一项制度的外部监管失效或监管成本高昂的时候,再按这个思路做出的解决方案就是失灵的。公车消费监管失灵的原因在于其公有资源的外部性,并且由于信息不对称公民很难参与监督。本文试在公车使用中引入一个自我约束机制,以期实行公车消费的货币化改革,从根本上解决问题。 When a system fails to regulate itself or its regulatory costs are high, a solution based on this thinking is failure. The reason for the failure of bus consumption regulation lies in the externalities of its public resources, and it is very difficult for citizens to participate in the supervision due to the asymmetric information. This paper attempts to introduce a self-restraint mechanism in bus use, with a view to implementing the monetization reform of bus consumption and fundamentally solving the problem.
