| In recent years,the government puts a large amount of resources in public infrastructure projects,in order to Improve economic development of science,education,culture,health,body and other undertakings.In the process of government investment projects,all kinds of complexity project risks are existence,so it should be used to divert the project risks by the project insurance.Because of the information owned by the construction units is asymmetric from that by the contractor,the contractor may choose to make use of asymmetric information to not buy,buy less,or buy back first behaviors in the project insurance to pursue its benefits,which would be harmful to the government investment projects once the risks happened.On the contractor’s attitude of the government investment projects,the author has studied many domestic and foreign researches and papers,under the direction of supply chain theory,management theory,economic theory,the evolutionary game theory is adopted to analyze the strategies of evolutionary equilibrium within three states: punishment mechanism in long term cooperation and no punishment mechanism in long term cooperation.Analyze and compared with the results,punishment mechanism is not able to effectively inhibiting the contractor’s opportunistic behaviors,so,construction units and contractors should be fully communicate and gradually establish system management network,at the same time,it should be establish an improved and standardized project insurance purchase facility、Internal management mechanism、Performance evaluation system to Increase the contractor’s potential value of long-term cooperation,in order to achieve mutual and win-win benefit.The innovation of this dissertation is applying evolutionary game theory to inhibiting contractor’s opportunistic behaviors in government investment projects.This paper has built evolutionary game models in two states,compared with the results and achieved the conclusions. |
