公共工事の入札制度に関す る一考察

Japan’s tendering system for public works is now under pressure to change both domestically and internationally due to the detection of bid rigging and demands for internationalization. After clarifying the characteristics of Japan’s tendering system and the deficiencies in the public procurement system, this study emphasized the three values of Japanese people: (a) Thoughts of harmony, (b) Eat until you’re 80% full and Understand each other without talking, and (c) Focus on trust, proposed a new tendering system from the perspective of “what kind of system would be suitable for building a better Japan?” and analyzed its appropriateness. The framework of the system, which was built by emphasizing three Japanese values, is: (1) The nomination system is the basic framework, and the nomination criteria are made objective and publicized, (2) Discussions for determining the winner are authorized, and general competitive bidding system is used together, (3) Announcement of the ceiling price, (4) Introduction of the Value Engineering (VE) system before and after the contract, and (5) Continuation of the construction completion guarantor system and advance payment system. It seems that some aspects do not necessarily meet the current social demands. Finally, we summarized future issues of improving the tendering system.
