Research On Project Risk Management Based On The Theory Of Information Asymmetries

Global economic growth,technology-progress,Economy structural revulsion and market competitive severity brings with it great increase in the uncertain factors,risk and risk loss of projects.From the point of view of information economics,Information asymmetries places a premium on the opportunism behavior,namely adverse selection and moral hazard is the primary cause of breaking faith in the construction market and the essential cause of brings project risk.So it is feasibility and important significance to the application of information asymmetries theory in project risk management.The research work done by the author was illustrated as below:1,The ecumenical theory of information asymmetries and project risk.The dissertation introduces incomplete information and asymmetric information, and it analyses the form of expression & characteristic of information asymmetries.The dissertation introduces the essential content of information asymmetries and analyses the connection of information asymmetries and project risk.And it studies information asymmetries of project management based on the information model of project management. Multi-dimensions structure,a descriptive method of project risk is put forward. And it sets up risk measurement function of project risk under information asymmetries.2,The behavior risk of project main body. The dissertation puts forward the concept of the behavior risk of project main body and discusses the importance of studying the behavior risk of project main body based on the relaionship of information asymmetries and the behavior risk of project main body.It founds the evaluation index system of the behavior risk of project main body. And fuzzy comprehensive evaluation and BP artificial neural networks have been used to evaluate the behavior risk of project main body and a practice example has been analyzed. The dissertation introduces the relaionship of risk effect balance and risk attitude based on the risk effect mechanism and the utility theory.3,The behavior game of project main body under the circumstance of asymmetric information.Firstly, the dissertation analyses the game of bidding, fulfilling between owner and contractor.Secondly, it analyses the game between owner and supervisor, contractor and supervisor.Thirdly,it founds the behavior game model among principal parts of general project and government invest project based on two-person game , and...
