摘　　要：研究背景 2009年1月7日，我国工业和信息化部发放了三张3G牌照，批准中国移动增加基于TD—SCDMA技术制式的3G牌照，中国电信增加基于CDMA2000技术制式的3G牌照，中国联通增加基于WCDMA技术制式的3G牌照，其中TD—SCDMA为我国拥有自主产权的3G技术标准。此举标志着我国正式进入3G时代。In 2009, China's 3G market grew rapidly with a smooth start. The operators' 3G network construction progressed with a high speed, 3G networks covered most cities at the end of year, and 3G users also increased fast. As of December 2009, China's 3G users overtook 15 million. The three operators have been competing across-the-board in technology, business and marketing. At the same time, the global 3G market has entered into a stage of rapid development. Despite the fact that the financial crisis in the second half of 2008 has slowed the deployment of 3G network deployment, the overall 3G users continues to maintain a rapid growth, and the range of 3G services and applications continues to expand, which are particularly promoted by the increasingly widespread application of 3G-enhanced technologies. CATR of MIIT has made a tracking study on the development of the global 3G market in 2009-2010, and through the overview of the industrial environment in global 3G market in terms of regulatory environment, technology evolution and market applications. The report just released analyzed the development process and trends of global 3G networks, users, operations and terminals, and focused on the competition among Chinese operators in 3G market. The competitive strategies of the three operators have been analyzed so as to determine incoming trends of China's 3G market.
