Its implementation scheme is discussed and its Session Initiation Protocol (SIP) signaling exchange flow is described. Target user groups are predicted based on the analysis of the strengths and weaknesses of the PoC service. The article purports that the PoC system could undoubtedly be used as a platform for new services such as multimedia messaging, instant messaging, presence, and picture receiving and sending. Just like the short message service, the PoC service will help the terminal vendors, equipment vendors, content providers and operators setup a win-for-all industrial value chain.展开更多

Result indicates that during the sample period, China＇s service exports measured by forward-linkage decomposition method accounted for around 35% in its total export. While the value of services exported directly through the service sector accounted for a falling share, the value of services exported through other sectors represented an increasing share. China ranks second in the world in terms of market share of service exports. However, the revealed comparative advantage （RCA） of China＇s service exports and export sophistication remains limited.展开更多

The typical cases were provided;the optimization of utilization method of network resources was put forward;the subject theme navigation was developed;and the information sharing space of specific discipline and other working strategies were carried out. The experience and enlightenment of active service for subject construction, priority service for key subjects, subject service by lay and step and seizing of the opportunity of subject service were summarized, which developed ideas and provided reference to the establishment of deep subject services of general libraries of colleges and universities.展开更多

The VAT is a highly harmonized consumption tax within the European Union （EU）. VAT operational rules have been set down by the relevant directive of the Council of the EU. Under the directive, it is possible to select either exemption or taxation of financial transactions. Only the first option is permitted in the Czech Republic. Pros and cons of both models are described, in particular, the problems with determining the difference between financial transactions and other similar performance that must always be subject to tax. Potential lower VAT revenue or tax base assessment, as appropriate, seems to be crucial in the case of the taxation of financial transactions.展开更多

However, the investing resource is usually limited in practice. This paper investigates VAS investing and pricing strategies for a two-sided platform under investing resource constraint. We reveal that with VAS investment, Subsidizing can still be done to enlarge users＇ demand, even when the investing cost becomes higher. For optimal pricing strategies, the network effect will be the dominating determinant if the gap between two marginal cross-side benefits （i.e. the benefit that users obtain when each new user join the other side of the platform） is large. Interestingly, we show that with the increase of the marginal investing cost, users might either be priced higher or lower. If the marginal investing cost increases to a high level, and the gap between the two marginal cross-side benefits is large, lowering the access fee for users possessing the higher eross-side network effect does not necessarily compensate more profit loss caused by higher cost. Moreover, after VAS is developed, raising the access fee for those whose marginal investing benefit is large does not necessarily generate more profit as well. The opposite strategy further enlarges users＇ utility, and promotes the investment to benefit more users.展开更多

This article analyzes the relation between telecom service revenue and traffic volumes of telecom service and deduces the method of measuring the total change in tendency of telecom price, which is based on the consumer＇s actual payment for telecom services. After describing the changing trend of TSP with the time series data from 1949 to 2000, the TSP showed a continuous declining tendency during 1949～1975. In contrast, the TSP showed a rising tendency from 1976 to 1991 and a sharp declining trend after 1992. Empirical tests and actual background of telecom reform support the results.展开更多
