Most of studies on Mitigation Banking System (MBS) which is the mechanism to compensate the environment destroyed by development in the U.S. mainly focus on its advantages, limitations and administrative viewpoints, although its remarkable futures is the application of market mechanism. Few studies discuss the economic impacts on each stakeholder in the market mechanism. This paper aims to investigate such impacts on five agents in a road project: government, mitigation banker, landowner, resident, and private firm. With five developed individual economic models and the benefit incidence table, it was found the cost to conserve environment was shared by whole society because the road organization allocated the tax revenues from each agent to the budget of compensatory mitigation. The perception on the MBS benefit and cost flows through a marketing mechanism is useful not only for Japan, but also for any places planning to implement MBS for protecting their environments.
