【摘要】 减少耕地撂荒、提高耕地资源利用效率，是保障粮食安全的重要途径。本文基于8省(市)53县105村1767户调查数据，在利用实验经济学方法测度农户风险态度的基础上，借助Logit模型探讨了风险态度对农户土地撂荒行为的影响及其作用机制，并进一步分析了土地确权在其中起到的调节作用。研究结果表明：风险态度对农户撂荒行为产生显著正向影响，风险偏好程度越高，农户土地撂荒行为发生率越高；土地确权在其中发挥了重要的调节作用，即土地确权强化了风险态度对农户土地撂荒行为的影响；风险态度对农户撂荒行为正向影响主要体现在经济水平低的家庭、未使用农业社会化服务农户和中西部家庭中。因此，需弱化农户主观意识，发挥政府引导作用，拓宽土地利用形式，推动土地流转，从而减少撂荒行为发生。更多还原

【Abstract】 Reducing cultivated land abandonment and improving the utilization efficiency of cultivated land resources are critical pathways to ensuring food security. Based on survey data from 1,767 households across 105 villages in 53 counties of 8 provinces and municipalities, this study employs experimental economics methods to measure farmers’ risk attitudes and applies a Logit model to investigate the impact of risk attitudes on farmland abandonment behavior, as well as the moderating role of land tenure certification. The results reveal that: 1)Risk attitudes exert a significantly positive effect on farmland abandonment, higher risk preference levels lead to a higher incidence of farmland abandonment among farmers. 2) Land tenure certification plays a crucial moderating role, amplifying the influence of risk attitudes on abandonment behavior. 3)The positive effect of risk attitudes is particularly pronounced among low-income households, farmers not using agricultural socialized services, and households in central and western regions. Therefore, policymakers should mitigate the impact of farmers’ subjective perceptions, enhance government guidance, diversify land-use options, and promote land transfer, thereby reducing the occurrence of land abandonment.更多还原
