Nach den Ergebnissen einer neuen Studie des ifo Instituts hat der Ausbau von Breitbandnetzen positive Effekte auf das Wirtschaftswachstum. Die Analyse der jährlichen Daten von 25 OECD-Ländern über den Zeitraum 1996 bis 2007 zeigte, dass nach der Einführung von Breitbandinfrastruktur in einem Land das Pro-Kopf-Einkommen durchschnittlich um 2,7 bis 3,9% höher liegt als vor der Einführung. D.h. durch eine Erhöhung der Breitbandnutzerrate in der Bevölkerung um 10 Prozentpunkte steigt das jährliche Pro-Kopf-Wirtschaftswachstum um 0,9 bis 1,5 Prozentpunkte. Diese 10 Prozentpunkte entsprechen ungefähr dem Abstand, um den die Breitbandnutzerrate in Deutschland im Jahr 2003 geringer war als in den führenden OECD-Ländern. Hätte Deutschland im Jahr 2003 seine Breitbandnutzerrate um 10 Prozentpunkte gesteigert, wäre das BIP pro Kopf im Jahr 2007 um 3,7 bis 5,9% höher gewesen.
