【摘要】 耕地质量是粮食生产的根基，保障粮食安全是建设农业强国的首要目标。文中基于东北黑土区887份农户数据，运用Biprobit模型实证分析了政府激励、感知价值及交互作用对农户黑土地保护意愿与行为的影响。结果表明：不同维度政府激励对农户黑土地保护意愿与行为的影响存在差异，项目型政策显著促进了农户黑土地保护意愿向保护行为转化，补贴型政策显著提升了农户的保护意愿；感知经济价值促进了农户黑土地保护的意愿与保护行为，感知环境与社会价值显著提升了农户的黑土地保护意愿，但并未能转化成保护行为；政府激励与感知价值存在着交互作用，既体现在其内部也体现在二者之间；政府激励、感知价值对黑土地保护意愿及行为的影响存在规模异质性。更多还原

【Abstract】 The quality of cultivated land is the foundation of grain production, and ensuring food security is the primary goal for building a powerful agricultural country. Based on the data of 887 farmers in the northeast black soil region, Biprobit model was used to empirically analyze the effects of government incentives, perceived value and interaction on farmers’ willingness and behavior to protect black land. The results show that there are differences in the effects of different dimensions of government incentives on farmers’ willingness and behavior to protect black land. Project-type policies significantly promote the transformation of farmers’ intention of black land protection into protection behavior, and subsidy-type policies significantly improve farmers’ intention of protection. Perceived economic value promotes farmers’ intention and behavior of black land protection. Perceived environmental and social values significantly improve farmers’ intention of black land protection, but do not transform into protection behavior. There are interactions between government incentives and perceived values, or inside themselves. The effects of government incentives and perceived values on black land protection intention and behavior are characterized by scale heterogeneity.更多还原
