Abstract:
Mobile operators in saturated markets increasingly favor mobile network sharing (MNS) over facility-based competition. Previous research examining MNS primarily focused on its positive effects while the negative effects were largely overlooked. This study proposes a decisionmaking model using an analytic hierarchy process (AHP) technique to evaluate decision-making criteria among various types of MNS policies. The decision-making model was applied to wireless broadband (WiBro) services in Korea to determine the relative importance of both positive and negative evaluation criteria and preference among multiple types of MNS policies. Positive evaluation criteria (i.e., efficiency) were far greater in importance than negative evaluation criteria (i.e., competition harm).
The preference for adopting MN among five alternative approaches was also revealed. The study findings offer immedite policy insights in Korea and provide a decisionmaking framework for policy makers in other countries to utilize.
