Abstract
Deployment of broadband is now one of the major policy objectives in many countries, including Japan, Korea, the U.S., and across the EU, for example. The purpose of this paper is to conduct an empirical analysis to identify the factors affecting broadband service diffusion in OECD 30 member countries. There are no previous studies containing enhanced empirical analysis of the factors behind broadband services adoption including FTTx in multiple countries. This paper shows by panel data analysis that the number of CATV subscribers as broadcasting in the year of 2000 promoted CATV (BB) adoption, unbundling of copper local loops supported DSL adoption, and business strategies for making investment into FTTx and no unbundling regulation on optical local loops helped FTTx adoption. The paper also reveals that the three broadband technologies are substitute with each other. This analysis will provide an important basis for national broadband policy formulation in individual countries.
