Abstract

This study was conducted to analyze the actual utilization rate of the deposit for defect repair of apartment complexes and its influential factors. We analyzed the data on enforced defect deposit cases by using one-sample t-test, Pearson's correlation analysis, and simple linear regression analysis. The difference between the deposit amount specified and the enforcement amount actually disbursed was found to about 0.51%. The change rates for short-term costs amounted approximately to $839KRW/m^2$ and 130,000 KRW/household per year, and those for long-term costs were $647KRW/m^2$ and 123,207 KRW/household per year. The results warrant the need for further research on establishing a deposit amount based on actual statistical data.

본 연구는 하자보수보증금의 실제 사용 비율과 이에 영향을 미치는 요인들에 대하여 분석하였다. 분석을 위해 실제 집행된 하자보수보증금의 자료를 수집하여 분석하였다. 분석은 일표본 t검정, 피어슨의 상관분석, 단순선형회귀분석을 통해 이루어졌다. 그 결과 단기하자보수보증금의 예치금 규정은 실제 집행금액과 0.51% 정도의 차이를 보이는 것으로 나타났다. 단기비용의 변화율은 약 839(원/$m^2{\cdot}$년), 약 130,000(원/세대${\cdot}$년)이고, 장기비용의 변화율은 약 647(원/$m^2{\cdot}$년), 약 123,207(원/세대${\cdot}$년)인 것으로 나타났다. 본 연구 결과는 예치금 설정과 관련하여 실제 통계자료 기반의 추가 연구가 필요함을 보여준다.
