Resumen
With the continuous advancement of urbanization, a huge amount of construction waste is generated in large-scale construction activities, which has aggravated the problems of environmental pollution, waste of resources and destruction of city appearance. Construction waste recycling can effectively solve these problems. However, the recycling rate of construction waste is low in China. Therefore, this paper, firstly through the way of literature analysis and questionnaire investigation, analyzes the factors that influence construction waste resource utilization, determines the key influence factors and the stakeholders in the process of construction waste resource utilization, and uses social network analysis method to identify core stakeholders. On this basis, this paper selects construction enterprises and recycling enterprises as the game subjects, and the government and the public as the external environment to explore the influence of the external environment on the cooperation behavior of the two stakeholders, and uses Matlab simulation to analyze the influence of external variables on the decision-making behavior evolution of the two stakeholders. The research results show that the government, construction enterprises, recycling enterprises and the public are the four core stakeholders of the construction waste recycling system, which have the power to control the information transmission among other stakeholders and play a great supporting role in the smooth implementation of the construction waste recycling project. Among them, the construction enterprise and recycling enterprise are the construction waste recycling system?s two stakeholders playing the pivotal role, and the government and the public are the external environment of the construction waste recycling system?s incentive and regulatory effect. The difference between the benefits and costs of the two stakeholders and the effect intensity of the external environment determines the stable state of the system, that is, the stronger the effect of the external environment and the larger the difference, the more the behavior of the two tends toward the recycling, on-site recycling strategy. Government penalties and rewards can effectively reduce the illegal dumping of construction waste, while excessive penalties and rewards have limitations in controlling illegal dumping. Public participation can effectively improve the efficiency of government supervision. The research results help to deeply understand the behavior, needs and cooperation of stakeholders in the construction waste recycling market, improve the efficiency of cooperation between construction enterprises and recycling enterprises, and provide management inspiration for the construction waste recycling practice.
