Interaticnal Joint Study 0n Digital Convergence of Telecommunicaticns and Broadcasting

由于数字创新，电信和广播正在融合，这使得市场边界变得模糊。融合在网络、平台和内容三个层面上进行。在以数字融合为基础的新市场迅速形成，企业采取纵横一体化、大联盟等战略行为的情况下，为了实现配置效率和生产效率，促进技术进步，提高公平性，需要采取什么样的政策？技术的最新发展和监管政策的最新演变使经济分析成为研究趋同政策问题的中心。为了加深对理论发展和政策走向的理解，1998年组织了国际研究小组。从那时起，我们一直在合作，将经济分析应用于趋同问题。我们的第一部分学术成果被出版为一本书，题为电信和广播的融合是日本，英国和德国，Curzon出版社，英国。在第二阶段的合作研究中，我们于2002年1月在早稻田大学和大坂大学举办了以有效频谱分配为重点的融合政策研讨会。我们还于2003年11月2日至4日在英国沃里克大学举行了一次国际研讨会，会上广泛讨论了三个主要议题：频谱分配和在几年内。

Due to digital innovation, telecommunications and broadcasting is converging, which makes the market boundaries blur. The convergence is progressing in the three layers : networks, platforms and content. When new markets based on digital convergence are rapidly creating and firms are taking such strategic behaviors as vertical and horizontal integration and grand alliances, what sorts of policies are needed to achieve allocative and productive efficiency, to promote technological progress, and to enhance equity? Recent developments in technology and recent evolvements in regulatory policy have made economic analysis central to the study of convergence policy issues. To deepen our understanding of theoretical developments and policy trend, the international study group vas organized in 1998. Since then we have been collaborate to apply economic analysis to convergence problems. The first part of our academic achievement was published as a book titled Convergence of Telecommunications and Broadcasting is Japan, UK and Germany, Curzon Press, UK. In the second period of our cooperative research works, we had a seminar on convergence policy, focusing the efficient spectrum allocation in January 2002 at Waseda University and Osaka University. We also had an international seminar at Warwick University, UK from November 2-4, 2003, in which three major topics were extensively discussed : spectrum allocation and within a few years.
