摘　　要：探究农业科技投入对农业生态效率的影响,对促进农业生态建设、推动农业高质量发展具有重要意义。文章基于2011—2022年我国31个省区市(除港澳台地区)的面板数据,采用Super-SBM模型测算各省区市12年的农业生态效率值;通过固定效应模型检验农业科技投入对农业生态效率的直接影响;利用中介模型与门槛模型检验间接影响。结果表明:我国农业生态效率整体呈现上升态势;区域间呈现东部地区快速增长、中西部地区缓慢增长的特征。农业科技投入正向显著影响农业生态效率,农业抗灾能力发挥部分中介作用,农业劳动生产率发挥单门槛作用。因此,建议差异化增加区域农业科技投入;发展智慧农业,持续提升农业抗灾能力;提高农业生产劳动率,运用现代化生产技术改善农业生态效率。Exploring the impact of agricultural science and technology investment on agricultural ecological efficiency is of great significance for promoting agricultural eco-construction and high-quality development of agriculture.Based on the 2011—2022 panel data of 31 provinces,autonomous regions and municipalities(excluding Hong Kong,Macao and Taiwan region)in China,the Super-SBM model was used to measure the 12-year agroecological efficiency values of each province,autonomous region and municipality;the direct impact of agricultural science and technology investment on agricultural ecological efficiency was tested by the fixed effect model;and the indirect impact was tested by using the mediator model and the threshold model.The study showed that:Agricultural ecological efficiency in China as a whole showed an upward trend,with rapid growth in the eastern region and slow growth in the central and western regions.Agricultural science and technology investment positively and significantly affected agricultural ecological efficiency.Agricultural science and technology investment positively and significantly affected agroecological efficiency.Agricultural disaster resistance played a partially mediating role,and agricultural productivity played a single-threshold role.Therefore,it is recommended to differentiate and increase regional investment in agricultural science and technology,develop smart agriculture,continuously improve agricultural disaster resistance increase agricultural productivity,and to improve agricultural ecological efficiency by using modern production technologies.
