Investigating the spatial heterogeneity characteristics and driving factors can provide decision-making reference for scientifically managing the non-agricultural use of cropland in the Huang-Huai-Hai region. The article uses a comprehensive evaluation method, OLS model, spatial autocorrelation analysis, and geographically weighted regression model to study the spatial heterogeneity characteristics and driving factors of non-grain cultivation in the Huang-Huai-Hai region. The research results show that from 2008 to 2022, the non-grain cultivation rate in the Huang-Huai-Hai region presented a spatial distribution pattern of "north high south low and east high west low", with significant regional spatial differences, mainly characterized by high-high clustering and low-low clustering. The level of non-grain cultivation is affected by the joint action of agricultural, social, economic, and policy factors. Among them, rural residents' consumption expenditures, agricultural subsidies, urbanization rate have a greater impact on the level of non-grain cultivation in the region, while the difference between urban and rural residents' disposable income, the total power of agricultural machinery per unit of cultivated land, and per capita GDP also have an impact on its spatial heterogeneity characteristics to varying degrees. During the research period, the level of non-grain cultivation in the Huang-Huai-Hai region has an upward trend, and the spatial differences are obvious. In the future, precision management of non-grain cultivation should be implemented by adjusting the preferential policies in a targeted manner, improving the compensation mechanism for grain production, strengthening the construction of soil quality and protection of cultivated land, to ensure China's food security.
