The production of high-frequency welding machines is developing in depth and breadth, and more people with knowledge are needed, which in turn encourages people to receive education and master more knowledge. This makes knowledge accumulate and more and more people have knowledge. Such a snowball expansion has resulted in an increasing number of knowledge groups. Science and technology have the characteristics of accelerating development. The development is faster and faster, and the accumulation of knowledge is getting deeper and deeper. Those who master the knowledge combine the accumulated knowledge of high-frequency welding machines and newly created knowledge.
Socialized mass production requires collecting information, forecasting and planning before giving birth, which are also intermediate links. The increase in intermediate links has led to intensified occupational differentiation, which has led to a large increase in the number of personnel in the service industry. In the service industry, the number of manual workers (such as commerce and transportation workers) has increased at first, followed by mental workers (education, scientific research, design, The increase in information and planning personnel, and the increase in mental workers, is not only the development of productivity, but also the accumulation of culture. Human beings transform nature into depth and breadth, and continue to accumulate knowledge, so the accumulated knowledge of mankind is increasing day by day. In the contemporary world, information has exploded. Just as more raw materials will produce more products, more information will produce more new knowledge, so that all areas of society can use new knowledge to change the face.
At the same time, the production of high-frequency welding machines is developing in depth and breadth, and more people with knowledge are needed, which in turn encourages people to receive education and master more knowledge. This makes knowledge accumulate and more and more people have knowledge. Such a snowball expansion has resulted in an increasing number of knowledge groups. Science and technology have the characteristics of accelerating development. The development is faster and faster, and the accumulation of knowledge is getting deeper and deeper. The people who master the knowledge combine the accumulated knowledge of the high-frequency welding machine and the newly created knowledge. The industry of applying knowledge is rapidly expanding and forming the knowledge Based on the knowledge economy, the productivity structure is the coordinate system. The industrial structure runs along the track of agricultural economy (including special industries), industrial economy, and knowledge economy (including information economy). Knowledge economy is a latecomer and a symbol of contemporary advanced production. In terms of industry classification, there are three types of industry classification methods, which call the production of raw materials the primary industry; the manufacturing industry is called the secondary industry, and the others are classified as the tertiary industry.
The business and life service industries in the tertiary industry existed before the high-frequency welding machine industry, and the information, scientific research, and design industries in the tertiary industry emerged only after the industry was highly developed. In this way, the three types of industries are divided The law cannot accurately describe the development track of the industry. However, new service industries such as information, scientific research, and design are all knowledge industries, so the concept of knowledge economy can best illustrate the track of industrial development. Productivity function: From the survival type to the harmonious type, in previous studies of productivity, two coordinate systems were basically selected: one is the element, which refers to such elements as labor, tools, and labor objects; the other is the structure, mainly the industrial structure. As for the function of productivity, people pay little attention to the development of productivity elements and structure. It is generally believed that science and technology elements and knowledge economy represent contemporary advanced productivity, and the development history and future development trends of productivity function are worth studying. According to the principle of system theory, structure determines function, and the structure determines the function. This is universally applicable to natural objects, and is most fully reflected in the fields of physics, chemistry, and biology. The productivity system is more complicated.
