针对存在外部经济时的资源配置问题,利用机制设计的方法,设计了实现效率与公平的资源配置方案的机制。即使投入产出函数不是所有参与人的共同知识,只需要所有参与人都知道投入产出函数,该方法就能达到预期效果。为存在外部经济时实现社会最优的资源配置方案提供了一种新的解决方案。 Aiming at the problem of resource allocation in the presence of external economy, a mechanism of resource allocation to achieve efficiency and fairness is designed by means of mechanism design.
