In order to account for a price variation of apartment that places near a newly constructed subway station, a spatial hedonic model was developed to examine spacial characteristics that affect a purchasing price of an apartment using a White Estimator. In particular, the paper aims to examine various effects of subway 7 construction on an apartment price in Seoul Metropolitan Area. As explanatory variables, an apartment size, distance to a closest subway station, distance to the Central Business District (CBD) of Seoul, the number of years after building, and a lagged variable of the apartment purchasing price were used. The lagged variable plays a role of representing a spatial weighted average of previous prices of other apartments that locate within 3km from the apartment. For a precise study, an entire sample was divided into two sets, southern area and southwestern area of Seoul, and two different spatial hedonic models were estimated. Not only before and after analysis, but also with and without analysis were conducted to compare with different effects of the spatial characteristics of two areas. The results show that before the construction of the subway 7, the prices of the apartments in the southern area were more sensitive to the apartment size, the distance to a closest subway station, the distance to the CBD, and the prices of the other apartments locating within 3km rather than those in the southwestern area. After the construction, on contrast, it is found that the apartment purchasing prices in the southwestern area are more sensitive than those in the southern area due to people's expectation regarding a new development around the subway station. In addition, the prices of the apartments locating closely with a transfer station are more likely to go up by increase in the apartment size, the distance to the station, and the prices of the other apartments within 3km, Compared with the negative effects of the distance to the station on the prices in the other models, the positive effect of the distance to the transfer station might be caused by the characteristics of commercial area in which people are not likely to live.

This study is to solve a problem of elementary school facilities' insufficiency in the reconstruction area of Ichon 1-Dong in Seoul. Results of this study are as follows; 529 students will be increased to Shinyongsan elementery school in 2004; 1,206 students will be increased after the reconstruction projects is completed in Ichon 1-Dong. By accepting these students I suggest alternatives in three aspects; the application of the existing facility, the establishment of new school facilities and the constraint of student demand by reconstruction development. There are some limitations and more themes must be solved. First of all, the flexible standards corresponding to various community's characteristics such as a builtup area or a new development area are needed. Secondly, the community plan must be prepared for many urban developments in a community area. Thirdly, reconstruction development must have an alternative for establishing public facilities. Lastly, the decision making system reflecting the communities' goals must be required to choose the best alternative for the community's public facilities.
