Date of issue:[2020-08-17]     Click through rate:    

The development of modern science and technology represented by information technology puts forward higher and newer requirements for the equipment manufacturing industry, which highlights the irreplaceable basic role of the machinery and equipment manufacturing industry as a carrier of high-tech industrialization in promoting the technological progress and industrial upgrading of the whole society. As the driving force of the national economic growth and technological upgrading, the mechanical industry will make common progress with the development of high-tech and emerging industries, and fully reflect the general trend and characteristics of the times of the development of advanced manufacturing technology in the direction of intelligence, flexibility, networking, precision, green and globalization.

Status based. Developed countries attach importance to the development of equipment manufacturing industry, not only because of its proportion in the domestic industry, accumulation, employment, contribution are in the forefront, but also lies in the equipment manufacturing industry provides important material technology for the development and production of new technologies and new products, and is an indispensable strategic industry for economic upgrading. Even the industrialized countries striding into "information society" attach great importance to the development of machinery manufacturing industry.

High tech products. Advanced equipment manufacturing industry is an important part of high-tech and an important support to promote the upgrading and development of related industries. In the 1990s, with the application of information equipment technology, industrial automation technology, numerical control processing technology, robot technology, advanced power generation and transmission and distribution technology, power electronic technology, new material technology and new biological, environmental protection equipment technology and other contemporary high-tech achievements, mechanical products have been continuously high-tech, and their high-tech content has become the key to win the market competition Key.

Personalized service. In order to meet the uncertainty of market demand and personalized user requirements, advanced manufacturing enterprises continue to absorb all kinds of high-tech and modern management technology and other information, and comprehensively apply it to the whole process of product design, production, management, sales, use, service and even recycling, so as to achieve high-quality, efficient, low-consumption, clean, sensitive and flexible production.

Large scale operation. On the one hand, large-scale production makes the technological innovation and market leading role of monopoly multinational companies increasingly strengthened. For example, in the field of automobile industry, there are 6 enterprise groups with an annual output of more than 4 million vehicles, accounting for more than 80% of the world's automobile output; in the field of electric power equipment, the world's top three companies control 70% of the global large-scale power equipment market. On the other hand, while the major multinational corporations continue to combine and restructure to expand their competitive strength, they have to shrink their front lines and peel off their non main businesses in order to improve their system capability, personalized and diversified market adaptability. As the premise and condition of large-scale production, the "midfield industry" which produces high-level components and supporting products has developed rapidly, the socialized production service system has been constantly improved, and the pace of internationalization of the industry has been accelerating.
