摘要
采用超越对数随机前沿生产函数模型和来自山西省晋中市、万荣县和平陆县3个主产区的苹果种植农户的调研数据,对苹果种植户当前的投入产出状况、技术效率差异及造成差异的主要因素进行实证分析.结果表明,调查的样本农户技术效率在52.48％～98.36％之间,平均技术效率值是82.34％.在技术效率的影响因素中,果农的种植经验和种植规模对技术效率都有正面的影响且具有统计显著性,即生产经验和种植规模对当前苹果种植户技术效率有明显的促进作用.
Using tanslog stochastic frontier production function model and a large set of first hand household level survey data from apple growers in Shanxi Province to measure the input/output status,technical efficiency of Shanxi apple growers and the influencing factors.The results show that：the technical efficiency of survey sample households is at 52.48％-98.36％,with an average of 82.34％; And the experience of producers,the growing scale and regional dummy variables are statistically significant,in which growers experience and the planting scale have significant positive effects on technical efficiency.
