An Empirical Analysis of the Relationship between Direct Construction Approach and Construction Quality in General Construction Companies

종합건설기업의 직접 시공과 건설 품질 사이의 관련성에 대한 실증분석

This study undertook a empirical analysis, delving into the association between the direct construction approach and the construction quality of general construction companies. The research hinged on corporate financial data to elucidate the premise that a reduced emphasis on direct construction approach by general construction companies correlates with a notable prevalence of building defects. Specifically, the analysis engaged with the top 100 construction companies based on their construction capability evaluation in 2022. This appraisal leveraged the Empirical Research Model(ERM) rooted in financial data-sets spanning 2017 to 2021. Findings underscored that as the ratio of direct construction approach diminishes, the incidence of building defects amplifies, signifying a consequential dip in construction quality. Moreover, the research reaffirmed that companies with elevated construction capability evaluations or larger organizational scales tend to register decreased defect rates. This study fortifies, from a theoretical perspective, the legislative imperatives championing direct construction approach, by empirically spotlighting the potential perils of over-reliance on subcontracting.

본 연구는 원도급 건설회사의 직접 시공 비중이 낮을수록 건축물의 하자를 유발하는 중요한 원인이 될 수 있다는 점에 대하여 2017년에서 2021년까지 기업 재무 데이터를 바탕으로 실증분석모형(ERM, Empirical Research Model)을 이용해 검증하였다. 그 결과 직접 시공 비중이 낮을수록 건설 품질을 저하시키는 주요 원인이 된다는 점을 확인하였고, 본 연구는 건설품질을 높이기 위해서 직접 시공 의무를 강화해야 한다는 주장을 이론적으로 뒷받침하는 실증분석이라는 점에서 그 의미을 가진다.
