of labor time on the planting area will enlarge with the increase of planting area when reaching a certain extent,the quantity of fertilizer use begins to exert positive in- fluence only when it reaches a minimum size. In addition, the soil quality, gender and the square of age have important impact on technical efficiency, while education and planting experience have no significant effect. Therefore, this paper puts forward to three suggestions on how to improve the efficiency of potato planting. First, choosing appropriate scale of planting land according to technology level and resources; second, farmers should increase the investment in animal power, labor time and chemical fertilizer for large scale lands to improve their efficiency; finally, soil quality of plots should be improved and training of farmers' planting skills should also be strengthened.
