The role of manufacturing informatization in promoting the development of machinery industry is generally reflected in four aspects: first, in terms of products, through the integration of information technology and advanced manufacturing technology, traditional mechanical products are integrated with information, computers, lasers and other high-tech, making them become electromechanical integrated products and modern technology integrated products, thus improving the function and intelligence level of products to meet the requirements of the information age for mechanical products; Second, the automation and intelligence of the design and manufacturing process greatly shortens the design cycle, improves the design success rate, reduces the design cost, improves the market response speed, improves the automation and intelligence of the manufacturing process, improves the product quality and consistency, and reduces the labor intensity; Third, at the enterprise level, it integrates all kinds of information of enterprises to form resource sharing, which improves the management level, work efficiency and economic benefits of enterprises, thus improving the market competitiveness of enterprises; Fourthly, the information interconnection among enterprises has been realized, so that the resources of different enterprises can be shared, which has greatly changed the organization, research and development, production and management mode of the machinery industry, reduced redundant construction and waste of resources, adapted to the requirements of economic globalization and networking, and improved the overall competitiveness of the industry.

Informatization makes it possible for the enterprise organization structure of manufacturing industry to change from the original pyramid organization with linear function system to a flat network organization. Under the planned economy system, the manufacturing enterprise is basically an economic organization only responsible for production, and it is a production mode of "big and complete" and "small and complete". Enterprises even undertake the function of running society, with weak R&D ability, weak business and sales links and relatively large processing capacity. The organizational structure is like an olive, with two small ends and a big middle. Under the market economy system, enterprises become the main body of the market, so they must strengthen research and development and sales, and the processing links in the middle can make full use of the processing capacity of society. The organizational structure of an enterprise is also like a dumbbell, strong at both ends and refined in the middle. Informatization makes it possible for enterprises to change their organizational structure from "olive" to "dumbbell".

Informatization has also fundamentally changed the production mode of manufacturing enterprises. Lean production, agile manufacturing, concurrent engineering, mass customization and so on are all the results of informationization. E-commerce, supply chain management, networked manufacturing, etc. They are all inseparable from information technology, and it is these new modes of production organization that come with informationization that make the competitiveness of manufacturing industry constantly improve and climb to a new height, and can continuously meet the individual needs of users.
