社会效益是衡量公共投资社会效益的一个术语。利益分为直接利益和间接利益。根据计算方法，它们还分为基于原产地的福利或基于发生率的福利。社会福利的计算，一般是以来源为基础进行计算。在本文中，我们假设一个封闭的经济，并分析的情况下，在发病率的基础上的利益大于那些在原产地的基础上。假设的经济具有马歇尔类型的外部经济。自由放任均衡不同于社会（帕累托）最优均衡。分析了税收和补贴的庇古处方，通过市场均衡实现帕累托最优均衡。税收和补贴制度考虑到了科斯定理。我们假设公路投资是在管理经济中的公共投资项目。对两种效益进行了计算，并进行了比较。
The social benefit is a term to measure the social usefulness of the public investments. Benefits are termed direct benefits or indirect benefits. They are also classified into origin basis benefits or incidence basis benefits based on the calculation method. To calculate the social benefits generally means the calculation based on the origin basis. In this paper, we assume a closed economy, and analyse the case where the benefits on the incidence basis are greater than those on the origin basis. The assumed economy has external economies of the Marshallian type. The laissez-faire equilibrium is different from the social (Pareto) optimum equilibrium. The Pigouvian prescription of tax and subsidy is analysed to realize the Pareto optimum equilibrium through the market equilibrium. The system of tax and subsidy takes account of the Coase Theorem. We assume the public investment project of highway investments in the managed economy. The two types of benefits of the project are calculated, and compared with each other.
