数字能力对粮食绿色生产效率的影响研究
Impact of digital capability on grain green production efficiency:Evidence from major maize-producing regions in Southwest,Northwest,and Huang-Huai-Hai region of China
摘要
Abstract
Under the dual objectives of ensuring food security and promoting agricultural green transformation,exploring the impact of digital capability on grain green production efficiency is of great practical significance for improving the quality and efficiency of grain production and advancing high-quality agricultural development.Based on survey data from 537 maize farmers,this study measures maize green production efficiency using the super efficiency SBM model and empirically examines the effect of digital capability on green production efficiency through a Double Machine Learning approach.The results indicate that:1)Digital capability significantly improves maize green production efficiency,and this conclusion remains robust after a series of robustness tests,including winsorization,alternative sample-splitting ratios,alternative machine learning algorithms,and alternative measures of the core explanatory variable.2)Mechanism analysis reveals that digital capability enhances green production efficiency through three pathways:strengthening green cognition in the pre-production stage,promoting technology adoption during production,and improving price responsiveness in the post-production stage.3)Heterogeneity analysis reveals that the positive effect of digital capabilities on maize green production efficiency is more pronounced among farmers with better infrastructure conditions and those using socialized services,while the effects differ across dimensions of digital capabilities.Based on these findings,this study suggests strengthening farmers' digital capability,improving rural digital infrastructure and agricultural digital service systems,and promoting the deep integration of digital technologies with green agricultural production,thereby facilitating the green transformation of grain production.关键词
