Under the urbanization, climate change, and global market fluctuation, ensuring national food security is very important for China. This study researched the relationship between land use efficiency and food security within China’s major grain-producing provinces. Using a panel dataset spanning 2010 to 2022, the research adopt Ordinary Least Squares (OLS) regression analysis to search how variations in grain output per hectare affect per capita grain availability. The findings show a significant positive relationship, showing that provinces with higher land productivity are more effective at securing local food supply. Notably, provinces like Heilongjiang and Jilin demonstrate high levels of land use efficiency and higher food security, whereas provinces with lower efficiency can be more vulnerable to food shortages. This study provides critical views into optimizing agricultural productivity through technological innovation, land intergration, and sustainable resource management, contributing valuable recommendations for policy interventions aimed at enhancing national and regional food security.
