在传统经济学中,公共物品作为市场失灵的重要表现,被认为必须由政府来供给。科斯的《经济学中的灯塔》通过对英国灯塔供应的现实对这一观点进行了挑战,提出了公共物品私人供给的观点。本文在对科斯的观点进行批判的基础上,分析了公共物品的产权特性,比较了在其产权界定和生产的不同方式。从而得出了政府在公共物品的供给中所应起到的作用。本文的最后将将这一讨论延伸到政府在社会主义市场经济建设中与市场职能的结合问题。 In traditional economics, public goods, as an important manifestation of market failure, are considered to have to be supplied by the government. Coase’s “Lighthouse in Economics” challenged this view by presenting the reality of the British lighthouse supply and put forward the idea of ​​private supply of public goods. Based on the criticism of Coase’s point of view, this article analyzes the property rights of public goods and compares the different ways of defining and producing property rights. Thus the government should play a role in the supply of public goods. Finally, this article will extend this discussion to the government’s combination of market functions with the socialist market economy.
