食品供应链对于将商品从生产点分配到消费点至关重要。这些复杂的供应链对粮食安全和可得性至关重要。最近的研究已经开发出新的方法来估计高空间分辨率的食物流动，但我们目前还不了解细粒度食物供应链如何随时间变化。在本研究中，我们使用改进版本的粮食流量模型来估计2007年、2012年和2017年所有粮食商品组的所有县对之间的粮食流量（公斤）（需要估计2.063亿个链接）。然后，我们通过多标准决策分析技术确定美国粮食流动网络的核心国家。我们对县与县之间粮食流动的估计可以在本文中免费获得，这可能对未来的研究、政策和决策有用。
Food supply chains are essential for distributing goods from production to consumption points. These complex supply chains are important for food security and availability. Recent research has developed novel methods to estimate food flows with high spatial resolution, but we do not currently understand how fine-grained food supply chains vary in time. In this study, we use an improved version of the Food Flow Model to estimate food flows (kg) between all county pairs across all food commodity groups for the years 2007, 2012, and 2017 (which requires estimating 206.3 million links). We then determine the core counties to the US food flow networks through time with a multi-criteria decision analysis technique. Our estimates of county-to-county food flows in time are freely available with this paper and could be useful for future research, policy, and decision-making.
