尽管近年来发展中国家对发达国家的水产养殖出口有所增长，但由于不符合国际标准，这些产品在发达国家港口被拒收的比例很高。本文介绍了越南虾类养殖部门的一个案例研究，以研究这种港口拒绝持续存在背后的因素。我们特别关注为什么许多农民没有适当地采用所谓的更好的管理实践（BMP），并检查信息源的数量和类型是否对农民采用BMP的决定有影响，以及BMP的采用是否真的会带来更好的绩效。根据我们在越南南部收集的原始数据进行的估计，我们发现信息来源和培训经验确实对采用更多BMP有影响，并且BMP的采用确实降低了疾病爆发的可能性。这些结果证明了bmp的有效性，并表明通过专家向农民传播有关bmp的知识的重要性。
Despite the growth of aquaculture exports from developing countries to developed countries in recent years, a high percentage of these products are rejected at developed countries’ ports because of non-compliance with international standards. This paper presents a case study of the shrimp aquaculture sector in Vietnam to examine the factors behind the persistence of such port rejections. In particular, we focus on why the so-called better management practices (BMPs) are not appropriately adopted by many farmers and examine whether the number and types of information sources matter in farmers’ decisions on BMP adoption and whether BMP adoption actually leads to better performances. On the basis of our estimation using primary data collected in Southern Vietnam, we find that information sources and training experiences indeed matter in the adoption of a higher number of BMPs and that BMP adoption indeed reduces the possibility of disease outbreaks. These results prove the effectiveness of BMPs and suggest the importance of disseminating knowledge regarding them to farmers through experts.
