Quality Incentive Mechanism Design of Construction Project: Quality Rank-Order Tournaments Model and Optimal Prizes Allocation in the Parallel Contracting Mode

In the parallel contracting mode with characteristics of single client and several contractors in construction phase, quality rank-order tournaments is analyzed whether it can incentive contractors to improve quality or not from the angle of client by applying the correlation theory and technique of Game theory and Economics of Information.
