摘要

本研究采用随机前沿生产函数方法测量了Mwanza地区小农玉米生产的技术效率及其决定因素。在这两个地区随机抽取参与者样本。采用极大似然估计方法,得到了番茄小规模生产者技术效率和技术效率水平的决定因素。技术效率的最小值和最大值在20% ~ 91%之间,表明特定生产者的最低实践运行在最低20%的技术效率水平,而最佳实践生产者运行在91%的技术效率水平。平均技术效率的总结结果为57%。结果表明:农户技术效率不完全,平均技术效率得分为0.58;该研究还表明,大多数农民,无论其持股规模大小,都表现出技术效率低下的问题。据观察,经验丰富的农民对技术效率有很好的衡量标准。农户技术效率的显著变量包括农户规模、劳动力、肥料、种子、文化程度、农户规模、农业经验和推广服务的可及性对农户技术效率有显著的正向影响。

Smallholder Tomato Production in Mwanza Region- A Technical Efficiency Analysis Approach.
This study measured technical efficiency and its determinants in maize production by small-scale producers in Mwanza region, using a stochastic frontier production function approach. A randomly selected sample of participants in the two districts was used. The Maximum Likelihood estimation procedure was followed to obtain the determinants of technical efficiency and technical efficiency levels of small-scale tomato producers. The minimum and maximum values of technical efficiency were between 20% and 91%, indicating that the least practices of specific producer operates at a minimum level of 20%, while the best practice producers  operate  at 91% technical efficiency level respectively. The summary results of the mean technical efficiency was 57%. The results indicate that farmers were not fully technically efficient with a mean technical efficiency score of 0.58. The study also revealed that most of the farmers irrespective of the size of the holdings have shown technical inefficiency problems. Experienced farmers were observed to have good measures of technical efficiency. The findings also indicated that significant variables of technical efficiency included household size, labour, fertilizer, seed, educational level, household size, farming experience, and access to extension services were statistically significant by positively impacted on producers’ technical efficiency in the study area.
