中文摘要：带状复合种植技术提供了农业可持续与粮油稳产保供的途径,但在大范围推广中能否促进农业绿色高效发展仍待验证.文中利用西南、西北和黄淮海地区带状复合种植技术推广村的农户调研数据,测算当前大豆玉米生产的环境效率,并运用内生转换模型实证分析带状复合种植技术对农业环境效率的影响.结果表明:1)当前大豆玉米生产的环境效率整体存在改进空间,同时考虑碳排放、氮盈余和碳吸收,才能充分衡量采纳该技术带来的效益.2)农户采纳带状复合种植技术能够显著提高农业环境效率.基于反事实假设,复合种植户若未采纳复合种植技术,其农业环境效率将下降5.01%.3)带状复合种植技术对农业环境效率的提升作用在不同推广区域、农户与技术采纳规范度之间存在差异.据此,可以采取优化技术推广布局、增强推广政策精准性以及强化技术示范和培训的措施,促使技术进一步发挥效果.

外文标题：Does relay strip intercropping technology improve agricultural environmental efficiency?:Case study in the Southwest,Northwest,and Huanghuaihai regions of China

外文摘要：Maize-soybean relay strip intercropping technology(MRSIT)provides a way to promote sustainable agriculture and food supply security,yet evidence at the farmer level is still needed to determine whether it can promote green and efficient development of agriculture in large-scale promotion.Based on the research data from farmers in the Southwest,Northwest and Yellow Huaihai regions,this paper measures the environmental efficiency of the current Chinese soybean and maize production,and evaluates the impact of MRSIT on the agricultural environmental efficiency by using an endogenous switching model.The results of this study showed that:1)Overall,there is room for improvement in the environmental efficiency of current soybean and corn production.It is only by considering carbon emissions,nitrogen surplus,and carbon absorption that we can fully assess the benefits of adopting the MRSIT.2)Farmers'adoption of MRSIT can significantly improve environmental efficiency.Under a counterfactual assumption,if farmers do not adopt the MRSIT,their agricultural environmental efficiency is expected to decline by 5.01%.3)The improvement effect of farmers'MRSIT adoption varies among different extension regions,different types of farmers and different degrees of standardization.Accordingly,measures such as optimizing the layout of technology promotion,enhancing the precision of promotion policies,and strengthening technology demonstration and training should be taken to promote greener and more efficient agriculture.
