The document discusses the emerging value network in the mobile phone industry in Japan and its implications for other countries. It describes how Japan moved beyond a traditional value chain model to a more complex value network with multiple sellers, buyers, and relevant industries like PC and internet. This network facilitated new mobile services around entertainment, general internet access, publishing, location-based services, retail/ticketing systems, and broadcasting. It concludes that the Japanese model demonstrates the complexity of relationships between firms, importance of strategic approaches, challenges of achieving critical mass, and role of new standards and policies in shaping an interdependent mobile ecosystem.
