Empirical studies on the energy-efficiency of compact city have been conducted mainly for the low-density dispersed Western cities. Given the tendency of high population densities of Korean cities, uncovering the impact of additional compactness on energy efficiency requires empirical testing. However, most empirical studies in Korea tend to rely on data limited to a city of specific location or size, or overlook important factors such as socioeconomic variables which would be closely related to energy consumption. This paper investigates the applicability of the compact city using the 1998-2005 annual data on the 7 densely populated metropolitan cities, including not only urban form characteristics but also socioeconomic variables. The results show that a net population density is negatively related with transportation energy consumption. In particular, it is estimated that a 1% increase of a net residential density saves gasoline by 55~88 million dollars per a year. The findings point to the positive effect of compactness on energy-efficiency, which suggests that compact city still can be a sustainable urban form in Korea.
