This study examines the impact of agricultural socialized services on grain production growth in China from 2007 to 2020. Using panel data and the Entropy Method, the research employs static panel, mediator, and threshold regression models to analyze the effects and mechanisms of these services. The findings show a significant positive correlation between enhanced agricultural socialized services and increased grain production, even with limited resources. The services indirectly stimulate grain production growth by encouraging large-scale agricultural land management. Threshold analysis indicates a single threshold effect linked to the level of agricultural socialization services, which plays a crucial role in the relationship between large-scale management and steady grain production growth. The study suggests that enhancing agricultural socialized services can promote sustained growth in grain production, addressing regional disparities and threshold effects. The results have significant implications for policy formulation and strategic initiatives aimed at ensuring food security in China and other regions facing similar challenges.This study examines the impact of agricultural socialized services on grain production growth in China from 2007 to 2020.
