EPC模式下基于回购契约的建筑供应链采购协调模型研究

Research on Purchasing Coordination Model of Construction Supply Chain Based on Repurchase Contract under EPC Mode

摘要: EPC项目作为当前建筑行业的热点问题，如何保障其绩效和质量受到了广泛关注。本文以EPC项目建筑供应链中的采购环节为研究对象，探究了引入回购契约之后的供应链整体利润，是否相较于传统的分散式采购模式得到了提升。本文分析了EPC模式中建筑供应链管理和供应链契约的研究现状，并确定了EPC模式下建筑供应链采购契约协调基本模型。在此基础上，比较了EPC模式下分散式和集中式决策建筑供应链采购模型。最后，引入基于回购契约的建筑供应链采购协调模型，并利用算例分析比较了三种采购模式。通过本文的研究，可以看出当前EPC项目中采用的分散式采购模式，相较于集中式采购模式，产生的建筑供应链整体期望利润更低。而引入回购契约之后，建筑供应链的整体利润能够达到集中式采购模式的利润水平，从而实现EPC模式下建筑供应链的协调。本文的研究能够推进EPC项目采购乃至整个项目建设工作的平稳运行，具有显著的现实意义。

Abstract: As a hot issue in the current construction industry, the EPC project has received extensive attention on how to ensure its performance and quality. This paper takes the procurement in the EPC construction supply chain as the research object. After the introduction of the repurchase contract, we explore whether the overall profit of the supply chain is improved compared with the traditional decentralized procurement model. This paper analyzes the current research status of construction supply chain management and supply chain contract in the EPC projects, and determines the basic model of procurement contract coordination in the construction supply chain under the EPC mode. On this basis, the procurement models of decentralized and centralized decision-making supply chain in EPC projects are compared. The construction supply chain procurement coordination model based on the repurchase contract is introduced. All the three procurement models are analyzed by using examples. Through the research in this paper, we can see that the decentralized procurement model adopted in the current EPC projects has lower overall expected profit than the centralized procurement model. After the introduction of the repurchase contract, the overall profit of the construction supply chain can reach the best profit level, thus achieving the coordination of the construction supply chain under the EPC mode. This paper can promote the smooth operation of procurement and even the whole project, which has significant practical significance.
