가로경관개선이 지가에 미치는 영향요인분석

Overhead transmission lines placed in a disorder manner in urban areas can cause serious damage to human and material resources when disaster occurs. If the overhead transmission lines will be placed underground, we can secure a safer and more pleasant side walk, improve the urban landscape, and provide a stable power supply. Moreover, we assume that overhead transmission lines affect both the price of land and decisions to measure economic value of affected real estate. However, for insufficient cost, placing power transmission lines underground is not promoted. We assume the fundamental reason for the lack of projects is that there are few studies that have measured the economic benefit of such projects and how they affect local residents. Therefore, the purposes of this study are to research and analyze changes in land prices before and after a project to place transmission lines underground through time series, and to measure how the project influences economic values of land. We chose Deasungro district region, Chuncheon city, Gang Won province, as the subject study area to analyze price differences between the project area and areas of the surroundings in 2010, when the project ended, and experimentally analyze how the project affected price changes through the Hedonic price model. As a result of our study, we found a positive correlation between the project to place transmission lines underground and the price of the land where the project took place. Augmented public benefits from the underground lines have influenced the price of the land. At the same time, the coefficient of regression of the project decreased between 2010 and 2015. Meanwhile, the coefficient of regression of Land Use Condition1 and Land Use Condition2 increased respectively. These results mean that improving public benefits by burying transmission lines affected the prices of the target areas through the land use conditions. Thus, we assume that changes in land values are not because of the value of the project itself, but because those values reflect the characteristics of residential and commercial areas. Recently, evaluation of the value of urban landscapes and safe areas for walking has come into the picture. This study is intended to prove how the underground line project influences the price of the project area, and to discover a new factor impacting prices of land. However, because of a short period for collecting study data, we focus on a cross-section study, and cannot consider the actual prices of the subject areas.
