It　is　studied　that　the　competition　and　vertical　cooperation　between　one　ocean　carrier　and　two　freight　forwarders.　In　addition,　two　freight　forwarders　have　different　market　positions.　We　observe　that　the　ocean　carrier　or　freight　forwarders　canvass　for　cargos,　which　influences　the　equilibrium　profits　and　channel　structures　in　Stackelberg　game.　We　show　the　integration　and　sharing　between　the　ocean　carrier　and　freight　forwarders.　Comparing　parties＇　profits　with　profit　sharing　or　integration　depended　on　network　externality　and　product　differentiation,　we　find　that　the　Nash　equilibrium　is　the　ocean　carrier　canvasses　for　cargos　and　the　integration　or　sharing.　Copyright　©　2019　by　Science　Press.
