本研究旨在分析尼泊尔奇旺地区玉米生产的成本效率，以期使用随机前沿成本函数预测经济效率。主要数据收集自180玉米农民代表12个村发展委员会（VDCs），包括一个直辖市的地区在2005年5月至6月的种植年2004-2005。在各种因素中，粪肥的使用在生产成本中所占比例最高，其次是劳动力和拖拉机成本。参数的最大似然（ML）估计表明，估计系数的拖拉机，畜力，劳动力，肥料，粪肥，种子和玉米产量的成本给了积极的系数，并在5%的水平显着。此外，从成本函数中获得的定量估计显示，平均成本效率为1.634，表明研究中的平均玉米农场的成本比边界成本高出约63%，这表明效率低下。此外，低效率模型中户主和玉米面积的受教育年限表明这些因素对农场的成本效率产生了积极影响。通过对玉米种植场规模效应的分析，发现玉米种植场的规模收益是递增的，即玉米产量的增加比例大于总生产成本的增加比例。
This study was carried out to analyze the cost efficiency of maize production in the chitwan district, nepal with a view to predict economic efficiencies using stochastic frontier cost function. The primary data were collected from 180 maize farmers representing 12 village development committees (VDcs) including one municipality of the district during May–June 2005 for the cropping year 2004–2005. Among various factors, use of manure accounted the highest share in the production cost followed by labour and tractor costs. The maximum-likelihood (ML) estimates of the parameters revealed that estimated coefficients of cost of tractor, animal power, labour, fertilizer, manure, seed and maize output gave positive coefficients and were significant at 5% level. Further, quantitative estimates obtained from the cost function shows the mean cost efficiency of 1.634 indicating that an average maize farms from the study incurred about 63% costs above the frontier cost-an indication of inefficiency. Also, the significant years of schooling of the household head and maize area in the inefficiency model indicated the positive effect of these factors on cost efficiency of the farms. From the analysis of scale effect among maize farms, it was revealed that the maize farms experienced an increasing return to scale, that is, the output increased more proportionately than the total production cost.
