This study examines the role of agricultural socialized services in promoting steady growth in grain production in China. Using panel data from 2007 to 2020, the research employs the Entropy Method to assess the dynamic changes in agricultural socialized services that contribute to increased grain production. The study uses static panel, mediator, and threshold regression models to investigate the effects and mechanisms of agricultural socialized services on grain production growth. The empirical findings show a significantly positive correlation between enhanced agricultural socialized services and increased grain production. This positive impact persists even with limited grain production resources. A mediating effect was identified, where agricultural socialized services indirectly stimulate grain production growth by encouraging large-scale agricultural land management. Threshold analysis indicates the presence of a single threshold effect linked to the level of agricultural socialization services. This threshold effect plays a pivotal role in the relationship between large-scale agricultural management and steady grain production growth. The study suggests that enhancing agricultural socialized services can promote sustained growth in grain production. The study also explores the influence of agricultural socialized services on farmers' income, showing that these services can effectively increase farmers' earnings by aligning production factors with grain farmers, reducing production costs, and increasing income from grain management. The study's main contributions include a comprehensive examination of agricultural socialized services, empirical rigor through extensive temporal analysis, quantified positive correlation between services and grain production, mechanistic insights into the positive impact, and addressing regional disparities and threshold effects. The findings highlight the importance of agricultural socialized services in promoting grain production growth and food security in China. The study's results provide empirical evidence supporting the role of agricultural socialized services in enhancing grain production and offer policy implications for sustainable grain production.This study examines the role of agricultural socialized services in promoting steady growth in grain production in China.
