城市化进程中的公共物品引致供需分析

随着城市化的不断发展，对原有公共物品的需求会不断增加，同时一些新的公共物品需求也会随之产生，从而产生公共物品供给不足。一般而言，按照公共物品理论，政府是公共物品的主要供给者。但是，由于存在政府失灵与政府失败，公共物品的政府单一供给模式未必是最具效率的。因此，针对城市化进程中所产生的公共物品供给不足，应分析其基本特征，选择最优的供给模式。

On Analysis of Causing Demand and Supply during Urbanization

With the increase development of urbanization, the primary demands to public goods will increase, at the same time, some new demands to public goods will also come into being. Consequently, supply of public goods will be insufficient. Generally, according to the theory of public goods, government is the primary provider. However, being of government malfunction and government failure, the pattern of government being the single provider of public goods maybe is not the most efficient. So, aiming at the insufficiency of public goods supply during the course of urbanization, we should analyze its basic characters and choose the best supply pattern.
