Study On Incentive Mechanism Of Smart Building Market Based On Evolutionary Game Theory

In recent years,the rapid development of urbanization in China has led to a rapid expansion of urban population,which caused many problems such as resource shortage,environmental pollution,traffic congestion and so on.Based on the development of new information technology such as Internet of things and BIM,and the popularization of intelligence,smart city as a new mode of city urbanization is emerged.Smart building,the basic element of smart city,is of great significance for realizing scientific governance and promoting sustainable development of cities.However,smart building market in our country is still in the initial stage of development.The characteristics of smart building such as high technical cost,long return cycle and positive externalities,which prevent the market development.Therefore,it is crucial to coordinate the interest contradictions of main stakeholders of the smart building market and formulate appropriate incentive mechanisms to promote the sustained and healthy development of smart building market.First,by analyzing the development status and existing problems of the smart building market,the main stakeholders are defined.Based on the analysis of the behaviors of various stakeholders,a replicated dynamic analytical method is used to research the game relationship among main stakeholders of smart building project,including government,developers and the public.Secondly,two-party and tripartite evolutionary game model are established.By solving Jacobian matrix,evolutionary equilibrium solutions under different initial conditions are derived.Then software Matlab is used to simulate the evolutionary path of the two and three parties to verify the correctness of the theoretical analysis.By analyzing influence on tripartite evolutionary stable strategies by variation of different parameters,the main factors are found out.In the end,the incentive framework of smart building market is constructed,incentive policies are designed,and implementation of incentive policies and safeguard measures are proposed.In the framework of evolutionary game theory,the research on the incentive mechanism of smart building market has enriched the related theory and method of incentive mechanism in smart building market.The study clarified the key role of the government in the development of the smart building market,which has a certain practical reference value for guiding government incentives.
