Abstract: In terms of urban planning, the impact of urbanization and high density on the environment is a major issue. This study intended to analyze the effect of spatial density characteristics of urban air pollution sources on urban air pollution concentration using a panel model. As the total population density, the number of cars registered per capita, and the total emission facility density increased, together with a closer distance to a thermal power plant, the nitrogen dioxide(NO 2 ) concentration increased. Net population density was also found to have the greatest impact on the structure and density of emission sources of ozone(O 3 ) followed by the number of cars registered per person and the total emission facility density. It was confirmed that particular matter(PM 10 ) concentrations are strongly influenced in positive directions by the spatial density characteristics of emission sources that show significant differences between regions.
