国际工程EPC项目采购集成管理

Integrated procurement in international EPC projects

设备和物资采购在国际工程设计、采购和施工一体化(EPC)项目中具有重要地位。已有对供应链一体化与采购管理的关系的研究多侧重理论分析,对EPC项目关注较少,对二者的作用机理还缺少系统实证分析。该文提出国际工程EPC项目采购集成管理概念模型,并通过问卷数据,使用偏最小二乘法结构方程模型分析验证模型路径。分析结果揭示了采购集成管理中的3条路径:关系集成直接影响采购绩效;关系集成促进采购过程管理,进而影响采购绩效;关系集成通过信息集成促进采购过程管理,进而影响采购绩效。其中,关系集成通过信息集成对采购过程管理的间接作用大于其对采购过程管理的直接作用,关系集成对采购绩效的直接作用大于其通过信息集成和采购过程管理对采购绩效的间接作用。该研究结果有助于指导EPC承包商有针对性地进行采购集成管理,提升采购绩效。

The procurement of equipment and materials plays a critical role in international engineering, procurement, and construction （EPC） project delivery. However, there is a lack of empirical research to clarify the causal mechanism between supply chain integration and procurement. A conceptual model of integrated procurement is developed based on supply chain integration.Questionnaire data is used to explore the effect of supply chain integration on procurement using a partial least squares structural equation model （PLS SEM）. The results show that relational integration directly affects procurement performance, relational integration affects the procurement processes which helps improve the procurement performance, and relational integration facilitates information integration which further improves the prgcurcment processes and procurement performance. The relational integration indirect effect on the procurement processes via information integration is larger than its direct effect on prucuremcnt processes and the relational integration direct effect on procurement performance is larger than its indirect effect on the procurement performance via information integration and procurement processes. These results provide guidance for EPC contractors choosing procurement strategies.
