Based　on　Organization　Evolution　Theory　knowledge　diffusion　performance　of　innovation　network　is　studied　from　the　perspective　of　environmental　choice　and　organization　adaptation　in　our　work.　A　new　knowledge　diffusion　model　based　on　multi-agent　simulation　is　put　forward　to　solve　the　defects　of　the　existing　ones　without　regard　to　how　competition-cooperation　degree　between　agents　and　different　organization　learning　patterns　jointly　impact　on　knowledge　diffusion　of　innovation　network.　A　series　of　conclusions　are　obtained　through　simulation　experiments.　These　conclusions　are　verified　by　the　longitudinal　development　of　Liushi　innovation　network　for　low-voltage　apparatus.　©　2017　Taru　Publications.
