【摘要】 揭示农村流通数字化对粮食体系韧性影响的内在逻辑，对于加速农村流通数字化进程、助力数字化赋能粮食体系韧性与安全水平提升具有重要意义。在理论机理分析的基础上，基于2011～2021年省级面板数据，实证检验了农村流通数字化对粮食体系韧性的影响效应。主要结论为：(1)基准回归显示，农村流通数字化能够显著提升中国粮食体系韧性，经过一系列稳健性检验并消除内生性问题后，该结论依然成立。(2)异质性检验显示，农村流通数字化对中、西部地区以及粮食主产区的粮食体系韧性有更显著的促进效果。(3)中介模型检验显示，产业融合、农业技术创新在农村流通数字化对粮食体系韧性的正向影响中发挥了中介效应。(4)门槛效应检验显示，农业劳动生产率在农村流通数字化对粮食体系韧性的影响中发挥着门槛作用。据此，未来应加快推动农村流通体系数字化转型，重视产业融合、农业技术创新的中介作用和劳动生产率的门槛影响，因地制宜激发农村流通数字化对粮食体系韧性的赋能效应。更多还原

【Abstract】 Revealing the inherent logic of the impact of digitalization of rural circulation on the resilience of the grain system is of great significance for accelerating the process of digitalization of rural circulation and helping to empower the resilience and security level of the grain system with digitalization.On the basis of theoretical mechanism analysis, based on provincial panel data from 2011 to 2021, this paper empirically tested the impact of rural circulation digitalization on grain system resilience. The main conclusions were:(1) Benchmark regression showed that digitalization of rural circulation could significantly enhance the resilience of China’s grain system. After a series of robustness tests and elimination of endogeneity issues, this conclusion still held.(2) Heterogeneity testing showed that digitalization of rural circulation had a more significant promoting effect on the resilience of the grain system in the central and western regions, as well as the main grain producing areas.(3) The intermediary model test showed that industrial integration and agricultural technology innovation played mediating roles in the positive impact of rural circulation digitization on the resilience of the grain system.(4) The threshold effect test showed that agricultural labor productivity played a threshold role in the impact of digitalization of rural circulation on the resilience of the grain system.Therefore, in the future, we should accelerate the digital transformation of the rural circulation system. We should further consider the importance of the intermediary roles of industrial integration and agricultural technology innovation and the threshold impact of labor productivity. The empowering effect of rural circulation digitization on the resilience of the grain system should also be stimulated, according to local conditions.更多还原
