Prefabricated construction (PC) activities are geographically fragmented, temporally disrupted, resulting in numerous and complex interfaces. It is stakeholder collaboration by integrating diverse resources within the PC industry to potentially address the factors that impact interface management performance. Previous studies have explored the impact factors of interface management performance without deeply considering the stakeholder and their linkages with the impact factors of interface management. Therefore, this study used a two-mode social network to investigate the impact of the interface management performance of sustainable PC from a stakeholder perspective. Firstly, 24 factors impact interface management of sustainable PC, as well as 12 stakeholders with power to address the factors, were identified based on a literature review and interviews with experts. Subsequently, Stakeholder-factors relationships were judged by a designed questionnaire. Then, the centrality and core-periphery structure analysis methods were adopted to study the network. The findings revealed that developers, general contractors, subcontractors, designers, and suppliers are the core stakeholders, with improved collaboration between these five stakeholders (42%) able to address 18 core factors (75%). The factors that have the most significant impact on the interface management performance of prefabricated construction include understanding and trust, communication and learning, and cooperative attitudes among participants, the effectiveness and timeliness of information communication, formal interface management processes, technical innovation, and the perfection of standards and specifications. By prioritizing these factors, the complexity of the network can be successfully decreased and interface management performance can be improved. This study not only contributes to identifying the impact mechanism of stakeholders on the factors of interface management performance, but also contributes to promoting stakeholder cooperation to improve the sustainability of prefabricated construction.
