A Causal feedback relationship model for critical success factors of PPP projects based on system dynamics

The Study on causal feedback relationship between critical success factors of PPP projects is of great significance to the successful implementation and performance improvement of PPP projects. This paper aims to describe a set of critical success factors (CSFs) and establish a critical success factors causal feedback model to provide a tool to confirm the relationship between CSFs. Thirteen CSFs were derived from extend literatures, then were used to develop a causal feedback model based on the system dynamics method. PPP projects generally involve three different stakeholders, public sector, private sector, and public, this paper analyzed causal feedback between factors based on different stakeholders. This study suggests that, This study suggests that the direct factors influencing the stakeholders is different, at the same time, emphasize the public participation has important effects on PPP project success, causal feedback relations between CSFs will contribute to the PPP project sustainability and success.
