| Abstract |
This study investigates the impact of Global Project Management (GPM) capabilities on project performance in Public?Private Partnership (PPP) projects, focusing on the construction phase. GPM is conceptualized in this study through three core dimensions: organizational capability, human resource capability, and process capability. In addition, the study examines the moderating roles of construction firms’ willingness to adopt GPM and financial institutions’ demand for GPM practices. Based on a survey of 296 practitioners with experience in PPP construction projects in South Korea, multi-stage regression analyses were employed to verify the relationships between GPM capabilities and project performance outcomes, including schedule, cost, and client satisfaction. The findings demonstrate that PMO maturity, the professional competence of both direct participants and support personnel, and the level of application of GPM methodologies have statistically significant positive effects on project outcomes. However, the application of PMIS showed a limited effect, indicating the need for greater digital adaptability in the field. Furthermore, the moderating effects of construction firms’ internal support and financial institutions’ external expectations were partially supported. This study provides empirical evidence of the importance of GPM in the success of complex PPP construction projects. It offers practical insights for construction firms on establishing GPM systems and strategies and highlights the role of external stakeholders in enhancing project performance. Future research is encouraged to incorporate objective project data and explore cross-national comparisons of GPM practices. |
