This　research　of　college　teachers＇　knowledge　collaboration　is　from　the　human　perspective　by　the　system　dynamics　methods.　First,　the　human　factors,　which　affecting　the　knowledge　collaboration　efficiency,　include　three　dimensions　of　the　individual　ability,　psychological　utility　and　social　relations.　Second,　the　casual　loop　diagram　is　depicted　between　the　human　factors＇　three　dimensional　and　knowledge　collaboration　efficiency,　and　the　differential　equation　is　been　build　to　express　the　relationship　between　the　variables.　Third,　according　to　the　trends　change　of　the　related　variables,　we　put　forward　the　three　effective　measures　from　the　human　perspective,　that　is　improving　individual　capacity　through　the　training　system,　improving　psychological　utility　by　incentive　and　constraints　mechanism,　and　building　a　good　relationship　from　the　trust　culture.　Finally,　we　point　out　the　limitations　and　prospects　of　this　research.
