中文摘要：

研究目的：探讨不同类型农户退地决策及重要影响因素。研究方法：以重庆市实地调查数据,运用B-Logistic模型进行定量分析。研究结果：（1）户主年龄、家庭主要成员参加新农保、承包地面积对纯农户土地退出决策产生显著正向影响,而家庭劳动力数量、宅基地面积、承包地质量对纯农户土地退出决策产生显著负向影响;（2）家庭劳动力数量、家庭年均收入、家庭年均农业收入、宅基地面积、承包地质量、所在村距城镇距离对I兼农户土地退出决策产生显著负向影响,而家庭主要成员参加新农保则对I兼农户土地退出决策产生显著正向影响;（3）家庭年均收入、家庭年均非农收入对II兼农户土地退出决策产生显著正向影响,而农房造价对II兼农户土地退出决策产生显著负向影响;（4）家庭年均收入、家庭年均非农收入、所在村距离城镇距离均对非农户土地退出决策产生显著正向影响;（5）总体来看,影响纯农户与I兼农户的土地退出决策的因素具有较大相似性,而影响II兼农户与非农户的土地退出决策的因素也具有较大相似性。研究结论：不同类型农户土地退出决策及影响因素存在显著差异,地方政府有必要制定差别化的退地政策,鼓励与引导II兼农户与非农户退出土地。
