Abstract
Many factors have various effects on urban land use. It is indispensable to analyze the effects through interdisciplinary approach using the methodology of studies on law, economics and engineering for the increase of the social surplus. The legislation of the fixed term tenancy to solve the problem caused by the rent control and restriction on dissolution in the tenancy law is one of the examples of fruits derived from such successful researches. Research studies are needed hereafter through the interdisciplinary approach to create a new and appropriate criterion for the dissolution of the social confusion of urban landscape.
