Ensuring food security in the new development paradigm urgently requires increasing the grain supply chain resilience. The data of 31 provinces in China from 2011 to 2021 are select to demonstrate the relationship between the digital economy, government innovation-driven and grain supply chain resilience. In order to clarify how the government can effectively perform its macro-regulatory functions, the government innovation-driven is reflected by government innovation-driven planning and government innovation-driven investment, respectively. The study shows that: (1) Digital economy has a stronger enhancement effect on grain supply chain resilience; (2) Government innovation-driven has an increased moderating effect on digital economy enhance grain supply chain resilience; (3) The enhancement effect of digital economy and moderating effect of government innovation-driven both are differentiated between China’s functional zones of grain production; (4) The threshold effect of government innovation-driven planning shows a process of digestion and absorption, which accumulating to 0.018 will emerge a multiplier effect. Government innovation-driven investment is higher than 0.026, which can have a promoted moderating effect. To expand the depth of integration of the digital economy, accurately government innovation-driven, focus on attracting innovative talents, which can construct the perpetual motion machine mode of “external promote + internal drive”, so as to strengthen the robustness of grain supply chain.
