Knowledge　sharing　was　the　most　important　way　to　obtain　resources　for　the　nodes　in　the　network　organization.　The　synergy　effect　generated　from　knowledge　sharing　could　rich　the　network　organization　resources,　and　it　helped　maintain　competitive　in　the　network　organization　developing　process.　This　paper　analyzed　the　impact　of　the　knowledge　sharing　on　the　nodes,　and　the　factors　that　affected　the　knowledge　sharing　synergy　effect.　Finally,　a　synergy　effect　function　was　proposed.　Through　analysis,　we　got　that　the　nodes　in　the　network　organization　should　actively　take　participate　in　knowledge　sharing　and　improve　their　own　synergy　learning　ability.　It　could　help　enhance　the　communication　and　reduce　the　difficulty　of　knowledge　sharing,　then　improve　the　overall　performance　of　the　network　organization.　©　(2012)　Trans　Tech　Publications,　Switzerland.
