摘要

将小农户纳入新兴的细粒和芳香 "优质大米"(PQR)价值链可能被证明是改善孟加拉国农村生计的关键所在,尽管农民的农艺知识水平参差不齐可能会制约这方面的努力。根据预先分析计划,我们对 PQR 主要产区的 1420 位农民进行了调查,分析了农民在 PQR 种植中有效分配增产投入的能力。农民们收到了一份假定的预算,用于分配建议用于高效生产 PQR 的六种不同投入,模拟了他们自己农场的季节性生产决策。我们的研究结果表明,即使没有预算或投入品获取方面的限制,农民在这种假设情况下也倾向于低效分配 PQR 的投入品。特别是,他们往往会在种子、化肥和农药上超支。相反,通过 PQR 专项推广服务等途径获得更多农业信息的农民,其效率得分会大幅提高,并决定大幅减少化肥支出。如果今后不进行调整,如提供更有针对性的推广服务,那么隐含的较高生产成本很可能会降低小农种植 PQR 的利润率,从而限制潜在的收入增长。除了这些经济方面的问题,过度使用投入也会带来环境外部效应。因此,从经济和环境角度来看,提高效率都是可取的。

Can information constraints explain the low efficiency in premium quality rice cultivation? Evidence from smallholder farmers in Bangladesh

The integration of smallholder farmers into emerging value chains for fine-grain and aromatic ‘premium quality rice’ (PQR) could prove to be crucial to improving rural livelihoods in Bangladesh, though efforts could be constrained by farmers' differing levels of agronomic knowledge. Based on a pre-analysis plan, we analyse farmers' ability to efficiently allocate production enhancing inputs in PQR cultivation based on a survey of 1420 farmers in key PQR producing areas. Farmers received a hypothetical budget to allocate to six different inputs advised for efficient production of PQR, mimicking familiar production decisions made seasonally on their own farms. Our results suggest that even without budget or input access constraints farmers tend to inefficiently allocate inputs in PQR in this hypothetical setting. In particular, they tend to overspend on seeds, fertiliser and pesticides. Farmers with better access to agricultural information, such as through PQR specific extension services, conversely reach substantially higher efficiency scores and decided to spend significantly less on fertiliser. Without future adjustments such as more targeted extension services, implied higher production costs will likely lower the profitability of PQR cultivation for smallholder farmers, thereby limiting potential income gains. Besides these economic concerns, excessive input use is associated with environmental externalities. Improved efficiency is therefore desirable from both an economic and environmental standpoint.

期刊介绍: Published on behalf of the Agricultural Economics Society, the Journal of Agricultural Economics is a leading international professional journal, providing a forum for research into agricultural economics and related disciplines such as statistics, marketing, business management, politics, history and sociology, and their application to issues in the agricultural, food, and related industries; rural communities, and the environment. Each issue of the JAE contains articles, notes and book reviews as well as information relating to the Agricultural Economics Society. Published 3 times a year, it is received by members and institutional subscribers in 69 countries. With contributions from leading international scholars, the JAE is a leading citation for agricultural economics and policy. Published articles either deal with new developments in research and methods of analysis, or apply existing methods and techniques to new problems and situations which are of general interest to the Journal’s international readership.
