Subway development project influences on the real estate pricing especially on the price of apartment houses. Moreover the presence of subway station gives a good reason for inhabitants to live by or for investors to buy promising lands or properties. Accessibility is a thumb important factor influencing on buyer’s decision making process to buy “good things” in Seoul or near metropolitan areas.

This study aims to analyze the effects of the Sinbundang Subway Line Development Project on nearby house prices. The researcher dig the data from the commencement of the project to the completion of stations and digitalized the various degrees of influences and the reliable results of the development according to the construction periods.
Difference-in-Differences method is adopted because Difference-in-Differences is useful for comparing the practical effects before and after the enforcement of policies. Also Quantile Regression Method is used for analyzing the quantile-based price effect.
This study confines research target within the apartment houses at Pungdeokcheon-dong and Jukjeon-dong in Yongin city. These residential complex located within the lineal distance of subway station either 500m or 1000m each. These sites near the Suji-gu Office Station were not included in the station influence_ area until the completion of Sinbundang Subway Line.
The house price data this work deals based on the reports by the Ministry of Land, Infrastructure, and Transport. The whole period covers from the commencement of the development of Sinbundang Subway Line project to the completion of subway. As the ground breaking ceremony opened on July 2010, so the first target period is set from July 2009 to June 2011. And the line completion event hold on September 2015 thus next target period stretches from September 2014 to August 2016.
Analyzing with Difference-in-Differences method on the effect of Sinbundang Subway Line construction, the prices of apartment houses apart 1,000m or 500m from Suji-gu–Office station increased in amostl model cases. But the exception of pricce increase occurred after one year when the subway station construction started.
Because the apartment houses within 500m diameter from the Suji-gu-Office Station already have been affected by the semi-station-area influence, the strength of the influence caused by the Sinbundang Subway Line Development Project is more strongly sensible. Before the opening of the Sinbundang Subway Line, the commutators and passengers of Jukjeon station in Bundang Subway Line are well aware of and expected the promising increase of the house price. In reality, the price increase came true. Along with the improvement of accessibility and transportation since the opening of Sinbundang Subway Line, price increase appears higher within 1000m areas from stations.
As for the Sinbundang Subway Line development phases, interesting point is that the effect of the start of the subway line construction is more influential than that of the completion.
Quantile Regression Method analysis reveals that the influence of the construction commencement gradually decreases from lower quantile to 50% quantile. However, from the 50% quantile to upper quantile, it shows no big variation. In case of whole opening of subway line, the influence on price increase shrinks from lower quantile to upper quantile, and the significance level also decreases gradually, and in 90% quantile, the influence is not significant any longer.
This study has three merits :
first, with the Difference-in-Differences method it minimizes the influences of various external factors such as macroeconomic situations and regional differences and measures the direct effects of the subway development project on house price changes,
second, with Quantile Regression Method and Difference- in-Differences method together it finds out the various patterns of influence caused by the subway construction on the apartment house prices,
and third, it takes advantage of the Difference-in-Differences method, commonly used to measure the public policy efficiency in order to point out the impact and consequences of the subway development project as a large-scale.
