建筑业是当今世界碳排放的重要来源，该研究领域受学界广泛关注。但是，较少有学者从利益相关者的角度对模块化集成建筑(Modular Integrated Construction，MiC)物化阶段碳排放影响因素展开研究。研究系统地考虑MiC物化阶段的碳排放影响因素，并形成利益相关者导向的影响因素清单;运用社会网络分析法构建影响因素网络模型，从整体和个体网络两个层面确定关键影响因素;对关键影响因素进行控制，从利益相关者的角度提出定向减排措施，并检测控制的效果。通过识别出的物化阶段的11个关键影响因素，研究对影响因素控制效果进行检测，显示定向减排措施可显著降低各影响因素之间的相互作用。通过探究MiC物化阶段碳排放影响因素的关联关系，可为利益相关者做相应的减排策略提供理论支持。
Stakeholder perspective on carbon emission factors in the materialization phase of modular integrated construction
Modular Integrated Construction(MiC)has been widely recognized as the mainstream building of the future.It is extremely important to investigate the factors influencing the carbon emissions of MiC.Implementing MiC in a project highly depends on a well-organized supply chain in which a variety of stakeholders participate.Therefore,this study investigates the carbon-influencing factors of MiC from the perspective of stakeholders.Seven categories of stakeholders and 44 carbon emission influencing factors in the materialization stage are screened to form a stakeholder-oriented carbon emission influencing factor list;a network model is constructed using Social Network Analysis(SNA),which is combined with a modular project case study to compare four metrics:overall network density,block model,point centrality,and intermediate centrality,respectively,to identify the key influencing factors at the level of the overall and individual networks;taking the intersection of the key influencing factors at the overall level and the key influencing factors at the level of the individual,to determine the core of key influencing factors,and the key influencing factors to control;targeted carbon emission reduction measures are proposed from the stakeholder perspective,and the control results are tested.The results identify 11 key influencing factors in the materialization stage,and carbon reduction recommendations are made for material suppliers,design units,module manufacturers,government,construction units,and construction units,respectively,with regard to the key impact factors.Finally,the control effects of the influencing factors are tested,and the test results show that the interaction forces between the influencing factors are significantly reduced.Through the study of carbon emission influencing factors in the building materialization stage of modular integration from the perspective of stakeholders,the correlations are explored to provide theoretical support for stakeholders to make corresponding emission reduction strategies.
