Abstract
Areas where houses and factories are mixed are typical of the established urban districts in question. For firstly, the 2 issues are complexed and concentrated ; (1) Local public nuisance made by factories and cars are impacting the enviroment. (2) And the housing is over-densely inhabited and damaged. Secondarily these mixed land use areas take up 25〜30% of urban districts in metropolitan areas. The purpose of studying these mixed land use areas where work and dwelling are compounded is to understand the urban structure and to improve the environmental quality in these districts. There are 3 methods of explaining the structure of these districts; (1) The environmental conditions in the concentrated industrial districts are seen as a factor of the production's social division of labor and the organizational structure of the industrial (parent industry and subsidiary) complex. (2) A detailed analysis of how the managerial level can improve the factory environment. (3) Where industry and housing are inseparated but adjacent area. Factries pervasive enviromental influences that an industrial areas impacts onto the surrounding residential neighborhoods.
