公共品需求偏好显示机制：一个理论回顾

摘要

公共品的需求偏好显示是公共经济学理论中的一个难题。长期以来,经济学家一直试图建立有效的公共品需求偏好显示机制,以实现公共品的最优供给。文章从理论发展的视角对投票机制、价格拍卖机制、特征价格机制和或有估价机制这几种主要偏好显示机制进行了回顾和总结,直到今天,这些机制仍然是经济学家们继续探索的领域。%It is difficult to reveal consumer＇s preference for public goods.In order to realize the optimal supply of public goods,economists have been attempting to set up some preference reveal mechanisms on public goods for decades.This paper discusses some mechanisms from the view of theories development.These mechanisms include voting theory,auction theory,hedonic pricing and contingent valuation method.
