“电子业务”与“业务电子”

"电子业务"与"业务电子"源自"电子商务"与"商务电子".电子商务(业务)与商务(业务)电子应从两个群体解释起. 从最朴素的意义上来理解,电子商务(业务),就是利用电子手段来从事商务(业务)活动.很明显,电子手段,也就是我们说的IT和网络技术,是为商务(业务)活动服务的,它是决定电子商务(业务)能否成功的重要手段.     

IP RAN技术发展前景浅析

随着3G和LTE牌照的相继发放,无线接入网业务流量迅速增长,现有使用基于SDH技术的MSTP承载网已面临相当大的压力.为配合LTE网络建设,采用了IP RAN/PTN等新型的分组传送技术建设无线接入承载网络.本文从IPRAN的技术特征的角度出发,以IP RAN技术在承载网发展中所处优势,分析了IP RAN技术作为未来宽带业务承载网络技术建设的必要性和重要性,总结出IPRAN技术是无线及数据宽带业务需求发展的必然趋势.     

光传送网演进过程中的OTN技术应用分析

随着数据流量在网络中激增,IP业务逐渐成为电信网络的主导业务,由于IP业务本身的不确定性和不可预见性,特别是IP业务的多样性、精细颗粒和大颗粒等特性对作为电信业务基础承载网络的光传送网提出了新的挑战.本文总结出在新业务驱动下光网络的近期演进方向为向统一传送网演进,对于光网络向统一传送网演进过程中重要的OTN(Optic...     

基于LECOM模型的农村电信成本研究

目前政府高度关注农村问题,但农村通信发展滞后现象还没有引起足够的重视,因为农村通信建设是农村经济发展,走向小康社会的重要前提。随着我国电信业竞争格局的逐步形成,建立普遍服务基金势在必行,以保障对广大农村地区的投入,促进农村电信通信的发展。如何测算农村电信话成本,进而确定普遍服务基金的资金缺口,是能否保证普遍服务实施的关键。     

A note on tariffication strategy cases in telecommunications

The tariff policy of a telecommunication operator has a strategic importance on achieving optimal revenues and a fundamental impact on its position in the competition with other operators on the liberalised telecommunication market. The payment for a connection through a telecommunication network may be determined by a rate for one call unit, by the duration of the call unit and their count during a call. An operator derives the rate and the duration of the call unit from a detailed analysis of large databases that contain statistical data on counts and duration of particular calls depending on the type of call. Usually only the operator knows these data files and keeps them confidential. In this note we show how it is possible to estimate revenues from telecommunication traffic only knowing a set of basic parameters.     

Estimating Direct Gains in Consumer Welfare in Telecommunications Sector

This paper discusses the benefits of product and process innovation as well as deregulation in consumer telecommunication products markets. The twin trends of price reduction and new features have benefited consumers. These major changes have taken place alongside deregulation. Using the data from Organisation for Economic Co-operation and Development telecommunication reports, the paper provides estimates of gains in consumer welfare over the years. These direct gains are significant (hundreds of billions of dollars) and thus justify the public investment that goes into the telecommunication infrastructure improvement.     

我国通信业客户忠诚驱动因素研究

客户忠诚指客户行为的持续性,它对确立企业的核心竞争力具有重要影响。文章认为,客户忠诚是内外部环境因素共同作用的结果。而通讯服务质量、信任、转网成本、员工忠诚是影响通讯业客户忠诚的重要因素。其中,良好的通讯服务质量是维系客户忠诚的保障;信任是客户再购买行为产生的前提;转网成本对通讯业客户忠诚有着不可忽视的影响;员工忠诚有助于客户忠诚的建立。我国通讯运营商要建立客户忠诚,必须以客户导向的营销理念作为企业经营管理的主导思想;加强技术创新,为客户提供全方位的优质服务;与客户之间建立相互信任的合作关系,为长远合作奠定基础;提高转网成本和员工忠诚度,为建立客户忠诚打下坚实的内部基础。     

The relationship between organizational culture and market orientation in the Greek telecommunication companies

The modern business environment is characterized by intense competition, which has led telecommunication companies to a continuous race towards gaining and maintaining a competitive advantage. In order to succeed, telecommunication companies “cultivate” market orientation and market oriented cultures as non-imitable characteristics, capable to ensure long–term corporate viability and growth. This paper provides an insight into the Greek telecommunication industry by: a) revealing the coordination between market orientation strategies with corresponding culture, b) the relationship between extrovert-type cultures with performance and c) how special traits of telecommunication providers (size and age) influence the degree of market orientation and the dominant culture type (introvert or extrovert). The paper contributes: a) to the creation of national cultural profile in the telecommunication industry, which can become a starting point in a wider trial to create a European industry profile, b) to the empirical testing of the correlation between culture and market orientation and c) to the examination of the extent to which background factors (such as firms’ age and size) should be taken into account during the implementation of a business strategy.     

行政垄断影响下我国电信业发展影响因素分析

An empirical study about the impacts of China's accession to the WTO on the telecommunications industry in China

Post‐China's accession to the World Trade Organization (WTO), China's telecommunication industry now needs to face a much stronger competition in a relatively open market that has a number of diverse rivalries. There are specific benefits and risks associated with both domestic telecommunication (telecom) companies and foreign investors in the telecommunication or information technology area. To meet with these new challenges and take advantage of the competitive, strategic advantages to penetrate the market, both China's telecom industry and foreign investors must understand the impacts of China's accession to the WTO on its telecommunication industry and hence make the necessary adjustments and/or implementation improvements. In specific, we carefully examine the impacts such as prices, quality, and local protectionism in this article. We draw the findings based on the data collected from a survey and the resulting statistic analysis.
