택지개발지구 단독주택용지내 상업용도 침투의 영향요소 분석 : 청주시 사례를 중심으로

택지개발지구 단독주택용지의 상업용도 침투 요인을 분석했다.

The housing policy in our country has been performed emphasizing quantitative provision of house for enhancing housing supply ratio, and though the results of these policies have led to achieve housing supply ratio above 100%, now we should emphasize the qualitative aspect of housing environment rather than the quantitative aspect. The purpose of this study is to investigate the actual condition of commercial usage of housing site in residential development complexes, and to derive effective development plan from now on by analyzing the influence of penetrating factors of commercial usage.

First, based on the features of land use caused by periodical changes of residential development complexes in Korea, I derived the features of land use and problems appearing in housing site of housing residential development complexes. And I also examined the theories concerning commercial use penetration of housing site in residential development complexes, and in addition, for studying the present situation of mixed use which occurs in a dwelling site, I inquired the penetration phenomenon of non-residential facilities in housing site, and derived the implication about factors influencing penetration.

Based on the derived factors influencing penetration, multiple regression analysis was used as a method for analyzing the influence on penetration ratio of commercial usage in housing site of residential development complexes. That means that as a dependent variable, penetration ratio of commercial usage by individual lot of housing site was selected, and as independent variables, characteristics of roads, characteristics of usage of environs and characteristics of the value of land were selected.

In case of independent variables, characteristics of roads were subdivided into condition of contact to the road, and the width of the roads, characteristics of usage of environs were subdivided into distance to commercial site, neighborhood facility, common housing site, schools, and parks, and finally, characteristics of the value of land were subdivided into official land price. I aimed to clarify the influence of factors of penetration causing commercial usage of housing site in 7 residential development complexes in Cheong-ju City through empirical analysis.

As a result of analysis, most factors seemed to influence on commercial usage of housing site, and major results by each characteristic are as follows. First, in case of the width of roads adjoining individual lots among characteristics of roads, it seemed that wider roads influenced on commercial use penetration more in Gagyeong 3 district and Sannam 3 district. Besides, in examining the influence of the number of roads adjoining individual lots directly, it showed to have influence in every district. This means that non-residential facilities tend to be located on regions where users' frequency of use is high, preferring regions having good accessibility of transportation.

Second, among characteristics of usage of environs, distance between single-detached residential units and common housing site had influence on the commercial use penetration in Sanman 2, Bunpyeong, Habokdae and Sannam 3 districts, distance between single-detached residential units and commercial site had influence in Sannam 2, Habokdae and Gagyeong 4 districts, distance between single-detached residential units and neighborhood facilities in Bunpyeong, Habokdae and Sanman 3 districts, distance between single-detached residential units and schools in Sannam 2 and Habokdae districts, and distance between single-detached residential units and parks in Bunpyeong, Habokdae and Sannam 3 districts.

Among these factors influencing commercial use penetration, distance to common housing, commercial site, neighborhood facilities, and school was analyzed to operate as a factor for the rise of penetration ratio of commercial usage when they are close to single-detached residential units. As opposite, in case of distance to parks, the more distant that is, the higher penetration ratio is. This means that detached houses are located close to parks which can be inferred to be a condition of pleasure environment, and to act as a factor preventing commercial use penetration.

Third, characteristics of the value of land showed its influence on commercial use penetration in Bunpyeong, Gagyeong 3, Habokdae and Sannam 3 districts. As a factor influencing commercial use penetration, official land price presents it a form of quality, and this is analyzed that the higher official land price is, the more it acts as a factor rising penetration ratio of commercial usage.
