The Role of Knowledge Sharing in Linking Leadership, Team Collaboration, and Environmental Sustainability Practices to Project Success in the Construction Industry

Abstract

This study examines how leadership effectiveness, team collaboration, and environmental sustainability practices influence project success, emphasizing the mediating role of knowledge sharing in the construction industry. While prior research has investigated these factors separately, few studies have explored their combined effects through a mediated framework. A quantitative research design was employed, and data were collected from project managers and team leaders using structured questionnaires. Structural equation modeling (SEM) was applied to test the hypothesized relationships and the mediation effect. Results reveal that leadership effectiveness, team collaboration, and environmental sustainability practices positively impact project success, with knowledge sharing significantly mediating these relationships, thereby enhancing their overall influence. The study contributes original insights by integrating leadership, collaboration, and sustainability with knowledge sharing as a mechanism for achieving successful project outcomes. These findings provide actionable guidance for managers and policymakers to improve project performance in the construction industry by fostering effective leadership, collaborative teams, sustainable practices, and active knowledge sharing.
