绿色建筑项目具有增量成本高、施工难度大、地域差异性明显等风险特性。本研究以总承包商视角，提出EPC模式下绿色建筑项目链式风险管理框架。首先，通过大量的文献研究与专家访谈，识别EPC模式下绿色建筑项目在实施过程中的风险源、风险事件与风险结果；其次，初步构建风险链；通过发放和收集223份有效问卷，利用结构方程模型探究各个风险要素之间的因果关系，寻找关键风险链；最后在此基础上，分别提出设计、采购、施工阶段的风险控制建议。研究可为EPC总承包商有效进行绿色建筑项目风险管理提供参考，以确保质量、成本、进度等目标的实现。

Green building projects have risk characteristics such as high incremental cost, high construction difficulty, regional differences and so on. Based on the perspective of general contractors, this research proposes a chain risk management framework for green building projects under the EPC model. First, through a large number of literature studies and expert interviews, identify the risk sources, risk events, and risk results during the implementation of the green building project. Then, make a preliminary judgment to build risk chains. Next, through the issuance and collection of 223 valid questionnaires, use the Structural Equation Model (SEM) to explore the causal relationship between various risk indicators and find the key risk chains. Finally, the risk management suggestion at design, procurement, and construction stage are put forward. This research provides EPC general contractors with effective risk management of green building projects to ensure the realization of quality, cost, schedule and other goals.
