| 【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. |
