Research In 3G And Communications Industry Economies Of Scale Validity

In the 21st century, the world entered the era of science and technology to tell the development of the same time, technology has become a major production in the major competitive forces and businesses. As the world's progress, technology, people can no longer meet in the only cell phone calls and send text messages, but also the need to move gradually and efficient network of life. Increasingly in demand in this market environment,3G came into being. In the 21st century, some European and American countries is more widespread 3G applications, the technology is relatively mature, relatively speaking, sub-put from the 3G market, the effectiveness of the communications industry in these countries also gradually increase, to reflect in some foreign countries the communications industry,3G economies of scale for the communications industry is valid.Since 2003, China will develop 3G networks and put it on the agenda, the domestic big three mobile operators have begun to delegate some communications development company for their needs operators 3G network technology research and development, In 2008, China Mobile, China's self-developed standards based on TD-SCDMA network, China Unicom In addition to maturity based on the configuration of the international WCDMA network, China Telecom has developed a CDMA2000 network. Beginning in 2009,3G officially into the market, and the timely adjustment of 3G services according to market demand, while the effectiveness of the communications industry economies of scale are also starting to show.DEA is just the rise of operations research in recent years, the statistical algorithm to analyze the data is mainly used to calculate the conclusion that the data and the research units and the effectiveness of the field strength of the economy. Now the world's various industries and fields of application are very extensive, but because of 3G in China is an emerging technology, we do not post or experts to DEA method is used in 3G and the effectiveness of the communications industry studies of economies of scale in. This paper uses China Mobile, China Unicom, China Telecom three mobile operator from 2007 to 2009, part of the financial report, based on these data, statistical analysis using DEA methods, the last of the 3G and the communications industry, economies of scale and effective sex.I read a lot of references by journals and news reports, this paper describes the development of 3G in the country at this stage in the development of the current situation and the problems encountered, and further elaborated on the future development trend of 3G. The article also raised the significance of this study is the 3G and the communications industry through economies of scale related to the effectiveness of research to identify the communications industry's future development path, to find a way to maximize economic benefits.Subsequently, the article related to economies of scale made a presentation and a detailed description of the concept of economies of scale and characteristics. The article also describes the characteristics of the communications industry sectors, the development of economies of scale of the communications industry will be benefited, and that the 3G to the communications industry, the opportunities and the current 3G in the operations of the communications industry.Next, the article also 3G and 2G mobile communication before were compared, indicating the existence of the advantages of 3G and 3G industry development status and development trend of 3G technology and explains the reference to the economic impact of the communications industry. Finally, the paper of DEA methods in detail, and explains the application of DEA methods and application areas of effect, describes the indicators of economies of scale assessed the effectiveness of the selection, calculation and analysis out of the data were analyzed and summarized.This innovation is the first time that DEA method is used in communications industries, although the 3G is an emerging technology, just put on the market, but 3G mobile communications in the future development of a very important position occupied, the researchers in 3G effectiveness of the communications industry economies of scale in the occupied position is very necessary.Calculation, only China Mobile, China Unicom, China Telecom Corporation from 2007 to 2009, three years of financial reports in 2009 to enter the 3G market, so in order to analyze the accuracy of the 3G and the communications industry economy effectiveness of the relationship requires more data to be calculated and analyzed, but only has 3 years of data that is not very accurate, in the next few years, as the maturity of 3G technology in the market share position gradually stability, should be able to get more accurate results by analyzing.
