行政垄断影响下我国电信业发展影响因素分析

电信业已经成为我国社会和经济发展的基础性、先导性和战略性产业,电信业务量是反映电信行业发展的一个比较全面的指标。实证研究表明,国民经济总体发展状况、人口居住的密集程度,以及与电信行业有关的产业政策变化等是影响电信行业发展的主要因素。     

我国电信业竞争性失衡的成因及对策分析——基于竞争的自我颠覆性和网络外部性的视角

本文从竞争的自我颠覆性和网络外部性的双重视角分析了我国电信业的竞争性失衡问题。结果表明：竞争的自我颠覆性导致电信业由竞争格局走向垄断,网络外部性则加速了这一进程;在位运营商在网络外部性的作用下使得其均衡产量为跟随者均衡产量的2倍;我国进行的第三次重组能够在一定程度上逆转由于竞争的自我颠覆性导致的竞争性失衡,但是这种逆转只是暂时的,为了进一步促进有效竞争局面的形成,以及在长期内维持合理的竞争性局面,则需要均衡电信运营商的网络外部性。     

The competition among mobile network operators in the telecommunication supply chain

In the mobile telecommunication sector, the high competitiveness has increased the complexity of strategic interactions among operators. As the vertical integration has become anything but a choice and not a compelling technical solution, the contest takes place at different levels of the components of the operator value chain: the network infrastructure, the service development and supply, and the relationship with consumers.Mobile virtual network operators act as retailers and concentrate on the last segment of the value chain by establishing commercial agreements with hosting network operators, which act as manufacturers, to get access to radio communications infrastructure. Productive processes of mobile services offered by operators are different and this difference is imperceptible to customers. Processes difference mainly consists in the infrastructural diversity of the operators and implies different consequences on each network service element.A model has been defined to analyze the consequences of such diversity in the competition among HNOs, MNOs, and MVNOs by focusing the attention on the characteristics of the call path, in dependence of the types of operators. In fact, many variables interact to define the call path, such as marginal costs and revenues, infrastructural investments, and interconnection charges among operators. The analysis of the results, obtained by the model, gives information on variations of retail prices, market shares, and profit allotment, to adopt the proper strategies. In particular, the model results shed light on how certain MVNOs should enter the markets and adopt a collaborative strategy with HNOs. The model owns the capability of being applied to different contexts, thus representing for the regulator a potential instrument of relevant usefulness.     

Spectrum allocation and its relevance for competition

Spectrum is one of the most important production factors for mobile telecommunications operators. Spectrum policy is paramount as spectrum is a scarce resource allocated by regulatory authorities. Hence, when allocating spectrum and determining the potential use of spectrum, the regulatory authorities have a significant influence on the competitive situation in mobile markets.

基于价值链的电信企业竞争力指标体系的构建

迈克尔.波特提出的价值链理论界定了企业的各种价值活动,用于分析企业的竞争优势。电信企业应结合行业的经营特点和运营情况,对迈克尔.波特的价值链模型修正,识别出符合竞争力内涵的价值活动,构建电信企业的核心竞争力评价指标体系。     

市场需求、规模经济性与固定通信行业自然垄断性的清除

固定通信行业的规模经济性历来被认为是其自然垄断的条件,中国电信也因此长期处于垄断的地位。随着市场需求的扩大,固定通信行业的自然垄断性也随之消除。本文对中国固定通信市场的竞争状态进行了分析,通过计算市场容量和电信厂商的最优规模,测度出了市场所能容纳的最佳厂商数目。中国固定通信市场的发展已经具备了展开一定竞争的要素,新厂商的进入是必然的趋势。

Russian Telecommunication Company MTS Goes to the CIS

SUMMARY

The article deals with the outward internationalization of Russia's telecommunication company Mobile TeleSystems (MTS). This research investigates both target foreign markets and entry strategies of the company. In 2002, MTS started with entries to Belarus and Ukraine, followed by expanding to Uzbekistan and Turkmenistan in 2004. The choice of CIS countries was determined by knowledge of business environment and practices which are similar to Russia, and by economic and political ties inherited from the past. The basic strategy was acquisition of local mobile operators with the exception of Belarus where a joint venture was established. The article suggests that new market entries are expected.
