工程项目交易方式生产效率比较研究

摘要

From the perspective of project production efficiency, a project production efficiency index system was built up, and the corresponding project production frontier of the project delivery systems (PDSs) was also established. Design-bid-build(DBB) and design-build (DB) delivery system were compared by employing production frontier and data envelopment analysis method. The comparison results show that DBB delivery method has advantages in duration, while DB has advantages in cost. The inner mechanism was further explored, which provided a scientific decision- making support for owners' PDS selection practice.%从工程项目生产效率的视角,应用生产前沿面与数据包络分析方法,建立了工程项目交易方式生产效率指标体系,构造了工程项目交易方式生产前沿面,对设计/招标/建造(DBB)与设计/建造(DB)进行比较.通过比较生产效率相对最优的DBB与DB项目,得出DBB方式在成本方面更有优势,而DB方式在工期方面更有优势,并分析了得出这种结果的内在机理,从而为业主科学地进行工程项目交易方式选择决策提供了支持.
