The　incentive　problem　in　supply　chain　with　asymmetric　information　is　one　of　the　important　research　contents.　The　existing　supply　chain　research　results　are　obtained　under　the　condition　that　the　amount　of　the　principal＇s　information　is　given,　in　fact,　the　amount　of　the　principal＇s　information　is　optional.　Based　on　this　understanding　and　the　previous　research　results,　this　paper　constructs　a　new　monitoring　and　incentive　model　with　asymmetric　information　for　supply　chain　partnership.　The　paper　deepens,　extends　the　supply　chain　incentive　research　content　and　deepens　people＇s　understanding　of　supply　chain　management　.It　is　helpful　for　applying　the　theory　of　supply　chain　management.　©2010　IEEE.
