公共品供给中的政府责任

Government Responsibilities in the Supply of the Public Goods

在公共品供给中,政府责任是提供它需要并且能够提供的公共品。需要提供的公共品是指在现有的资源技术条件下,达到社会效用最大化所需提供的公共品。能够提供的公共品是指征到拉弗曲线隐含的最大税收量所能提供的公共品。需要并且能够提供的公共品是指需要提供的公共品与能够提供的公共品中量较小的一方。通过比较政府实际提供的公共品与需要并且能够提供的公共品,可以评价政府在这一领域称职与否。

In the supply of public goods, government responsibility is to provide the public product that is needed and can be offered. The public goods demanded refer to the amount of goods needed to maximize social utility under the condition of the existing resource and technique. Public goods that can be offered are the amount limited by the maximal tax revenue implied in laffer curve. Public goods that is needed and can be offered refers to the smaller amount. By comparing the amount the government offered actually and that needed and can be offered, we can appraise the government and fill a post with credit or not in this field.
