摘　　要：针对当前我国耕地质量持续提升的迫切需求和农户有机肥技术采纳持续性较低的问题,基于蔬菜主产区6个省份的1667份农户调查数据,将信息能力纳入农户技术采纳决策模型,采用负二项回归和非参数Bootstrap方法,从理论和实证2个层面,对信息能力影响农户有机肥持续采纳行为的效果进行研究,并进一步验证收入不确定性的中介效应。结果表明:(1)信息能力在1%水平上显著促进农户有机肥持续采纳行为,边际效应为0.740;(2)信息能力对年龄≤52岁和受教育年限≥9年的农户的有机肥持续采纳行为影响最大,影响的边际效应分别为0.808和0.789;(3)收入不确定性在信息能力对农户有机肥持续采纳的影响中具有显著的中介效应,其边际效应系数为0.035。政府应适时更新农业技术推广形式、完善生产经营配套的信息技术基建设施、提供针对性的信息培训服务,凭借提高信息能力促进农户有机肥持续采纳。In view of the urgent need for continuous improvement of the quality of cultivated land and the problem of the low sustainability of farmers'adoption of organic fertilizer technology in China,this study analyses the effect of information competence and the mediating effect of income uncertainty on farmers'continuous adoption of organic fertilizer from the theoretical and empirical levels.The negative binomial regression and non-parametric Bootstrap methods are adopted to analyze 1667 original data from six main vegetable-producing provinces in China.The results show that:(1)Information competence has a significant positive impact on farmers's continuous adoption of organic fertilizers at the 1%level,with a marginal effect of 0.740;(2)Information competence has the greatest impact on the continuous application of organic fertilizers of farmers with age≤52 years old(the 50th percentile)and who have been educated≥9 years,with marginal effects of 0.808 and 0.789,respectively;(3)Income uncertainty has a significant mediating effect on the influence of information competence on farmers'continuous adoption of organic fertilizer,with marginal effect coefficient of 0.035.Therefore,to improve the sustainability of farmers'adoption of organic fertilizers,the government should update the form of agricultural technology promotion,improve the information technology infrastructure facilities,and provide targeted information training services and so on to improve their information competence.
