Abstract

To estimate collusion effects on bid award in Public Construction works, this paper uses Logit Model, which is a choice variable model. Price, design, competition, and other factors are included, with a special focus on collusion, as independent variables in the model. The empirical results are as follows. First, collusion has little effects on bid award, but great impacts on bidding behavior. Secondly, the score of design is the most important and significant factors among all variables. Thirdly, competition has also significant effects on bid award. Finally it is analyzed that institutional framework and characteristics of public work have some effects on bidding award.

본 연구에서는 기본적으로 로짓모형, 즉 선택변수 모형을 사용하여 가격, 기술점수는 물론 담합여부, 경쟁정도, 제도적 요인, 공사의 특성 등이 공공공사 낙찰에 영향을 미치는지를 분석하였다. 특히 최근 논란이 되고 있는 담합여부가 낙찰에 미치는 부분에 주목하였다. 본 연구의 주요 실증결과와 시사점은 다음과 같다. 먼저 담합은 낙찰에 직접적인 영향은 미미하지만, 담합 및 비담합의 경우에 따라 입찰행태에 영향을 주는 것으로 나타났다. 두 번째로 낙찰에 영향을 주는 변수 중 설계가 계수 상으로는 가장 중요하고 유의한 요인으로 나타났다. 세 번째로 입찰참가자수로 측정된 경쟁의 정도도 낙찰에 중요한 역할을 하는 것으로 나타났다. 마지막으로 제도적 요인과 공사 특성에 따라 가격, 설계점수, 담합, 경쟁정도의 영향이 다르게 나타나, 이들도 입찰에 영향을 미치는 것으로 분석되었다.
