【正文】 work that represents and integrates four perspectives from four major stakeholders: the technology perspective from the technology developers, the market demand perspective from the customers, the business model perspective from industry and the government policy perspectives. . TechnologyTechnology is viewed as humanoriginated advances that increase the effectiveness and efficiency of specific tasks (Good amp。 Schultz, 2000). The development of new information technologies is expected to result in improvements in firm performance, such as reducing transaction costs and closer coordination of economic activity among business partners (Malone, Yates, Benjamin, 1987。 Mukhopadhyay, Kekre, amp。 Kalathur,1995). Likewise, the development of telemunication technologies is expected to result in performance improvements such as cost saving, better or higher quality of service, new functions or improved capability and environmental protection. Considering the nature of mobile munication technology, the paper analyzes technology issues in terms of four performance dimensions: cost savings, environmental protection, roaming capability and quality of service.. Market demandSatisfying customers’ needs is at the core of success in any business endeavor (Porter, 1985). Technology developments are primarily driven by the market forces of demand. Inventors develop products to meet demands in the marketplace. If profits are possible through the mercial application of these products, entrepreneurs will see these benefits and drive the product to mercial realization. Thus, the underlying development and mercialization of technology is governed by economic forces within a marketplace (Basalla, 1989). Some studies of mobile merce also indicate that longterm mobile merce business success is likely to emanate from consumeroriented, rather than technologybased strategies (Clarke, 2000). This paper will analyze market demand along three dimensions: target market, size of market and potential growth.. Business modelA business model constitutes an architecture for the product, service and information flows, including a description of the various business actors and their roles, a description of the potential benefits for the various actors and a description of the sources of revenues (Timmers, 1999). A business model consists of the following ponents: customer value, scope, pricing, revenue source, connected activities, implementation, capabilities and sustainability (Afuah amp。 Tucci, 2001). Business models should work as a mediating construct between technology and economic value. The business model maps from the technical domain of inputs to the economic domain of outputs and the essence of a business model is ‘‘how you get paid’’ or ‘‘how you make money’’ (Chessborough amp。 Rosenbloom, 2002). The paper will address the business model from the following three aspects: value proposition, value chain, and petitive strategies.. Government policyRegulation is a form of control of an industrial activity by government (Waterson, 1988). Traditionally, telemunications has been a highly regulated industry. The nature of increasing returns to scale associated with telemunications has granted legitimate excuses for governments to acmodate the monopolistic status of the industry through various regulations (Xing, 2001). Despite some trends towards deregulation the regulatory process remains one of the most powerful ways in which government can influence activities in the telemunication industry (Weidenbaum, 1977) and government interference in the telemunication industry has spanned virtually all dimensions of business activity: ownership, entry, pricing and output choices. (Boylaud amp。 Nicoletti, 2001). The Chinese government has played a significant role in the development of telemunications in China. Under the umbrella of policy, this paper will discuss aspects of government objectives, government licensing, government support and government price regulation. As the above discussion shows, all four stakeholders play significant roles and their viewpoints cannot be ignored or considered separately. The following sections will analyze and pare XLT and 3G following these theoretical assessment frameworks.4. Market demand perspectiveThis section will review the mobile munication market in China and identify the target markets for XLT and 3G. It will then analyze the market size and the growth potential of these markets. . Overview of Chinese mobile telemunication marketsThe mobile munication market in China can be divided into three segments: highend, middlelevel, and lowend (Li, 2003). The highend market includes businessmen, high ranking managers, field service engineers, and journalists who have the ability to pay and are frequently on the move and in great need of highquality munication. It also includes early adopters of new mobile services such as young IT professionals and university students. All of the highend users already have mobile phones and use them heavily. The middle level market includes salaried or retired people and other students. These are people in moderate need of munications with local mobility. This group of people does not have high purchasing power. Their spending on munication is less than RMB 100 yuan (US $16) per month. Although most middle level users have mobile phones, they use them only when it is necessary. The lowend market includes farmers, low ine workers and those who usually stay locally. Their spending on munications is less than RMB 30 yuan (US $8) per month. The vast majority of them do not even have regular fixedline phones.. Target market for XLT and 3GBased on the market segmentation above, the target market for XLT is the lowend market and middlelevel market while the target market of 3G is the highend an alternative to the current, rather expensive cellular munication services, XLT’s lowcost ‘‘wireless local call’’ makes mobile munic
