Carbon peaking, carbon neutrality goals and food security are the basis of sustainable development, and exploring the coordination relationship between China's agricultural eco-efficiency and food security system has a major significance for the implementation of relevant strategies. This paper is based on collaboration research on the synergistic relationship between agricultural eco-efficiency and food security systems using methods such as entropy weight method, coupling coordination model, spatial autocorrelation model, etc., revealing the evolution-driven mechanism of the coupling coordination degree. This study found that a higher level of coupling coordination always occurs in those areas with high standard farmland construction and large grain production scale, while economically developed areas appear to have a lower overall coordination level limited by endowment constraints and division of labor in development planning. It shows a positive spatial correlation in terms of geographical distance between agricultural eco-efficiency and food security, and the positive spillover effect gradually increases but is not strong overall. China should combine regional resource endowment and development planning, pay attention to the improvement of large-scale and standardized agricultural production, continue to strengthen the development of clean agricultural production, and achieve food security under the constraints of the carbon peaking and carbon neutrality goals.
碳达峰、碳中和目标与粮食安全是可持续发展的基础，探讨中国农业生态效率与粮食安全系统的协调关系，对于实施相关战略具有重大意义。本文基于熵权法、耦合协调模型、空间自相关模型等协同研究方法，揭示了农业生态效率与粮食安全系统的耦合协调度演变驱动机制。研究发现，高标准农田建设水平和粮食生产规模大的地区往往存在更高水平的耦合协调，而经济发达地区受禀赋约束和发展规划分工的影响，整体协调水平较低。农业生态效率与粮食安全之间存在显著的地理距离空间相关性，且正溢出效应整体上逐渐增强但并不强烈。中国应结合区域资源禀赋和发展规划，注重大规模和标准化农业生产的提升，持续加强清洁农业生产的发展，在碳达峰、碳中和目标的约束下实现粮食安全。
