입낙찰제도의 효율적 운영은 건설산업의 발전과 산업구조 선진화를 위한 정부 정책의지 실현에 있어 핵심적인 요소가 된다. 본고에서는 현행 입낙찰제도 중 가장 큰 논란이 되고 있는 최저가낙찰제도를 대상으로 그 시행성과와 실태를 짚어보고, 그 개선방향과 효율적 운영방안을 제시하였다. 실태분석 결과, 현행 최저가낙찰제도의 핵심적인 문제는 지나친 저가낙찰로 인한 건설업체의 수익성 악화와 부실공사의 우려이며, 이는 건설업계의 차원을 넘어 국가와 공공의 이익에 있어서도 위험요소로 적용할 가능성이 크다. 그러나 건설산업의 선진화 관점에서 볼 때, 최저가낙찰제라는 제도 자체는 많은 긍정적인 가능성을 가지고 있는 제도이다. 따라서, 최저가낙찰제가 정착되기 위해서는 단기적으로는 실효성 있는 저가낙찰 방지대책의 조속한 수렵이 필요하며, 장기적으로는 최저가낙찰제가 제 기능을 발휘할 수 있도록 보증제도 개선, 발주자의 역량 강화 등 건설산업 전반에 걸친 제반 여건들을 정비해 나가야 할 것이다.

Our country's bidding system had made the lowest price successful bid system in foundation before introducing eligibility review system at July, 1995, and a averaged- price successful bid system or the restrictive-lowest price successful bid system had been enforced by repletion. However, they were introduced as dumping that do not reach in direct cost level of construction cost is generalized and worry about illegal construction practices rises by the lowest price successful bid system. According as they had not been promoted construction company's technical development effort or cost reduction effort, vicious circle that advocate competition principle again and recur as the lowest price successful bid system is repeated last 50 years. Therefore, I present improvement direction that can satisfy all Global Standard and real condition of our country through foreign countries example analysis to cope with the rapidly changing building circumstances socially and economically to correspond actively to the construction industry's reorganization to reconsider domestic construction engineering's competitive power.

In the construction industry government is not only an owner but also a consumer. Accordingly it should develop the construction industry and this role is important. Among them, the law of the ordering method is standards of selecting a successful bidder and have powerful influence over the construction industry and owners. Therefore this study said how the lowest bid method, which has taken effect still more, has influence on the construction industry and the public sector with the Causal Loop Diagram. According to analyzing this construction law, we can grasp the point of the strength and weakness of this law also examine a trend of how the present law is changed. While we studied, we tried to adhere to neutrality and form a new opinion about it because the previous studies were opposed to each other. As a result, to improve the relation between the government and private company, which were opposed to each other about arguments for and against the lowest bid method, this study suggest the method of making better the relation. The final goal of it is researching the inefficient factors and improving the weakness of this law.

The purpose of this study is to present both problems and improvement plans on the bidding system of the Korea National Housing Corporation, which orders apartment houses professionally. For data gathering, this study used data from electronic procurement system from 2001 to 2005. The research method of this study is to analyze the data categorized into four types: changes of ordering and contract price ration, the lowest-pricing bidding system, and permanent projects by grades. As a result of the analysis, the amount of ordering is biased in favor of particular level. Finally, this study present following improvement plans: 1) screening system and the lowest-pricing bidding system need to be supplemented, 2) the contract price ratio and the amount of ordering should be controlled, and 3) the improvement of PQ and the introduction of the list of Qualified companies by types need to be presented.

300억원 이상의 국가 및 공공기관 발주공사에 대해 최저가낙찰제를 대신하여 종합심사낙찰제 전면 실시 등의 내용을 담은 국가계약법 시행령이 개정되어 2016년 1월 1일부터 시행에 들어갔다. 종합심사낙찰제는 가격 뿐만 아니라 공사수행능력, 사회적책임을 종합 평가하여 낙찰자를 선정하는 제도로 기존의 최저가낙찰제에서 발생한 덤핑낙찰 및 이로 인한 잦은 계약변경, 부실시공, 저가하도급, 임금체불, 산업재해 증가 등의 문제점을 해소하기 위해 도입된 제도이다. 종합심사낙찰제 도입에 따라 공사 품질이 제고됨으로써 생애주기(lifecycle, 유지보수비용 등을 포함) 측면에서의 재정효율성 제고를 비롯하여 불공정 하도급 관행 개선 등 건설산업의 생태계 개선과 함께 시공결과에 책임짐으로써 기술경쟁 촉진 등 건설산업의 경쟁력 강화 효과도 기대된다. 또한 국가계약예규도 개정되어 주계약자관리방식에 의한 공동계약(주계약자 공동도급)이 최저가낙찰제에서 종합심사낙찰제로 전환됐다.

This study analyzed bidding data for construction projects ordered by the Public Procurement Service under the lowest bidding system since 2001 by using statistical technique in terms of construction types, company sizes, bidding prices. This study brings out construction company's bidding practices and problems caused by the current lowest bidding system and suggests the way to mitigate the problems and to improve the lowest bidding system. The analysis shows the problem of winning a bid in abnormally low price under the lowest bidding system, feared at the start, was realized. As bidding practice has polarized with low and high price, the analysis shows that the lowest bid system's market has a high possibility to be distorted by construction companies' bid strategies. To complement the lowest bidding system's problem, the analysis shows that introduction of the bidding system using particulars where bidders estimate construction quantities and unit prices by themselves is needed.

The government intensifies screening criteria for the guarantee of reasonable bidding price and the prevention of low bidding price, however, the low tender rate still becomes an issue. This study analyzed the problems of screening criteria for the guarantee of reasonable bidding price, and then derived some major issues such as the restriction of decisive factors for initial construction cost, the rate of activities over five percent of surveyed price and the restrictive review criteria of inadequate activities. To solve thess problems, this study suggests an improved process model for estimating optimal bidding rate that can select a contractor with the guarantee of reasonable bidding price.

In Korea, the first-price sealed bid auction and the constrained mean-price sealed bid auction(buchal-je in Korean) have been used alternatively as procurement auctions. In this paper, we characterize the constrained mean-price sealed bid auction in the context of mechanism design. We consider the general ?-bidder case in which each bidder has private information. Under the assumptions of uniformly distributed valuations and linear strategies, we derive the equilibrium of the constrained mean-price sealed bid auction. Furthermore, we analyze the efficiency and the expected revenue of this auction mechanism in comparison with the first-price sealed bid auction. Finally, we conclude with the critical remarks on the practical intention of the government which uses this auction.
