New regulatory institution for the convergence of broadcasting and telecommunications: A Korean case

This paper addresses a new case for the convergent regulatory institution for broadcasting and telecommunications in Korea. This paper emphasizes that, when considering a convergent regulatory body, Korea's main principle to establish is a reflection of the paradigm shift of convergence and IT industry. The proposal of the Korean Communications Commission addresses that as a prior factor. This paper deals with three characteristics in establishing the KCC: accommodating policy making and regulation together within a single institution; choosing a commission model as a new organizational type, which inherits a broadcasting legacy to ensure diversity and independence; combining content and network sector together. This paper attempts to show that the Korean model gives a power to the convergent regulatory institution to make the country remain one of the leading countries in information and communication sector as well as implement convergence of broadcasting and telecommunications successfully.     

Estimating network effects in China’s mobile telecommunications

1 Introduction 1 Both economic literature and legal literature have focused a great deal of attention on the phenomenon of network effects, or network externalities: “markets in which the value that consumers place on a good increases as others use the good.”[1] Network effects have important implications for structure and competitiveness of underlying market, as well as for regulation policy making. In China, theoretical developments of the concept have been introduced, but it still remains…

完善我国电信法律规制的思考

我国电信业发展总体不平衡,以长江三角洲区域为代表的经济发达区域对电信技术的发展有着强烈的渴求,对我国电信立法的内容和形式提出了新要求。应以全新的立法原则,努力构建新型电信监管体制;以融合竞争为背景,建立适应新科技革命要求的《电信法》;以立法为契机,形成合理有序的电信市场竞争环境;以信息、技术和法治的协调发展为目标,推动我国创新型国家建设向前发展。     

专利战略化情境下的产业核心专利态势分析

在现代专利环境中,专利申请动机越发趋于战略性,这为专利的价值评估及核心专利判定带来更多挑战。为了解决此类专利的价值评估难题,基于专利权人的战略意图构建专利战略指标体系。进而,以中国电信产业2001-2008年向美国专利局申请的历史专利数据为样本,利用线性回归分析实证验证了专利战略指标对专利价值的影响效应及解释能力,客观地赋予了每个指标权重。最后,通过该指标体系的加权求和,预测中国电信产业2009-2012年的美国专利价值并识别出各年的核心专利,继而探索产业关键技术布局。实证结果表明,中国电信产业的核心专利布局存在两大方面的隐患,即前沿技术领域涉入不深和本土申请人统治力不足。研究从专利申请战略动机的角度夯实了专利价值评估指标的理论基础,对于专利估值的管理实践具有重要的借鉴意义。     

新一代信息技术产业发展模式转变的演进机理——以中国蜂窝移动通信产业为例

基于行动者网络理论的通信标准化战略研究——以TD-SCDMA标准为实证

 借助科学的社会学研究理论——行动者网络理论分析中国在逐步从通信大国走向通信强国,从标准采用者走向标准制定者的进程中,如何战略性地推行本土标准。并重点从动机、行动和结果三个层面对每类行动者在标准化行动网络中的定位及行动策略加以分析。进而就标准化战略实施得到以下启示：标准的技术路线要在性能与兼容性、开放与封闭间找到平衡点;适度的政策资源供给;重视联盟的力量,努力打造一个囊括各主要利益相关者的支撑性联盟网络。     

Estimating network effects in China＇s mobile telecommunications

A model is proposed along with empirical investigation to prove the existence of network effects in China＇s mobile telecommunications market. Futhernore, network effects on China＇s mobile telecommunications are estimated with a dynamic model. The structural parameters are identified from regression coefficients and the results are analyzed and compared with another literature. Data and estimation issues are also discussed. Conclusions are drawn that network effects are significant in China＇s mobile telecommunications market, and that ignoring network effects leads to bad policy making.     

The concept of a university of the world

Abstract

Long‐distance education is now possible because of advancements and improvements in international telecommunications. This paper sets forth the concept of a “University of the World” in which students use computers, radio, and television to take courses in their chosen discipline and, in return, receive course credit and even academic degrees. The author describes the concept, its educational goals and objectives, the availability of courseware, the impact of global instructional technology, and questions of cost and technological capability. The organization, governance, funding, and operation of the University of the World are also described, including remarks on the benefits of membership and the functional value as seen from the student's perspective.
