Inquiries into the Transformation of Market in the Digital Society

本研究旨在通过理论研究、制度研究和实证研究，揭示数字社会市场体系转型的本质和问题。在研究的第二年，我们继续组织研究研讨会，作为讨论政府信息和通信政策的平台。来自经济、法律、政策、商业和产业组织研究的专家在这个平台上进行了交流。此外，我们还与加州大学伯克利分校的一批研究人员保持联系，以增进两国的相互了解。我们邀请了John Zysman教授来东京，并为对学术界和研究机构感兴趣的人举办了研讨会。我们的部分研究成果是《下一代网络的竞争政策》一书，在书中，我们倡导电信行业必要的竞争政策，该行业将受到下一代网络的到来的深刻影响。林俊彦(Toshihiko Hayashi)撰写了一篇更具技术性的论文，题为《NO和VNO：干扰、竞争和增长》。本文将捕食者-食饵模型引入到网络运营商和虚拟网络运营商之间的关系中，虚拟网络运营商从网络运营商那里借用网络设施。主要结论是，通过放宽NO设施的使用期限，鼓励NO和VNO的增长战略，并引导NO使其服务多样化，我们可以达到NO和VNO在扩大的市场中共存的长期均衡。这项研究产生的联合研究安排将在加州大学伯克利分校和林俊彦之间继续进行，林俊彦计划于10月份访问伯克利，讨论进一步研究的可能议程。

It was the purpose of this study to lay bare the nature and problems in the transformation of market system in the digital society by theoretical, institutional and empirical studies.In the second year of the study, we continued to organize the research seminar as a platform for discussions focusing on the information and communication policy of the government. Specialists from economic, legal, policy, business and industrial organization studies exchanged their views on this platform. Furthermore, we kept contact with a group of researchers in University of California at Berkeley to enhance mutual understanding in the two countries. We invited Professor John Zysman to Tokyo and gave seminars to those who are interested in the academia and research institutions.Part of our research resulted in the book, Toshihiko Hayashi ed., Competition Policy for the Next Generation Network, in which we advocated the necessary competition policy in the telecommunications industry which will deeply be affected by the advent of the next generation network. A more technical paper has been written by Toshihiko Hayashi, "NO and VNO : Interference, Competition and Growth. " The paper introduces a predator-prey model into the relationship between a network operator and a virtual network operator who borrows the network facilities from NO. The main conclusion is that by easing the term of access to NO facilities, encouraging the growth strategy of NO and VNO and leading NO to diversify its services, we can attain a long run equilibrium in which NO and VNO coexist in an expanded market.The joint study arrangement that resulted from this study will be continued between UC Berkeley and Toshihiko Hayashi, who is planning a trip to Berkeley in October to discuss the possible agenda of further research.
