摘要

在水稻种植中滥用化肥、杀虫剂和除草剂,导致产出质量低、生产成本高、健康问题和环境问题(如土壤质量退化、水污染和温室气体增加)。有效利用生产投入是缓解这些问题的可行方法。本文采用真实随机效应模型来衡量成本效率,并调查影响越南水稻生产者成本效率低下的因素。本研究使用了在越南湄公河三角洲收集的 350 个稻米家庭的调查数据。研究结果表明,成本效率的平均值为 0.92,差异较大(0.26 - 0.99)。这项研究表明,效率低下的水稻生产者仍有潜力通过提高成本效率来节约生产成本。研究还揭示了成本效率低下与农场规模、自然灾害和水稻病害之间的正相关关系。这表明,随着农场规模的扩大,自然灾害和水稻病害的发生率会越来越高,水稻生产者管理投入成本的能力也会越来越弱。本研究建议,扶持政策应侧重于提高稻农管理生产投入、应对稻病和自然灾害的技能,以最大限度地降低稻米生产成本。

Estimating cost efficiency and sources of inefficiency in paddy farming: A study in Vietnam’s Mekong Delta
The misuse of chemical fertilizers, pesticides and herbicides in rice cultivation is leading to low-quality outputs, high production costs, health issues and environmental problems (e.g., degraded soil quality, water pollution and increasing greenhouse gases). The efficient use of production inputs would be a feasible way to mitigate these issues. This paper employed a true random-effects model to measure cost efficiency and investigate the factors affecting cost inefficiency among Vietnamese rice producers. This study used the surveyed data of 350 rice households collected in the Mekong Delta, Vietnam. The findings of this research show that the mean cost efficiency score is 0.92 with a wide variation (0.26 – 0.99). This study indicates that there is still potential for inefficient rice producers to save production costs by improving their cost inefficiency. The study also reveals a positive relationship between cost inefficiency and farm size, natural disasters and rice diseases. This suggests that as farms grow, natural disasters and rice diseases become more prevalent and rice producers become increasingly incapable of managing input costs. This study suggests that supportive policies should focus on improving rice farmers’ skills to manage production inputs and deal with rice diseases and natural disasters to minimize rice production costs.
