Based　on　the　analysis　of　the　dissipative　structure　about　the　innovation　network　with　openness,　nonlinear,　non-equilibrium　and　self-organizing　characteristics,　this　paper　builds　a　self-organizing　model　of　the　innovation　network,　and　then　makes　a　thorough　study　in　the　evolution　law　of　the　innovation　network.　The　research　finds　that　the　self-organizing　characteristics　of　the　innovation　network　mainly　show　in　two　aspects,　that　is,　the　mutual　action　among　innovation　agents　and　the　mutual　action　between　the　network　and　the　environment.　Furthermore,　it　is　found　that　the　evolution　process　of　the　innovation　network　can　be　divided　into　three　stages:　incubation　period,　growth　period　and　mature　period.　©　2010　IEEE.
