本文利用来自四川省成都市313户农户的调查数据，在森的可行能力框架下运用模糊评价方法,评价了成都市具有不同经济发展水平的各圈层区域农民集中居住后的福利变化。结果发现：（1）农户福利水平在集中居住后有一定程度的提高，但在不同经济发展水平的圈层之间，集中居住前后农户福利变化的差异较大，经济发展中等水平的第二圈层农户福利改善水平显著高于经济发展水平较高的第一圈层，而经济发展水平较低的第三圈层农户福利水平则有所下降。（2）集中居住改善了农户的居住条件、社会保障、社区活动和社会资源等功能，但恶化了农户家庭经济状况与居住环境。据此提出的相关政策建议是：结合圈层特点促进就业，改善农民家庭经济状况；增强社区绿色治理能力，改善农民居住生态环境；加大公共服务投入力度，改善农民总体福利水平。
