英文摘要China faces a critical spatial imbalance between its agricultural water/land resources and food production, threatening national food security. To address this, this study analyzes available agricultural water-land resources and food production data from 335 prefecture-level Chinese cities (2000-2020) to measure spatial imbalance and explore its underlying drivers. Panel regression models are employed to examine the determinants of water-food and land-food imbalance. Results show that over 20 years, available agricultural water and land declined by 9.96% and 19.39%, respectively. Notably, 46.76% of cities improved their water-food imbalance, while 35% improved their land-food imbalance. Regression results indicate that higher grain yield, yield per unit area, and agricultural employment exacerbate imbalance, whereas mechanization and urbanization alleviate them. The positive association between water-food imbalance and land-food imbalance suggests a mutually reinforcing effect that may accelerate systemic spatial imbalance within the water-land-food nexus. This study provides a novel prefecture-level agricultural water-land dataset and offers evidence for region-specific policies to optimize resource allocation and strengthen China's food security.
