摘　　要：利用甘肃省民勤绿洲调研数据,运用无序多元Logit回归模型,实证分析了信息获取渠道、学习能力对农户灌溉技术选择偏好的影响。研究发现:农户获取信息的渠道具有多样性,且不同信息渠道对不同类型技术选择的影响效应存在差异,社会网络对简单技术采用的边际影响较大,而政府推广对复杂技术采用的边际影响较大;学习能力对农户节水灌溉技术采用具有促进作用。建议拓宽农户基于政府推广和社会网络的信息获取渠道,并针对不同类型节水灌溉技术,结合技术复杂程度和农户学习能力,制定最优的推广方案。Based on survey data of Minqin oasis in Gansu Province, we use a multivariate logit model to empirically analyze how informational channels and learning ability affect farmers＇ water - saving irrigation technology adoption behavior. Our findings suggest that extension services and social network channels both have significant impact on farmers＇ irrigation technology selection; different information channels exist differences effects on different types of technology： marginal effects of social network on simple technology is relatively big, while extension service channel on complex technology is relatively big; learning ability can promote farmers＇ future drip and pipe irrigation technology adoption. We should broaden both informational channels, design better promotion strategy combined with technology complexity and farmers＇ learning ability.
