This study proposes a new industrial structure for the Japanese communications industry in the 21st century. The proposed industrial organization has a hierarchical structure with five layers, each of which corresponds to a functional description of BISDN technology. Each layer is then assigned a market structure (I.e., competition, regulated competition, or regulated monopoly). The proposed industrial organization can serve as not only a backbone of the BISDN-based communications infrastructure but also as a conceptual framework for guiding the NTT divestiture planned for 1995.
