本研究旨在阐明农业技术采用对减贫战略的潜在影响。它这样做，通过经验调查技术变革之间的关系，绿色革命类型，在孟加拉国两个农村地区的小农农户的福祉。由于技术采用不是随机分配的，但有“自我选择治疗”，本文解决了一个方法学问题，通过非参数的“p-得分匹配分析”，评估技术对农户福祉的“因果”影响。它力求有针对性地评估采用现代种子技术是否会使资源贫乏的农民提高收入，并减少落入贫困线以下的倾向。它发现了一个强大的和积极的影响，农业技术的采用对农户的福祉，这表明有一个很大的空间，以提高农业技术的作用，“直接”促进扶贫。(C)2006爱思唯尔有限公司版权所有。
This study aims at shedding some light on the potential impact of agricultural technology adoption on poverty alleviation strategies. It does so through an empirical investigation of the relationship between technological change, of the Green Revolution type, and wellbeing of smallholder farm households in two rural Bangladeshi regions. As technology adoption is not randomly assigned but there is 'self-selection into treatment', the paper tackles a methodological issue in assessing the 'causal' effect of technology on farm-household wellbeing through the non-parametric 'p-score matching analysis'. It pursues a targeted evaluation of whether adopting a modern seed technology causes resource-poor farmers to improve their income and decrease the propensity to fall below the poverty line. It finds a robust and positive effect of agricultural technology adoption on farm household wellbeing suggesting that there is a large scope for enhancing the role of agricultural technology in 'directly' contributing to poverty alleviation.
