At the same time, due to doubling the limits of rational existence, the mechanism also suffers from a series of difficulties.The redesign and perfection of the system based on the dual rational will be beneficial to get out of an effective anticorruption road in the countryside.

摘要： 针对近年农村基层腐败风险加大，四川乐山市通过探索村纪检机制打通了权力监督的“最后一公里”。基于双重理性考察，这一制度的设计与功能基于个体理性视角呈现出规则中心、博弈论、委托—代理三种模式，公共理性给予这一制度保障支撑。同时，双重理性限度的存在致使村纪检制度遭遇系列困境。基于双重理性的制度再设计与完善，有利于走出一条有效的农村基层反腐之路。
