摘　　要：节粮减损不仅是我国的优良传统,也是高质量发展背景下保障国家粮食安全的迫切需要。文章基于2012—2019年上市涉粮流通企业的面板数据,考察了节粮减损对企业全要素生产率的影响及作用机制。结果显示:节粮减损对全要素生产率具有显著的促进作用。基于中介效应的检验表明,提高物质资本配置水平、人力资本配置水平以及技术创新水平是节粮减损提升企业全要素生产率的重要机制。基于调节效应的检验表明,数字化水平对节粮减损与企业全要素生产率的关系具有正向的调节作用。考虑企业的异质性特征后,节粮减损对全要素生产率的促进作用在不同性质、地区、存续年限及数字化水平的企业中存在差异。因此,需要重视节粮减损对企业发展的影响,通过优化资本配置、提升技术创新以及企业数字化水平等渠道,全面夯实中国粮食安全根基。Grain-saving and loss-reducing is not only our country’s fine tradition,but also the urgent need to ensure national food security under the background of high-quality development.Based on the panel data of listed grain-related circulation enterprises from 2012 to 2019,this paper examines the impact and internal mechanism of grain-saving and loss-reduction on the enterprise total factor productivity.The results show that grain-saving and loss-reducing can promote the total factor productivity of enterprises.Based on the test of mediation effect,it is found that improving the allocation of physical capital,human capital and technological innovation are important mechanisms to improve the enterprise total factor productivity.Based on the test of moderation effect,it is found that the digital level has a positive moderating effect on the relationship between grain-saving loss-reducing and total factor productivity.Considering the heterogeneity of enterprises,the promotion effect of grain-saving and loss-reducing on total factor productivity is different among enterprises with different ownership,regions,years of existence and digitalization level.Therefore,it is necessary to stress the impact of grain-saving and loss-reducing on the development of enterprises,through the optimization of capital allocation,technological innovation and digital level to consolidate the foundation of food security in China.
