摘要
以新兴数字技术为代表的新质生产力是实现现代化产业体系的根本动力,也是推进粮食产业高质量发展与高水平安全的重要着力点。选取2012—2022年我国30个省份的面板数据,采用固定效应模型实证分析数字新质生产力对粮食产业发展与安全的影响、作用机制及区域差异。研究表明:数字新质生产力对粮食产业发展与安全具有显著的直接促进作用;粮食供应链韧性在数字新质生产力促进粮食产业发展与安全的过程中发挥了中介作用;数字新质生产力对粮食产业发展与安全的促进作用存在显著的区域异质性;数字新质生产力对粮食产业发展与安全的影响具有多重门槛效应。基于此,应完善农村新型数字基础设施建设,因地制宜制定协同推进策略,加强粮食供应链信息共享,构建分层推进、多维协同的干预体系,以促进粮食产业发展与安全。
Digital new quality productive forces,represented by emerging digital technologies,serve as the fundamental driving force for the modernization of industrial systems and a key focus for the high-quality and high-level security of the grain industry.Drawing on panel data from 30 provinces in China from 2012 to 2022,this study adopts a fixed-effects model to empirically investigate the effects of digital new quality productive forces on grain industry development and security,with particular attention to their mediating mechanisms and regional heterogeneity.The empirical results demonstrate that:digital new quality productive forces significantly and directly promote the development and security of the grain industry;grain supply chain resilience serves as a mediating mechanism in this relationship;notable regional heterogeneity exists in the magnitude of the effects;multiple threshold effects are identified in the influence of digital new quality productive forces on grain industry development and security.Therefore,policies should emphasize enhancing new-generation digital infrastructure in rural areas,developing regional-specific coordinated promotion strategies,strengthening information sharing within the grain supply chain,and establishing a stratified and multidimensional intervention system to foster both the development and security of the grain industry.
