低保制度作为中国社会救助体系中兜底性的核心制度安排,在实践中捆绑了大量的救助资源,这导致低保对象和其他低收入群体间的收入差距出现扩大的趋势,不利于增强“提低”效果和推动共同富裕。本文基于中国家庭追踪调查和中国家庭金融调查的样本数据,运用模糊断点回归的方法实证检验了不同时期农村低保制度的捆绑效应,并进行了政策模拟分析。结果发现,低保捆绑效应在脱贫攻坚时期不断放大,低保家庭获得的专项救助远高于其他低收入家庭,其中在危房改造、医疗健康和教育补助方面的差异尤为明显。进一步政策模拟发现,将低保捆绑的其他社会救助全部或部分转移至其他低收入群体,可以在不增加财政负担的前提下,缩小低收入群体内部的收入差距,提升社会救助的有效性。因此,本文建议打破低保的捆绑效应,更好地发挥社会救助的“提低”作用。
