Research On Passive Housing Project Incentive Mechanism

In the context of active search for effective ways to reduce energy consumption in buildings and active technological innovation,passive houses have become the best in sustainable development concepts in real estate construction projects because of their advantages of energy conservation,environmental protection,novel structure,and safety and comfort.The important development trend of practice and real estate construction technology change,however,because the development of passive residential projects has positive economic externalities,the government's effective incentive measures are an inevitable prerequisite for promoting better and faster development of passive residential projects.This paper starts from the interactive behaviors and decision-making choices of various stakeholders in the passive residential project,and analyzes the mechanism of the incentive mechanism of passive residential projects in China,the evolutionary game model of development incentive and consumption incentive with government as incentive subject,developer group and consumer group as incentive object was constructed.Based on the game results,the policy suggestions for improving the passive housing project incentive mechanism in China were proposed.First of all,we review the theoretical basis of the passive housing project incentive mechanism,and conclude that the improvement of passive housing project government incentive mechanism is the key to promote the development of passive residential projects,and the application of evolutionary game theory to design the incentive mechanism also has a greater advantage.Secondly,by analyzing the current status of China's passive residential housing development projects,we listed the problems in China's passive residential housing projects in terms of policies,technologies,and markets.Thirdly,based on the analysis of interaction behaviors and interests of government,developer groups,and consumer groups,from the perspectives of development incentives and consumer incentives,an evolutionary game with government as the main body,and model between developers and consumers as objects is established.Through the solution of the game model,the equilibrium state of the evolutionary game between the passive residential development system and the consumer system is analyzed to determine the scope of economic incentives for the government to take substantial incentive measures.Finally,based on the above discussion,it puts forward some suggestions for improving the incentive mechanism of passive residential projects in China.The government should give full play to its market guidance function.Based on the long-term resources,environment,and social benefits brought about by passive residential projects,it will play a leading role in the early development of passive residential projects.Appropriate material incentives for developer groups and consumer groups,balancing the benefits of developers and consumers,optimizing market supply and demand,Improve consumers'awareness of energy-saving concepts can effectively promote better and faster development of passive residential projects.
