Presently,　a　conventional　coalition　structure　can　no　more　cover　all　the　types　of　cooperative　structures　in　practice,　external　cooperation　between　the　coalitions　also　affects　the　payoff　allocation　between　the　participants.　We　propose　a　solution　to　solve　the　bargaining　problem　with　level　structure　by　defining　for　each　coalition　and　each　level.　The　solution　concentrates　on　the　bargaining　of　the　coalitions　with　each　other　at　each　level.　Furthermore,　we　discuss　the　applications　of　this　solution　to　bankruptcy　games　with　level　structure.　The　proposed　solution　generalizes　the　bargaining　solution　with　conventional　coalition　structure,　which　can　be　utilized　in　more　cooperative　types　with　level　structures.　(C)　2019　The　Authors.　Published　by　Atlantis　Press　SARL.
