The people are the foundation of the nation, and grain is vital for their survival. Food security is crucial for national stability and well-being. This study utilizes panel data from 1,234 counties in China's primary grain-producing regions, covering the years 2010 to 2021, to conduct a theoretical analysis and empirical examination of the impact of farmland management rights mortgage loans (FMRML) on food security, employing a difference-in-differences (DID) model. The empirical results indicate that the pilot policy significantly enhances food security in major grain-producing areas. Moreover, the conclusions remain robust following parallel trends and placebo tests. Mechanism analysis reveals that the policy can promote food security by increasing rural mechanization and boosting financial support in rural areas. Heterogeneity analysis demonstrates that factors such as regional resource endowments, economic development levels, and farmland tenure systems can lead to varying effects of the policy on food security. This research provides valuable references and insights for global practices aimed at enhancing food security through policies enabling the mortgage of farmland management rights.
民以食为天，粮稳国安。粮食安全关乎国家稳定与民生福祉。本研究运用2010年至2021年中国主要粮食产区1234个县的面板数据，采用双重差分模型（DID），对农地经营权抵押贷款（FMRML）对粮食安全的影响进行理论分析与实证检验。实证结果表明，试点政策显著提升了主要粮食产区的粮食安全水平。此外，经过平行趋势检验和安慰剂检验，研究结论依然稳健。机制分析显示，该政策可通过提高农村机械化水平和加大农村金融支持力度来促进粮食安全。异质性分析表明，区域资源禀赋、经济发展水平和农地权属制度等因素会导致该政策对粮食安全产生不同影响。本研究为全球旨在通过农地经营权抵押政策保障粮食安全的实践提供了有价值的参考和启示。
