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，揭示数字社会中市场体制转型的本质和问题。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传播政策的平台。来自经济、法律、政策、商业和产业组织研究的专家们在这个平台上交换了意见。此外，我们还与加州大学伯克利分校的一组研究人员保持联系，以增进两国之间的相互了解。我们邀请了John Zysman教授到东京，并为那些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形成了Toshihiko Hayashi主编的《下一代网络的竞争政策》一书，在这本书中，我们主张在电信行业采取必要的竞争政策，这将受到下一代网络的出现的深刻影响。Toshihiko Hayashi写了一篇更技术性的论文，“NO和VNO：干扰，竞争和增长。”本文将一个捕食者-猎物模型引入到网络运营者与借用NO网络设备的虚拟网络运营者之间的关系中。主要结论是，通过放宽NO设施的准入条件，鼓励NO和VNO的增长战略，引导NO多样化其服务，我们可以在扩大的市场中实现NO和VNO共存的长期平衡。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Toshihiko Hayashi之间继续进行，Toshihiko Hayashi计划于10月前往伯克利，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.
