Simulation and Cooperative Mechanism of Construction Waste Disposal Based on Evolutionary Game
With the continuous advancement of urbanization,huge amounts of construction waste is generated in the large-scale construction activities,which has aggravated the problems of resources waste,environmental pollution and city appearance destruction.The effective disposal of construction waste can reduce environmental pollution and resource shortage,and promote the sustainable development of the construction industry.The bal-ance of interests among the participants in the disposal of construction waste is a key factor for effective disposal.Therefore,under the assumption of bounded rationality,it aims to improve the efficiency of construc-tion waste disposal from the perspective of interests,and clarify the roles and complex interest relationships of construction enterprises,the government and the public in construction waste disposal.Based on the evolution-ary game theory,the evolutionary game revenue matrix and evolutionary game tree are established,the replica-tion dynamic equation of each stakeholder is constructed,and the evolutionary stability strategy of the system is analyzed.The evolution path is simulated by Matlab,and the initial strategy and external variables of the system are simulated and analyzed combined with the system dynamics.The results show that when the benefits of active disposal by construction companies,the government,and the public are greater than the benefits or costs of passive disposal,each entity tends to actively disposal;construction companies are the generators of construction waste,so the government and the public should strengthen cooperation and actively supervise and guide them to legally dispose construction waste;penalties for construction companies,govern-ment subsidies,and active public participation can effectively promote the legal disposal of construction waste.The results can provide a theoretical reference for improving the efficiency of construction waste disposal and promoting the sustainable development of construction enterprises in China.
