Research On The Subject Behavior Of Agent Construction System Of Non-Profit Government Invested Projects By The Evolutionary Game

Along with the progress of the society and the vigorously promote of urbanization,non-profit government invested projects gradually get the attention of the governments at all levels.Agent construction system arises at the historic moment to improve the management capacity on non-profit government invested projects better,and overcome the abuse of the quaternity of “investment,construction,management,use” in the traditional management system.The implementation of the agent construction system solved some previous problems like estimation exceeding budget,budget exceeding financial estimation and final accounts exceeding budget and the wasting of resources in non-profit government invested projects.But the introduction of a new subject caused the following problems: collusion with contractors and managerial slack inundate in construction units of lucrative purpose,and thus damage the interests of government departments as the delegate.Therefore,make a deep analysis of the drivers of interests and the behavior evolution path of the interests of parties in the project of the agent construction units during the implementation of the related project,and it has some guiding function for government departments to formulate the corresponding system and strategies to standardize the behavior of agent construction units and contractors.Paper based on evolutionary game theory and system dynamics method,explain in economics and the evolution simulation of the behavior of the main part in the non-profit government invested projects.First of all,through literature research and the study of related theory,combing the results of international relevant research and practical experience of the agent construction system of the non-profit government invested projects,evolutionary game theory,system dynamics methods etc.Then,on the basis of clarifying the mutual relations among the government departments,agent construction units and contractors,the paper built the tripartite game payoff matrix and worked out the evolutionary stable strategy.What is more,the paper construct a simulation model by using system dynamics,which is use for analyzing the variation of subject strategy choice as the pay parameters change.Finally,put forward to the related policy and suggestions to help the government departments to standardize the behavior of agent construction units and the contractors.Simulation results show that: in order to promote agent construction system steadily,the governments should focus on raising the level of government regulation,increasing construction agent unit and the contractor’s reputation cost,and improving the reputation mechanism and assessment mechanism.The study of this paper not only improves the agent construction system and game theory,but also plays a role in promoting the agent management level for non-profit government invested projects.At the same time,the paper should be of great practical significance.
