农村数字化与粮食供应链韧性:理论机制、经验证据及政策选择

Rural Digitization and Food Supply Chain Resilience:Theoretical Mechanisms,Empirical Evidence and Policy Options

选取2011-2021年的省级数据,构建粮食供应链韧性和农村数字化的综合指标体系,运用固定效应模型探究农村数字化对粮食供应链韧性的影响,研究发现:农村数字化的发展能够提升粮食供应链韧性;异质性检验结果表明,农村数字化对粮食供应链韧性的正向效应在中部地区最强,西部地区最弱。因此应重视农村数字化转型在粮食供应链韧性提升中的重要作用、实现农村数字化转型阶梯式发展,以提高我国粮食安全的可靠性。

Selecting provincial data from 2011-2021,this paper constructs a comprehensive index system of food supply chain resilience and rural digitization,and explores the impact of rural digitization on the resilience of the food body supply chain using the fixed effect model,and finds that:the continuous development of rural digitization can enhance the resilience of the food supply chain,and the results of the test of heterogeneity show that the positive effect of rural digitization on the resilience of the food supply chain is the strongest in the Central region,and the weakest in the northeast region.Therefore,in the future,we should pay attention to the important role of rural digital transformation in improving the resilience of the food supply chain,realize the stepwise development of rural digital transformation,and improve the reliability of China's food security.
