This paper considers the effect of various types of procurement auction system on competition focusing on the rate of successful bidding. We analyze the number of bidders and the rate of successful bids using online procurement data of the Public Procurement Service. The average number of bidders is 301 and the average rate of successful bids is 87.42% while the weighted average rate is 75.13%. These numbers show that there is quite strong competition among bidders and the rate is lower as the expected price is higher. When we analyze the data of price procurement auction, the rate is also shown to be lower as the expected price is higher. Furthermore, the rate decreases as the number of bidders increases which naturally makes the competition stronger. Meanwhile, the analysis finds that the inclusion of the onsite bidding, the PQ(Pre-Qualification) result, or major-10 winning companies cannot explain the rate much in our data. In case of turnkey-alternative, the average rate of successful bidding for 484 cases record 90.20%. The average is 84.89% with 120 alternatives and 91.97% with 364 cases of turnkey. The reason why the rate of turnkey-alternative is lower than that of price procurement auction is the lack of competition as well as the systematic difference. By setting up a model, we are able to explain the difference in rate caused by the respective reason. When we suppose there are 3 bidders in case of price procurement auction for a project that exceeds 100 billion won, the rate is expected to be around 64%. This implies that difference of 26% is caused by the systemic difference and 3% by the lack of competition. Therefore, we conclude that the difference in rate between turnkey-alternative and price procurement auction is caused mainly by the systemic difference. In case of PPP(Public Private Partnership) projects, among 154 projects in total, only 40% has more than 2 bidders that compete. The average number of bidders is 1.88 which is less than 2, and the average rate of successful bids is 90%. In sum, under the price procurement auction, there is strong competition which is reflected by the rate of successful bids. However, there is room to decrease the rate by strengthening the competition under the turnkey-alternative. Also with PPP projects, we expect the rate can be steadily reduced with revived competition among bidders.

Earnings of domestic enterprises are expected a serious damage because the lowest cost bid system and the current cost estimate system. In 2005 average successful bid rate for the lowest cost bid project is below 60%, this is not reach at the operating budget of enterprise. Many problems such as illegal construction, low price subcontract, chain enterprise loss com in to practice because of low successful bid rate. In addition earnings of the enterprises expected to be the minimum, because of enlarge execution of the current cost estimate system. This study tries to lend assistance by giving alternative for the construction enterprise by presenting the bid system, investigate and compare foreign system with domestic and analyze correlation of the lowest cost bid and the current cost estimate system.

지방계약법 시행령 개정을 통해 공사 분야의 최저가낙찰제가 과도한 가격경쟁을 유발함에 따라 300억원 이상인 공사입찰의 경우 국제표준에 맞게 시공실적, 기술능력, 시공품질 등을 종합적으로 고려하여 낙찰자를 선정하는 종합평가낙찰제로 전환하고, 지방재정 조기집행 활성화를 위하여 계약이행 대가의 지급기간을 단축했다. 또한 지방계약예규 개정을 통해 주계약자공동도급 시 주계약자가 선금 수령일로부터 5일 이내에 부계약자에게 지급토록 하였다.

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.

This paper re-evaluated the research on the accounting information's effectiveness in military construction contracts, questioning the former research results on the central army's construction contract that was under the Qualification Assessment System, especially concerning the relations between the accounting information and the bidding ratios as well as the relations between the bidding rates and the defect rates, which targeted between 1 to 10 billions civil engineering, construction, electricity, telecommunication, and environment work types. Unlike the previous results, the relationship between the accounting information and the bidding rates was shown to be considerably limited that the bidding ratio could not be identified through the accounting information, while it could discern the relations with the defect rates. Furthermore, the proven results did not support the hypothesis that the differences in bidding rates could affect the defect ratio. However, through the prediction model of bidding and defect ratios, we could identity the accounting variables that influenced the ratios. Additionally through the results regarding the non-financial indexes in the Pre-Qualification items, the weight on these indexes could be adjusted. In conclusion, the research results has given us new understanding of the problems in the Qualification Assessment System which accounts for the majority of the current military construction contracts and provide validity on the government's expanded implementation of the Lowest Price Award System.

기획재정부와 행정안전부는 계약 예규를 개정하고 지난 4월 2일부터 시행에 들어갔다. 기획재정부는 이번 계약예규 개정을 통해 등록기간 3년 미만 업체가 공동수급제에 참여할 경우 만점기준을 완화했고, 1억 이상 3억 미만 전문공사의 경우 만점기준이 발주금액에 대한 '3년 실적의 1/2배 이상'에서 '평가면제'로, 3억 이상 50억 미만 전문공사의 경우 '3년 실적의 2배 이상'에서 '1/2배 이상'으로 평가방법을 완화했다. 또한 발주기관에서 공공공사 예정가격을 산정할 경우 반드시 최신 표준품셈을 사용하도록 의무화했으며, 적정 노무비 보장 심사 강화 방안으로, 최저가낙찰제 공사에서 업체가 제출한 노무비가 발주기관에서 산정한 노무비의 80% 미만일 경우 탈락된다. 기획재정부는 이번 개정으로 시공경험이 부족하지만 기술력 등이 우수한 신설 중소 업체가 공공공사에 참여할 수 있는 기회가 늘어날 것으로 기대하고 있으며, 최저가낙찰 시 과다한 노무비 삭감 등으로 인한 건설 근로자 소득감소 및 내국인 건설업 기피 등을 막을 수 있을 것으로 기대하고 있다. 한편 행정안전부는 이번 계약예규 개정을 통해 지방자치단체 입찰 및 계약관련 예규를 현행 11개에서 2개로 통합했고, 지자체가 발주하는 50억원 이상~100억원 미만의 공사의 경우 참가자격 적격심사 항목 중 자산회전율 평가를 삭제했으며, 신용평가 등급을 완화해 지방 중소기업들의 입찰 참가 기회를 확대하기로 했다.
