| 【目的】在粮食安全日益受到全球和区域性外部冲击威胁的背景下，提升粮食供应链的韧性至关重要。本研究旨在探讨农业数字化能否显著增强粮食供应链的韧性，并深入分析其背后的作用机制。通过分析农业数字化在不同地区的影响差异，研究涉农财政补贴在推动农业数字化中的门槛效应，为政府和农业相关主体提供决策依据，从而提升粮食安全水平。【方法】基于2013-2022年中国31个省份的面板数据，运用基准回归和面板门槛模型，研究农业数字化对粮食供应链韧性的影响。稳健性检验包括替换解释变量、剔除直辖市样本和使用工具变量。以及进行了区域异质性分析，考察不同地区的差异，并检验涉农财政补贴的门槛效应。【结果】农业数字化显著提升了粮食供应链的韧性，特别是交易数字化在提升韧性方面发挥了关键作用。具体而言，农业数字化对粮食供应链韧性的提升系数为0.108（P<0.01），通过稳健性检验得到进一步验证。区域异质性分析显示，西部地区农业数字化对粮食供应链韧性的提升最为显著，中部地区次之，东部地区影响不显著甚至为负（-0.0604）。研究还揭示了涉农财政补贴存在门槛效应，当补贴水平超过0.8996时，农业数字化对供应链韧性的正向作用大幅提升，系数高达1.066（P<0.01）。【结论】农业数字化是提升粮食供应链韧性的重要途径，尤其是通过交易数字化加速信息流通和市场透明度提升。针对不同地区的差异，应充分利用其门槛效应，调整涉农财政补贴政策，推动区域性数字化交易平台的发展，从而全方位增强粮食供应链的稳定性和灵活性，确保粮食安全。 |

| 【Objective】In the context of increasing global and regional external shocks threatening food security, enhancing the resilience of food supply chains is of paramount importance. This study aims to investigate whether agricultural digitalization can significantly strengthen the resilience of food supply chains and to analyze the underlying mechanisms at play. By examining the differential impacts of agricultural digitalization across various regions, the research highlights the threshold effects of agricultural fiscal subsidies in promoting digitalization, providing a basis for decision-making for governments and agricultural stakeholders to enhance food security.【Method】Using panel data from 31 provinces in China between 2013 and 2022, this study employs baseline regression and a panel threshold model to examine the impact of agricultural digitalization on the resilience of the food supply chain. Robustness checks include replacing explanatory variables, excluding municipal samples, and using instrumental variables. In addition, regional heterogeneity is analyzed to investigate differences across regions, and the threshold effect of agricultural subsidies is tested.【Result】Agricultural digitalization has significantly enhanced the resilience of the food supply chain, with transaction digitalization playing a pivotal role in this improvement. Specifically, the coefficient for the impact of agricultural digitalization on food supply chain resilience is 0.108 (P<0.01), which is further validated through robustness checks. Regional heterogeneity analysis reveals that agricultural digitalization has the most significant positive effect on food supply chain resilience in the western region.The central region follows, while the eastern region shows an insignificant or even negative effect (-0.0604). The study also uncovers a threshold effect regarding agricultural fiscal subsidies, indicating that when subsidy levels exceed 0.8996, the positive impact of agricultural digitalization on supply chain resilience significantly increases, reaching a coefficient of 1.066 (P<0.01).【Conclusion】Agricultural digitalization is an important pathway for enhancing the resilience of the food supply chain, particularly through transaction digitalization, which accelerates information flow and increases market transparency. Given regional disparities, It is essential to leverage this threshold effect by adjusting agricultural fiscal subsidy policies and promoting the development of regional digital trading platforms, thereby enhancing the stability and flexibility of food supply chains and ensuring food security comprehensively. |
