Abstract: The implementation of major infrastructure project (hereinafter referred to as megaproject) involves multiple organizations, which form complex stakeholder relationships. Safety management performance is greatly affected by the effectiveness of cooperation and organizational safety behaviors. In order to explore the effect of organizational safety behavior in megaproject(MOSB) in stakeholder network, stakeholder value network(SVN) analysis method is applied to initially build MOSB-SVN model to visually represent how safety value flow is delivered from one stakeholder to another, which contains 3 types Organizational Safety Behavior, 8 types of stakeholders and 61 value flows. The results indicate that the MOSB-SVN model could identify key stakeholders, key behaviors, and high-scoring value paths to obtain the value acquisition capabilities of all stakeholders and the execution effect of organizational safety behaviors. New ideas and suggestions for improving megaproject safety performance are provided at last.

Key words: megaproject; inter-organizational safety behavior; stakeholder value network; driver paths
