This paper discusses the influence of social informatization on life.

In the 20th century, mankind has made a series of brilliant achievements in science and technology. It has also formed high-tech fields and industries such as electronic information, biotechnology, new material technology, aerospace and atomic energy, among which electronic information technology has the widest, largest and longest impact on the economy and society. For more than 40 years, driven by the development of microelectronics and digital technology, electronic information equipment has improved its performance at a high speed and reduced its volume energy consumption, on the other hand, it has reduced its price at an alarming rate, creating good technical conditions and economic possibilities for the wide application of information technology. With the rapid rise of the Internet in the world in the 1980s and 1990s, it has had a far-reaching impact on economic activities and human life style. By the end of 2000, the Internet has connected more than 6,543.8+0 million networks, 6,543.8+0 million hosts and 500 million users around the world, forming a global information channel for the development and utilization of information resources, entering all aspects of human social life, having a great impact on politics, economy, military affairs, science and technology, culture and society, and opening the prelude to the information economy era.

First, the main development trend of information technology

The remarkable achievements in the popularization and application of information technology have prompted countries all over the world to devote themselves to informatization construction, and the huge demand for informatization has promoted the rapid development of information technology. At present, the general trend of information technology development is to pay attention to the development and application of internet technology, from the typical technology-driven development model to the combination of technology-driven and application-driven model.

Microelectronics technology and software technology are the core of information technology. The integration, computing power and cost performance of integrated circuits continue to increase geometrically at the rate of doubling every 18 months, which supports the information technology to reach an unprecedented level. Now, each chip contains hundreds of millions of components, which constitutes a "system on a chip" (SOC), which blurs the boundary between the whole machine and components, greatly improves the function of information equipment, and promotes the development of the whole machine in the direction of light, small, thin and low power consumption. Software technology has changed from computer-centric to network-centric. The mutual penetration of software and integrated circuit design makes the chip become "solidified software", further consolidating the core position of software. With the rapid development of software technology, more and more functions are realized by software, "hardware softening" has become a trend, and technical fields such as "software radio" and "soft switching" have appeared. The development of embedded software makes the software go out of the traditional computer field and promotes the intelligence of many industrial products and civil products. Software technology has become the core technology to promote informatization.

Triple play and broadband are the general direction of network technology development. The integration of telephone network, cable TV network and computer network means that they are consistent in network technology and cover each other in business content on the basis of digitalization. Telephone network and TV network should be in line with internet technology in technology, and their basic characteristics are IP protocol and packet switching technology; In business, it is necessary to develop from voice-based or one-way transmission to interactive multimedia data service. The integration of three networks can not be simply understood as the integration of three networks, but it does break the original industry boundaries and will lead to industrial restructuring and policy adjustment. With the rapid increase of data traffic on the Internet, especially the increase of multimedia information, the demand for network bandwidth is also increasing. Increasing bandwidth is the theme of network technology development for a long time. In WAN and MAN, the all-optical network technology represented by DWDM attracts people's attention and promotes the development of optical information technology. Various schemes of broadband access network technology have launched fierce competition, and it is still difficult to know who will win. Wireless broadband access technology and mobile internet technology based on the third generation mobile communication technology are developing towards the goal of information personalization.

Internet application development is also a continuous hot spot. On the one hand, TV sets, mobile phones, personal digital assistants (PDA) and other household appliances and personal information equipment are all developing in the direction of network terminal equipment, which forms the diversity and personalization of network terminal equipment and breaks the situation that computers are online. On the other hand, e-commerce, e-government, distance education, electronic media and online entertainment technologies are becoming more and more mature, and the requirements for users' professional knowledge and economic input are decreasing; The emergence of technologies such as Internet data center (IDC) and portal service and the formation of service system constitute an increasingly perfect social service system using the Internet, which enables information technology to enter all fields of social production and life more and more widely, thus promoting the formation of network economy.

Second, the information industry has become the engine of economic growth.

With the rapid progress of world informatization, the demand for information in the world is growing rapidly, and information products and services are essential for all countries, regions, enterprises, units, families and individuals. Information technology has become the cornerstone of economic activities and social life. In this case, the information industry has become a strategic industrial sector that all countries in the world, especially developed countries, compete for investment and focus on development. In the past 10 years, the global information equipment manufacturing and service industry grew twice as fast as the corresponding gross national product (GNP), and became the key industries to stimulate economic growth. Among them, in the past 10 years of sustained and rapid growth, the average annual GDP growth was 3.6%, while the contribution of electronic information industry to GDP growth was 1.4 percentage points. It is no exaggeration to say that the sustained growth of American economy benefits from the support of information technology and the promotion of information industry. After years of rapid growth, the information industry itself has become one of the largest industries in the world. In the mid-1990s, the growth of information economy in some developed countries exceeded 50% of GNP, while that in the United States exceeded 75%. In 2000, the output value of global information product manufacturing industry reached 654.38+0.5 trillion US dollars, which became an important pillar industry of the world economy.

During the Ninth Five-Year Plan period, China's information industry developed at three times the speed of the national economy, the sales of main products increased rapidly, the structural adjustment achieved initial results, some key technologies made breakthroughs, and the industrial scale ranked fourth in the world. By the end of 2000, the total output value of information product manufacturing industry reached 654.38+0 billion yuan, and the sales revenue reached 580 billion yuan, making it the first pillar industry of the national economy. The added value of the information industry accounts for 4% of the national GDP, and the export value of electronic products accounts for about 1/5 of the total national exports, and the contribution rate of the information industry to the national economy has increased significantly.

Third, information technology promotes the technological upgrading of traditional industries.

Information technology represents the development direction of advanced productive forces today. The wide application of information technology makes information, an important factor of production and strategic resource, play a role, enabling people to optimize resource allocation more efficiently, thus promoting the continuous upgrading of traditional industries and improving social labor productivity and social operation efficiency. As far as traditional industrial enterprises are concerned, information technology promotes enterprise upgrading at the following levels: 1. It is an important direction to realize product upgrading to embed information technology into traditional mechanical instrument products and promote the "intelligence" and "networking" of products. This work is often called "mechatronics". 2. Computer aided design technology and network design technology can significantly improve the technological innovation ability of enterprises; 3. Using computer-aided manufacturing technology or industrial process control technology to realize automatic control of product manufacturing process can obviously improve production efficiency, product quality and yield; 4, the use of information systems to achieve scientific management of enterprises, unified integration and deployment of human, material and financial resources of enterprises, to achieve overall optimization. 5. Using the Internet to carry out e-commerce, manage supply chain and customer relationship, and promote the upgrading of business philosophy and mode can improve the market competitiveness and economic benefits of enterprises. Information technology represented by the Internet is also a powerful weapon to promote agricultural modernization and the development of the tertiary industry.

Fourth, the labor structure is undergoing tremendous changes.

With the development and utilization of information resources, people's employment structure is changing from agricultural population and industrial population to information-related work. Take the United States as an example From 65438 to 0956, the number of "white-collar workers" in the United States exceeded that of "blue-collar workers" for the first time. From 65438 to 0980, the employment ratio in the United States was: agriculture, forestry and fisheries accounted for 3.38% of the total employment, mining and construction accounted for 7.23%, manufacturing accounted for 22.09%, and service accounted for 67.2%. This trend has further developed. By 1997, agriculture, forestry and fisheries accounted for 2.63% of the total employment, mining and construction accounted for 6.88%, manufacturing accounted for 16.08%, and service industry expanded to 73.34%. In the service industry, except for a few traditional service industries, most of them are engaged in occupations related to information processing and information services. For this trend, American scholars concluded: "From farmers to workers to employees, this is a brief history of the United States." "We produce a lot of information now, just like we used to produce a lot of cars."

Verb (abbreviation of verb) Information technology has promoted the progress of human civilization.

The wide application of information technology in the world not only profoundly affects the economic structure and efficiency, but also profoundly affects the social culture and spiritual civilization as the representative of advanced productive forces.

Information technology has caused profound changes in traditional education methods. The diversity of computer simulation technology, multimedia technology, virtual reality technology, distance education technology and information carriers enables learners to overcome the obstacles of time and space and arrange their own learning time and speed more actively. In particular, distance education with the help of the Internet will open up a global knowledge dissemination channel and realize the mutual dialogue and exchange between learners and instructors in different regions, which will not only greatly improve the efficiency of education, but also provide learners with a relaxed and rich learning environment. The development of distance education will trigger a revolution in the field of traditional education and promote the general improvement of human knowledge.

Internet has become an indispensable tool for scientific research and technological development. With more than 600 large libraries, more than 400 document repositories and 1 10,000 information sources, the Internet has become a treasure house for researchers to access and obtain the latest scientific and technological trends at any time, greatly saving the time and cost of consulting documents. The rapidity and interactivity of information transmission on the Internet enable researchers anywhere in the world to become research partners, conduct real-time discussions and collaborative research online, and even use online hosts and software resources to complete their own research work.

Information network provides a more convenient channel for the spread of various ideas and cultures. A large amount of information permeates every corner of society through the network and becomes an important means of cultural communication today. Various forms of electronic publishing, such as CD-ROM, disk and online publishing, have broken the situation that paper media dominated the world in the past. The application of multimedia technology and the adoption of interactive interface have opened up broad prospects for the popularization of culture, art and technology. New information media, such as the Internet, provide new possibilities for the inheritance and dissemination of excellent cultures of all ethnic groups and for the exchange and blending of cultures of all ethnic groups. The network is changing the way of communication between people, changing people's working methods and lifestyles, which will inevitably have a far-reaching impact on the development of culture, and a new advanced culture that adapts to the network era and information economy will gradually take shape.
