Environmental problems caused by automobiles are most serious among urban environmental problems. However automobiles play much important roles in the field of private or industrial transport, so urban environmental projects to control automobile use are afraid to give damages to socioeconomy through the increase of automobile using cost. So it is need to evaluate synthetically the economized environmental policies by calculating the economic loss due to executing these policies. In this paper, we build the computable general equilibrium (CGE) model consider location equilibrium to evaluate socioeconomic impacts when implementing the urban environmental projects. And we actually computed the impacts of some urban projects at Osaka in Japan and confirmed movements of our CGE model. JEL classification: R12, R13, R52
