PPP project life cycle renegotiation trigger event identification

Abstract

This paper analyzes the obstacles of PPP project contract implementation and PPP related contract content, finds out the uncertain events in the whole life cycle of PPP project, and further summarizes and filters it to get the renegotiation trigger event. Through literature review and case analysis, the causes of renegotiation trigger events were confirmed and their impacts were analyzed. Finally, based on the compensation of the contract status and the supplement of the contract status, the renegotiation control mechanism and the post-event problem supervision are proposed.
