In　this　Paper,　I　attempted　to　promote　the　two-party　game　to　tripartite　game　in　studying　emergency　crisis　management　during　large-scale　activities,　which　focused　on　behavioral　characteristics　of　venue　management　departments,　fire　departments　and　involved　people.　Then,　moral　hazard　issues　got　in-depth　analysis　in　the　model,　thus　I　proposed　several　proposals　how　to　reduce　negative　impact　of　moral　hazard　and　improve　the　efficiency　of　crisis　management　feasibility.　Finally,　I　introduced　punishment　variable　to　reflect　what　would　happened　to　the　efficiency　of　crisis　management　in　order　to　provide　theoretical　basis　for　designing　reward　and　punishment　mechanism.
