Abstract
Moderne Kommunikationsnetze tragen zur Verbreitung von Wissen und Information bei und sind daher für die wirtschaftliche Entwicklung von Industrienationen wie Deutschland von zentraler Bedeutung. Insbesondere stellt der Umbau der Netzarchitektur vom traditionellen vermittelten Sprachtelefonnetz zum IP-basierten Datennetz zur Bewältigung aktueller und zukünftiger Datenaufkommen eine besondere Herausforderung, aber auch Chance für die beteiligten Akteure dar. Aus einer technologisch-ökonomischen Perspektive werden in diesem Beitrag die Wettbewerbspotentiale sowie die Rolle einer sektorspezifischen Regulierung in diesem Transformationsprozess analysiert. Dabei folgt die Argumentation der Einsicht, dass neue Wettbewerber nur in einen wachsenden Markt eintreten. Neue infrastrukturbasierte Wettbewerber müssen jedoch frühzeitig die Möglichkeit bekommen, sich Marktanteile im wachsenden Markt für Datentransport zu sichern. Aufgrund des sukzessiven Übergangs zum IP-basierten Datennetz hat Regulierung die Aufgabe, neuen Wettbewerbern den Zugang zu Elementen des traditionellen Netzes des etablierten Anbieters zu gewährleisten. Die Regulierung des Zugangs zu neuen Zugangsnetzen lässt sich dagegen nur in dünn besiedelten Regionen begründen, in denen aufgrund der hohen Aufbaukosten und der geringen Nachfrage kein infrastrukturbasierter Wettbewerb zu erwarten ist. In diesem Fall könnte sich die öffentliche Hand auch an der Finanzierung des Netzes beteiligen, um die Entstehung des Netzes selbst sicherzustellen. In Agglomerationsräumen schafft dagegen der Wettbewerb zwischen wenigen Kopf-an-Kopf-Wettbewerbern Anreize zur Investitionen in neue Zugangsnetze.
