주거지역 근린환경에서 발생하는 양(陽)과 부(負)의 외부효과의 상쇄현상에 관한 연구

Due to the growth of incomes and increases in environmental concerns, the neighborhood amenity of the residential areas are becoming as much a decisive factor of the households’ residential choices as the housing unit characteristics and the site conditions. As well known, the residential areas are subject to the externalities accrued from their neighborhood environment due to their spatial fixity. In the inner city areas, especially, there frequently exist places where both positive- and negative externalities are simultaneously exerted in complex urban settings. In such cases, it is hardly expedient to properly differentiate the magnitude of the interactions, and the trade-offs between such opposite sources of externalities. The study, in this context, tries to quantitatively measure and differentiate such conflicting impacts, taking the Han-River Civic Park and the adjacent riverside highways as the case, since the former is considered as the prototypical source of positive externalities while the latter the counterpart. Via the hedonic estimation technique, the study segregates the opposite influences and fits separate explanatory models from the aforementioned sources of positive- and negative externalities.
