Evolutionary Game Analysis Of Stakeholders In Urban Ecological Risk Management And Control

Urban ecosystem is a complex artificial system composed of nature,economy,society and culture,as well as some biological and abiotic elements.In recent years,with the rapid and rapid development of China's economy,the living standard of the people has been greatly improved,but the growth of the economy is often accompanied by the unreasonable and extensive pattern of production structure,which lead to the deterioration of the ecological environment.Because of the large number of people involved in the urban ecosystem,many stakeholders should be involved in the process of urban ecological risk control.Under the premise of rational,each subject will adjust its own behavior strategy through each other's behavior strategy,thus realizing its own optimal strategy and eventually to a stable state.First of all,this paper introduces the relevant theoretical contents of evolutionary game,analyzes the characteristics of evolutionary game theory and the relationship between evolutionary game theory and classic game theory.Secondly,it introduces the connotation and characteristics of ecological risk and the relationship between urban ecosystem and urbanization.Finally,through the analysis of the stakeholders of the stakeholders of the ecosystem,the government,the enterprises and the public are defined as three major related subjects,and the game behavior between the three parties is analyzed and the two evolutionary game income matrices of the government and the enterprises,the government and the public are constructed by combining the related knowledge of the evolutionary game,and the construction of the income matrix is constructed by the construction of the government and the government and the public.The dynamic equation is replicated and the equilibrium point is obtained and the stability analysis is carried out.The main cost factors among the stakeholders are simulated and analyzed.According to the result of the evolutionary game,the government encourages the enterprises and the public to actively participate in the urban ecological risk management and control.
