中文摘要：

既有建筑节能改造是建筑节能的重要组成部分,主体行为是既有建筑节能改造成功的关键。本文在对既有建筑节能改造市场正外部性、信息不对称性以及动力乏失等特征进行分析的基础上,构建了业主间博弈模型,可知通过采取激励约束政策可以转移信息不对称性下业主的最优策略。而后,通过分析业主在市场信息获取中的＂单向行车道＂问题,提出了解决信息不对称性下业主逆向选择的对策。最后,运用经济学理论分析了业主在市场供给—需求下动力乏失的原因,并给出了相应对策。

Energy-saving retrofit of existing buildings is an important component of building energy efficiency,and the owners＇ behavior is the key issue.In this paper,based on the analysis of positive external feature,information asymmetry and impetus lacking in energy-saving retrofit market of existing buildings,the game analysis model among owners was established.It was illustrated that the optimal strategy among owners could be diverted by taking incentive and restraint policies.And then,by analyzing the problem of single lane for obtaining the market information of owner,the countermeasures to solve owners＇ adverse selection were put forward.Finally,the reasons of impetus lacking under market supply-demand condition were discussed applying economics theory,and the corresponding strategies were presented.
