The　essence　of　the　object　of　intellectual　property　right　is　information.　The　intellectual　property　is　the　source　of　competitive　advantage　for　enterprises.　Based　on　the　information　night,　the　competitive　advantage　of　intellectual　property　has　five　information　-　related　characteristics.　The　characteristics　of　intellectual　property　come　from　the　sharing　quality　of　intellectual　products.　The　sharing　quality　determines　the　great　diversity　between　intellectual　property　and　tangible　property.　Constructing　the　competitive　advantage　of　intellectual　property　means　developing　information　-　based　industrialization.　Facing　the　complicated　development　trend　of　international　intellectual　property　protection,　enterprises　should　construct　the　competitive　advantage　of　intellectual　property,　with　regard　to　first　-　mover　advantage,　scale　advantage,　differential　advantage,　low　-　cost　advantage　and　sustained　advantage.
