Abstract: The relevant contents of the Outline of the 14th Five-Year Plan reflect the higher requirements for PPP projects, and the combination of the EOD model and PPP projects is strongly advocated to help PPP projects achieve high-quality development. In order to solve the risk-sharing problem of PPP+EOD projects, the article describes the project risk loss on the basis of risk association, and then constructs a risk-sharing evolutionary game model based on the perspective of evolutionary game and obtains the evolutionary stabilization strategies under different situations. The study shows that under the condition of risk association, different risk loss values are obtained from the risk intuition loss, which affects the strategy choice of government departments and social capital, thus leading to different evolutionary outcomes for the same risk.

Keywords: PPP project; EOD model; risk sharing; risk association; evolutionary game;
