In　the　dynamically　changing　external　environment,　it　is　the　core　issue　of　enterprise　innovation　strategy　that　how　enterprises　maintain　a　sustained　level　of　innovation　by　creating　their　own　capabilities.　In　addition,　the　open　innovation　proposed　by　Chesbrough　provides　a　new　way　of　thought　for　innovation　management.　This　essay　constructs　conceptual　models　of　several　sets　of　variables　relationships　between　environmental　protection　industry　innovation　performance　and　external　innovation　resources,　which　is　based　on　85　environmental　protection　enterprises　as　the　questionnaire　objects　and　a　path　analysis　of　the　model　is　conducted.　The　results　show　that　the　cooperation　with　horizontal　and　vertical　enterprises　can　significantly　affect　innovation　performance　only　by　virtue　of　the　intermediary　effect　of　the　enterprise　network　dynamic　capability,　and　government-industry-academy-research　cooperation　can　directly　improve　innovation　performance.　Mechanistic　study　not　only　reveals　that　the　joint　action　by　external　innovation　resources　and　network　dynamic　capabilities　can　influence　the　innovation　and　motivation　of　environmental　protection　enterprises,　but　also　reflects　that　a　major　source　of　environmental　protection　innovation　is　the　internal　resources.　This　provides　theoretical　guidance　for　enterprises　to　effectively　implement　the　open　innovation　strategy　in　the　innovation　practice.
