By the end of 2005, China boasted 100,000 MB export broadband capacity, 700,000 websites, 1.09 million China-coded domain names, 49.5 million computers with Internet access, and 111 million Internet users, ranking second in the world. A host of web-based services have thrived, for example network education, online banking, E-commerce, Internet advertising, news, video, and charged postal services, Internet Protocol (IP) telephone, SMS text-messaging, online recruitment, information services and games.
Working on the basis of results from the Public Key Infrastructure (PKI) project in the 863 Program, three years' efforts by over 300 scientists completed the security and application platform of the government infranet. After breakthroughs in many key code technologies, a data security and network credit system for government affairs has basically been established, satisfying demands for inter-departmental, multi-application communication, resource sharing and application integration.
The information industry has become a mainstay of China's economy. In 2005, the added value of China's information industry, which is the world's third largest, stood at 1,130 billion yuan. Output values, sales and profits of electronic and telecoms manufacturing all outstripped those of traditional industries, making the greatest contribution to national economic growth.
Posts and telecommunications are important elements of the information industry. After decades of construction and development, a national postal network has taken shape, with Beijing and other major cities as the centers, linking all cities and rural areas. As for the telecommunications network, a basic transmission network featuring large capacity and high speed is now in place. It covers the whole country, with optical cable as the mainstay, supplemented by satellite and digital microwave systems. Every provincial or autonomous regional capital, with the exception of the Tibetan capital Lhasa, is connected by at least two optical cables. In economically advanced coastal and inland areas, optical cable has reached villages, towns, urban communities, and high-rise buildings, thus becoming the main technology for transmitting information. Meanwhile, China has participated in the construction of a number of international land and sea-bed optical cables, such as the China-Japan, China-ROK, and Asia-Europe sea cables, as well as Asia-Europe and China-Russia land optical cables. China initiated the construction of the 27,000-km Asia-Europe optical cable, the world's longest land optical cable system, passing through 20 countries in its journey from Shanghai to Frankfurt in Germany. So far, China has established telecommunication business relations with more than 200 countries and regions in the world.
By the end of 2005, China has had 743.86 million telephone subscribers, 350.43 million fixed lines and 393.43 million mobile phone subscribers, constituting the world's largest telephone network. Since China started mobile telecommunication business in 1987, the mobile network now has covered all urban and rural areas, and international roaming service exists with over 200 countries and regions all over the world.
Now, the public data telecommunications network has taken initial shape, with group data exchange, digital data, computer Internet, multimedia telecoms, and frame relay networks as the mainstay. Covering over 90 percent of counties and cities in China, it is among largest public data telecommunications networks in the world. Radio and TV networks continue to develop rapidly, and the number of radio and TV users exceeded 200 million by the end of 2005, almost all villages in China having access to radio and TV broadcasting.
