Abstract:Building energy service industry is an important part which promotes energy-efficiency renovation for existing buildings, but the current low quality of energy-efficiency service and serious shortage of demand hinder the development of ESCO who engages in energy efficiency service. Using evolutionary game theory, the paper establishes replicator dynamics model of ESCO and owner who participate in energy saving without government rewards and with government rewards, analyzes dynamic evolution of their behavior, and investigates the stability of the game results. The following conclusions can be drawn: the former incentives can promote energy-saving service bodies to actively participate in the energy-saving service market, the latter appropriate award can guide market players to improve quality of energy-saving service, in order to provide protection for healthy and orderly development for the market. At last, it is concluded on how to promote the development of ESCO.
