Rice cookers, microwave ovens, dishwashers ... these real household appliances really make people's lives convenient, fast and hygienic, and people not only save time. But who can deny that these household appliances, even a small razor, are not technological products? At present, technology has penetrated into the daily life of everyone in the world. People can't live without these scientific and technological products. To put it alarmingly, if there are no scientific and technological products, we will return to primitive society again. Without scientific and technological products, we can't enjoy today's comfortable life; Without scientific and technological products, our future life will not become rich and colorful, which makes us have high hopes.

There is no doubt that the greatest scientific and technological product of mankind in the 20th century is the computer. Since the birth of the first computer in the world, in just a few decades, people's lives have undergone unprecedented changes. The sign of this change is first reflected in people's conversations, from "Have you eaten?" Go to "Did you buy a computer?" From "Did you buy it from a computer?" Go to "Are you online?" Even to "I just ordered some books online and will arrive soon" and so on, human beings have improved their quality of life and changed their production, lifestyle and even way of thinking because of computers. "Internet" is making people, especially young people, truly experience "technological life".

"Science and technology are productive forces, and they are the primary productive forces." Comrade Deng Xiaoping's assertion brilliantly illustrates the prominent role of scientific and technological progress in economic development and social progress. Science and technology are the most active and active factors in productive forces. In the whole history of human civilization, science and technology have always played a very important role. Any major leap in human society is a major breakthrough in scientific and technological progress. In particular, successive industrial and technological revolutions have made a great leap in human understanding of the objective world and revolutionized the ability to transform the world. Since the first industrial revolution, social productive forces have increased by 100 times. In the 20th century, due to the rapid progress of science and technology and the substantial improvement of productivity, the global economic scale increased by more than 20 times, from 1 trillion dollars to nearly 30 trillion dollars. In the high growth of global economy, the contribution rate of scientific and technological progress has increased from about 5% at the beginning of this century to 60-70%. Scientific and technological progress has become the source of a country's prosperity and the main driving force and source of human civilization. In particular, modern high technology, as the commanding height of cross-century competition, as the locomotive of history in the new period and as a powerful lever for future economic growth, social development and civilization progress, has attracted the attention of all mankind. The degree of economic development depends more and more on the degree of scientific and technological progress.

The content of science and technology is very extensive, whether it is military, biological or aerospace, science and technology should be used. Technology has been integrated into life and enriched it. In transportation, family, education and business, technology has brought people a convenience. The invention of traffic lights is a kind of traffic civilization, which not only brings convenience to people, but also is a kind of safety, so that people are no longer afraid of the traffic coming and going. Nowadays, every household is using electrical appliances, all of which are scientific and technological products, such as microwave ovens and rice cookers, which are developed through scientific research and development to facilitate the public. In education, the most remarkable representative work of science and technology is the network. Nowadays, online education is popular, and children can get explanations from professional teachers who are far away from home without going out. Surfing the internet can also enrich knowledge, and reduce such a big world to a small computer through the network to understand what is happening around the world. In business, technology brings huge economic benefits. Microsoft President Bill? Gates, who invented the Windows system, is popular all over the world, and now it is used by every household. This invention made him the richest man in the world 10. So some economists once said, "He has that money because everyone is working for Bill." .

At present, driven by the wave of new technological revolution, the future of mankind is about to enter a knowledge-based economy society, and some developed countries such as the United States are entering a knowledge-based economy society. According to experts' research and analysis, China is currently in the embryonic stage of knowledge economy society. What is certain is that the 2 1 century, that is, the future of mankind, will usher in a brand-new era of knowledge economy. According to the explanation of the Organization for Economic Cooperation and Development, knowledge economy is an economy with modern science and technology as its core and based on the production, storage, use and consumption of knowledge and information. Although knowledge is indispensable to create wealth in the era of agricultural economy and industrial economy, knowledge economy regards knowledge with modern science and technology as the most important economic resource and the most important factor of production. It can be said that knowledge economy typically reflects the trend of the integration of science and technology and economy. In the era of knowledge economy, the relationship between scientific and technological progress and economic development will be closer, and economic development will mainly rely on scientific and technological progress. In fact, many people, including the famous scientist Qian Xuesen, advocate that "knowledge economy" should be called "science and technology economy" more accurately. Science and technology competition, especially high-tech competition, will be the core content of future international competition. In the State of the Union address published in February 1997, US President Bill Clinton emphasized that "powerful scientific and technological forces must be driven", and in the documents published by the US government, he also pointed out that "science is an infinite resource, and technology is the foundation of future economic growth and national prosperity".
