建筑节能改造项目风险共担具有耗散结构特性,基于对风险共担的系统解析,利用耗散结构理论,探讨既有建筑节能改造项目风险共担耗散结构的形成机理.在此基础上,构建了基于灰关联熵的风险共担结构演化方向判别模型,指出了风险共担结构的3种演化方向.最后,针对研究结果从推进协同治理、强化制度建设、合理设计契约3个方面提出建筑节能改造项目风险共担决策优化建议.
Risk sharing structure in the existing reconstruction projects for building efficiency the characteristics of dissipative structure.The analysis of the risk sharing structure and the dissipative structure theory are applied for investigation of the formation mechanism of the risk sharing dissipative structure in the reconstruction project for building energy efficiency.On this basis,the direction discrimination model of risk sharing structure is constructed based on the grey relational entropy evolution model,and 3kinds of evolution direction of risk sharing structure are presented.Lastly,suggestions for promoting collaborative governance,strengthening regulation,and designing contract are proposed.
