Research On Mechanism Of Urben Residential Buildings Carbon Trading Based On Evolutionary Game

With implemention of carbon peak and carbon neutral strategy in China,it’s imperative to effectively reduce carbon emission in the construction sector.As a new model of urban residential buildings energy conservation,urban residential buildings carbon trading plays an important role for achieving the strategy of "carbon peak and carbon neutral" and reducing carbon emissions from buildings in China.Seen from refering to cueerent trading mechanism of public building,it sould be faced difficulties to carry out urban residential buildings carbon trading,such as high transaction costs and complicated procedures referring to the current carbon trading mechanism for public buildings,and which is not effectual depend on spontaneous market mechanism.Therefore,the cooperation among the government,property service enterprises and owners of urban residential buildings is necessary.By use of evolutionary game theory and symbiotic theory,this paper researched appeal of all parties among government and property companies and users base on overall consideration,and established solveing way of residential building carbon trading of efficiently cooperation among three parties.The main research contents and conclusions were showed as follow:Firstly,this paper constructs an evolutionary game model of participants in carbon trading of urban residential buildings,discusses the evolutionary and stable strategies of the government,property service enterprises and owners of urban residential buildings based on the analysis of interest demands of participants in carbon trading of urban residential buildings,and the simulation analysis is carried out.The research showed that government should encourage property service enterprises and urben residential building owners to participate in carbon emission trading and guide them to establish a cooperative mechanism.Property service enterprises and urben residential building owners should participate in carbon emission trading actively and fulfill their social responsibilities while pursuing economic benefits,revenues of both sides were increasing and tending to stabilization in urban residential building carbon trading.The marginal rate of return brought by government incentive policy will decrease gradually with the increase of subsidy amount.Secondly,the Lotka Volterra model for carbon trading of urban residential buildings with three parties and "property-owner" is constructed based on symbiosis theory.This paper analyzes the symbiotic stability points and conditions of the three main bodies of carbon trading for urban residential buildings,and summarizes the evolution of different symbiotic modes between property and owners,and conducts simulation analysis.The research shows that the marginal return rate of government incentive policies will gradually decline with the development of carbon trading for urban residential buildings,and the benefits of improving ecological environment and enhancing public credibility will gradually approach the maximum value.The income growth rate of the owners and the property will gradually decrease due to the restriction of carbon emission reduction cost and carbon price,and the income of both sides will gradually approach the maximum value.The "property-owner" symbiotic system eventually evolved into a mutualistic symbiosis stage,and formed a consortium of "benefit sharing and risk sharing".In the end,carbon trading mechanism of urban residential buildings is designed.The mechanism coordinates the interest demands of the government,property service enterprises and urban residential building owners in terms of total carbon emission control,carbon emission allocation calculation,operation process,transaction supervision,incentive and constraint,so as to promote the formation of long-term stable cooperative relations among the three parties.In the background of carbon peak and carbon neutral strategy in China,the research could be effective on support of theory of carrying out urban residential buildings carbon trading.
