This　paper　analyzes　the　characteristics　of　emotion　state　and　group　behavior　in　the　evacuation　process.　During　the　emergency　evacuation,　emotion　state　and　group　behavior　are　interacting　with　each　other,　and　indivisible.　The　emotion　spread　model　with　the　effect　of　group　behavior,　and　the　leader-follower　model　with　the　effect　of　emotion　state　are　proposed.　On　this　basis,　exit　choice　strategies　with　the　effect　of　emotion　state　and　group　behavior　are　proposed.　Fusing　emotion　spread　model,　leader-follower　model,　and　exit　choice　strategies　into　a　cellular　automata　(CA)-based　pedestrian　simulation　model,　we　simulate　the　evacuation　process　in　a　multi-exit　case.　Simulation　results　indicate　that　panic　emotion　and　group　behavior　are　two　negative　influence　factors　for　pedestrian　evacuation.　Compared　with　panic　emotion　or　group　behavior　only,　pedestrian　evacuation　efficiency　with　the　effects　of　both　is　lower.
