Design for the Incentive System of Architecture Market

Architecture market is a typical dynamic game market with incomplete information, in which exists three principal parts who are proprietors, supervising companies and contractors. There is a complex principal-agent relationship among them. With the analysis of the principal-agent relationship among proprietors, supervising companies and contractors, two dynamic games of incomplete information have been established and analyzed. If the proprietor only pay instant fee to supervising company, the supervising company will take weak supervise. Only with appropriate incentive way, the strong supervise can be done. Based on it, an incentive system is established to make the supervising companies and contractors work hard, to realize the given purpose of the proprietors.
