摘　　要：数字经济为粮食产业高质量发展提供了新契机和新动能。文章基于新发展理念,从供给、创新、协调、绿色、开放、共享六个维度构建粮食产业高质量发展水平的综合评价体系,深入分析数字经济影响粮食产业高质量发展的理论逻辑,并基于2011—2021年的省级面板数据进行实证检验。研究发现:数字经济能够显著提升粮食产业高质量发展水平,实证结果在一系列稳健性检验后依然成立。异质性分析结果显示,东部地区数字经济对粮食产业高质量发展的驱动作用大于中西部地区,同时这种驱动作用在粮食主销区最大,其次是产销平衡区,在粮食主产区最小;作用机制检验结果显示,数字经济主要通过技术创新(微观)、产业结构优化(中观)、粮食市场整合(宏观)赋能粮食产业高质量发展;非线性效应检验结果显示,数字经济对粮食产业高质量发展的影响存在单一门槛,当数字经济发展水平跨越该门槛时,其对粮食产业高质量发展的促进作用进一步增强。The development of digital economy provides new opportunities and new dynamics for the high-quality development of grain industry.Based on the new development concept,this paper constructs a comprehensive evaluation system for the level of high-quality development of the grain industry from the six dimensions of supply,innovation,coordination,green,openness and sharing,then makes an in-depth analysis of the theoretical logic of digital economy influencing the high-quality development of the grain industry,and finally uses provincial panel data from 2011 to 2021 to conduct an empirical test.The research finds that digital economy can significantly improve the level of high-quality development of the grain industry,which still holds after a series of robustness tests.Heterogeneity analysis results show that the driving effect of digital economy on the high-quality development of the grain industry is greater in the eastern region than in the central and western regions,while this driving effect is greatest in the main grain marketing area,followed by the balanced production and marketing area,and least in the main grain producing area.Mechanism test results show that digital economy mainly enables the high-quality development of grain industry through technological innovation(micro),industrial structure optimization(meso),and grain market integration(macro).Nonlinear effect test results show that there is a single threshold for the impact of digital economy on the high-quality development of grain industry,and that when the development level of the digital economy crosses the threshold,its contribution to the high-quality development of the grain industry is further enhanced.
