Research Of The Relationship Between Construction Works Contract Compliance Monitoring System And Behavioral Strategies Based On Evolutionary Game Theory

In recent years, our country construction engineering contract performance regulation non-standard phenomenon more and more serious, contract execution rate is becoming more and more low, not only has a harmful effect on the owner, but also seriously affect the healthy and orderly development of construction and other industry, cause a series of social problems. All sorts of problems existing in the contract performance has become a "cancer" in the construction market, and even endanger the normal order of the construction market, must therefore be determined to root out. For this construction administrative departments at all levels and the relevant contract management department should be highly attention, on the ideological, organizational and mechanism. Take concrete and effective measures, to deal with various problems arising from the performance of the contract, well and truly establishing equal competition, normative and orderly construction market environment, and experts and scholars from all walks of life is in a heated discussion contract management strategy. Related research results show that the perfect performance regulation is valid contract for all kinds of changes in the process of project contract and claim risk a preview, but also guarantee the important means of the effective implementation of the contract management policy and measures. But different because of the interests of all parties in the process of construction claim and influence each other, make the regulation of contract performance have complex system and the dynamic characteristics of the change, the prediction and control of the regulatory long-term effects brought certain difficulties. It mainly with literature or from a technical point of contract management approach, or from the perspective of enterprise research reasonable contract performance supervision and decision-making methods, or from the Angle of construction administration department of the contract performance monitoring system strategy, etc., these studies to ease the construction engineering contract performance decisions and guide the construction enterprises have played a help, but the effect is not better. Therefore, this paper tries to use evolutionary game theory method to establish the system of project construction contract performance regulation behavior strategy in relation to the evolutionary game model to explore the performance contract mechanism and evolution trend of the regulatory system of the offender behavior, and thus to contract regulatory authorities and relevant person to put forward the corresponding control and management advice.Based on the construction administrative department and the contractors as analysis, the game relation between the main line, on this basis, through the evolution of thought and the combination of computer simulation method, coding system in operation under the different initial conditions of the language, to build the game subject analysis platform under different strategies, and specific analysis of the contract performance supervision system and the dynamic evolution process of the behavior person strategy, the control and management of the regulatory control strategy has carried on the corresponding optimization research.First of all, based on the rent-seeking theory, behavioral economics, institutional economics theory, project stakeholder theory, governance theory and game theory as the combing the two sides in the contract implementation supervision game system decision-making behavior mechanism of the basis of theoretical analysis and the research methods.Secondly, based on the limited rational premise is to build the construction engineering project in the contract performance regulation game system involved in both sides of the evolutionary game model, the replication dynamic equation on the basis of main to describe the game strategies between the two sides evolutionary stable condition and the change of the evolutionary stable strategy mode; Finally, the game theory in order to make the results more credibility, this article will through MATLAB numerical example and experiment analysis, combining theory analysis to verify different illegal benefit of default and default penalty policy and under the condition of different regulatory costs and regulatory benefits the existence of the game to participate in both sides of the evolutionary stable equilibrium.Again, and through the asymmetric the performance of the main regulatory system in the game analysis of the dynamic evolution process is pointed out that the degree of penalties set to the default behavior of the control function, analyzed the different degrees of punishment strategy control effect and different default illegal benefit, risk preference of the main game, as well as the supervision and regulatory costs for regulators to execute the contract only regulation is committed to strengthening improving the performance the influence degree of the supervision system, and obtained the contract performance the perfect degree of the supervision system and game participation behavior person strategy choice between the dynamic relationship between inconsistent conclusions, thus to obtain the direction of the construction project contract control management, and according to the results of theoretical analysis, puts forward the applicable performance regulation of rewards and punishment system; At the same time, through the dynamic analysis of the evolution game results of numerical experiments, proved reasonable and effective contract performance supervision system and appropriate penalties, project stakeholders behavior strategy will help the constraints and the regulator’s consciousness, improve the engineering construction contract execution rate and enterprise’s economic efficiency.
