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.

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.

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.

정부는 지난 8월 11일 건설분야 기업환경 개선대책을 확정 발표했다. 정부가 발표한 '건설업 기업환경 개선대책'에 따르면 앞으로 최저가낙찰제 공사의 덤핑입찰을 차단하기 위해 노무비와 품질 안전 환경 등의 공종에 대한 저가심의가 한층 강화되고, 하도급대금 지급 확인제도를 모든 공사에 확대 적용하며, 주 계약자 공동도급제도도 개선한다. 또한 중소 지역업체의 경영환경 개선을 위해 건설공사 도급하한액을 상향 조정하고 입찰참가자격 사전심사 시 지역업체 시공참여 배점제를 도입한다.
