Abstract

This study employed the input-oriented DEA approach with variable returns to scale assumption to assess the technical, scale, allocative and economic efficiencies of 124 randomly selected tomato farmers under irrigation in the Upper East Region using data of the 2017/2018 production season. The mean technical efficiency and scale efficiency were 97.1 and 97% respectively with many farmers experiencing increasing returns to scale. The mean allocative and economic efficiencies were 42.1 and 41.5% respectively. Farmer’s age, tomato land size, fuel quantity, fertilizer quantity and chemical quantity (herbicide and pesticide) were all significant determinants of technical efficiency scores whereas extension visit, tomato land size and chemical quantity significantly influenced both allocative and economic efficiencies. It is recommended that agro-inputs and fuel usage for tomato farmers under irrigation in the dry season be increased to improve technical efficiency. It is also recommended that extension education to farmers on effective inputs allocation and cost minimization strategies be intensified. Key words: Allocative, economic and technical efficiency, data envelopment analysis, Tobit regression, tomatoes, Upper East Region of Ghana

加纳上东部地区灌溉番茄生产效率评价

本研究采用投入导向DEA方法和可变规模回报率假设，利用2017/2018生产季节的数据，评估了上东部地区124名随机选择的灌溉番茄农户的技术、规模、配置和经济效率。平均技术效率和规模效率分别为97.1%和97%，许多农民的规模回报率不断提高。平均配置效率和经济效率分别为42.1%和41.5%。农民的年龄、番茄土地面积、燃料量、肥料量和化学品量（除草剂和农药）都是技术效率得分的重要决定因素，而扩展访问、番茄土地大小和化学品量则显著影响配置效率和经济效率。建议增加旱季灌溉番茄农民的农业投入和燃料使用量，以提高技术效率。还建议加强对农民的有效投入分配和成本最小化战略的推广教育。关键词：分配，经济技术效率，数据包络分析，托比特回归，番茄，加纳上东部地区
