Resumen
Project sustainability has become a research hotspot in the construction industry and a crucial driving force for the successful delivery of projects. How enterprises can improve project sustainability performance and realize sustainable development by applying BIM has become an important research topic. In this study, based on the resource-based view and institutional theory, a relationship model of BIM application affecting project sustainability performance is constructed, and data from 449 questionnaires with electric power construction industry practitioners obtained by the two-stage data collection method are used to explore the relationship between BIM application and project sustainability performance, and to investigate the mediating role of green innovation and the moderating role of institutional pressures. The study found that: (1) BIM application has a significant positive impact on project sustainability performance; (2) BIM application has a significant positive predictive effect on green innovation, and green innovation plays a mediating role in the relationship between BIM application and project sustainability performance; and (3) under a high degree of institutional pressures, the positive relationship between BIM application and green innovation is strengthened, and, in this case, the mediating role of green innovation is enhanced. The study results help to expand the theoretical analysis of the relationship between BIM application and project sustainability performance and provide practical guidance for improving project sustainability. Finally, the data in this study only come from the power construction industry and do not differentiate between the types of green innovations, and further research could be conducted on these two aspects in the future.
