摘　　要：厘清装配式建筑的增量成本和增量效益问题,对促进装配式建筑的发展十分重要。从全寿命周期的角度分析装配式建筑项目在决策、设计、生产、运输、施工、运营回收等阶段的增量成本及增量效益构成,并以P装配式建筑项目为例进行实证分析。结果表明:增量成本主要出现在设计阶段和施工阶段,增量收益主要体现为用工减少及工期缩短所带来的经济效益,实证案例的增量效益大于增量成本,表明装配式建筑具备可行性和推广性。Clarifying the incremental costs and benefits of prefabricated buildings is crucial for the development of prefabricated buildings.From the perspective of the entire lifecycle,the article analyzes the incremental costs and benefits of prefabricated projects in the stages of decision-making,design,production,transportation,construction,operation,and recycling.And takes the P assembly project as an example for empirical analysis.The results indicate that incremental costs mainly occur in the design and construction stages,and incremental benefits are mainly comes from the economic benefits brought about by reduced labor and shortened construction periods.The benefits of prefabricated projects is higher than incremental cost in the examle,demonstrates the feasibility and popularization of prefabricated building.
