Research On Economic Incentives For Energy-Efficiency Renovation For Existing Residential Buildings In Northern Heating Areas

Because the energy consumption was high, heating systems was inefficient and residential thermal was poor, it was very necessary to implement energy-efficient renovation(ER) for existing residential buildings(ERB) in northern heating areas( NHA ) in China. However, the imperfection of energy-efficient market mechanisms(EMM) and the lack of encomic incentives(EI), the implementation of energy-efficient renovation for existing residential buildings(ERERB) was slow. Based on how to promote ERERB effectively, selected EI for ERERB as the research object. Through a wide range survy of ERERB, utilize the knowledge of Walras general equibrium theory, Pareto optimality theory, non-equibrium theory, externality theory, game theory and behaviour ecnomics. Deeply research on the excellence of energy-efficient market mechanisms of ERERB, non-equilibrium stir harm of ERERB, externalities ifflunce of ERERB, and design EI for ERERB.Acorrding to the chaotic situation of the content of ERERB, divided ERERB to two parts by system engineering: one was engineering systems which included buildings envelope renovation, measurement of indoor thermal heating system and transformation temperature control; the other part was institution system which included hot commercialization and socialization, heating price linkage mechanism, urban heating franchise. And then the administrative divisions, thermal zoning, transform content, heating the form of transformation system were defineted, which would provide microecomics and macroecomics properties to study energy-efficient renovation for existing residential buildings, and give foundation to analize the market equibrium and market failures of ERERB.Secondly, through the establishment of Walras equilibrium model and Pareto optimal model for ERERB, proved the existence, uniqueness and optimization of Walras equilibrium in ERERB. In an ideal status, market mechanism was the most efficient way of resources allocation for ERERB.Thirdly, established fixed price model and external model for ERERB, analyzed the impact of non-equlibrium operation for heating market of ERERB, and the harm of externalities on the field of implementation of social welfare maximization in ERERB. Government need to promote the development of ERERB by pushing the heating mechanism reform forward and formulating scientific economic incentive programs.Fourthly, on the basis of studying the EI experiences of Germany and Ploland, established dynamic game model between government departments and heating enterprises, economic behaviour model of heating consumers. Government deparments should be the main incentives, the incentive target would establish market mechanisms for ERERB, heating consumers and enterprises should be the incentive objects, the incentive model would be"carrot, stick and public education". Using the theory of market life cycle of ERERB, designed the corresponding EI from the start-up, growth and maturity stages of energy-efficient market.Lastly, according to the following research contents accomplished the empirical research of EI for ERERB. From the status of ERB in Beijing and its growth trend, the energy consumption status of ERB in Beijing and its trend, the energy-efficiency trend of ERERB in Beijing, demonstrated the implementation necessity of ERERB in Beijing. On the basis of analysizing the achivements and problems of ERERB in Beijing during eleventh five-years, analysized the the imfluence of market failure for ERERB in Beijing, demonstrated the necessity of EI in promoting ERERB in Beijing. On the basis of analyzing the progress and problems of economic incentive for energy-efficient renovation for existing residential buildings in Beijing, proposed corresponding suggestions from six parts, which included establishing special funds for energy-efficient renovation for existing residential buildings, definiting the contents of energy-efficient renovation for existing residential buildings, strengthending the economic incentive to energy-efficient material and products, fostering energy-efficient renovation for existing residential buildings market, pushing the heating mechanism reform forward furtherly, improving the support measures of energy-efficient renovation for existing residential buildings.Government should implement economic incentive policies for energy-efficient renovation for existing residential buildings by reducing the heating consumers'barriers to enter energy-efficient renovation for existing residential buildings and strengthening the heating enterprises'determination to implement energy-efficient renovation for existing residential buildings.
