摘要

There are a lot of collusion actions of parties interested as the bidders,the tender agent and construction organization in construction project bidding.Those actions seriously destroy bidding equity and science,infringe the investor interests and impact on the efficiency of the investment decision-making process of construction project.This paper adopts contract theory,principal-agent theory and auction theory to probes into the internal mechanism of collusion resulted from information asymmetry,incentive unbalance of contract mechanism,survival pressure of competition-in-no-order and rent-seeking and the external environment of collusion given cause for lack of contract integrity,faults of market supervising system and imperfect property rights system reform.This research proposes that the countermeasures of bidding collusion should proceed from both internal mechanism administration and external environment improvement,namely,sets up incentive-constraint,integrity-liability investigation,peer-review and reputation punishment mechanisms to keep away the collusion actions,cultivates construction enterprise fair competition and integrity consciousness,and unceasingly improves market supervision mechanism to administrate external environment.In our research,we intend to probe into the measures and thoughts to prevent collusion actions in the bidding and enhance the efficiency of construction project investment control.
