The key core technology is the most important weapon of the country, and it is of great significance to promote the high-quality development of the economy and ensure national security of China. The independent research and development strength of the Chinese enterprises is like a surging torrent, calmly and powerfully breaking the foreign technology blockade, and quietly promoting China’s transformation from a big manufacturing power to a strong manufacturing power. China has completely got rid of the long-term dependence on imports of many advanced technologies and products including large and heavy-duty bevel gear pairs. While striving to catch up with foreign advanced technologies, Chinese scientists and engineers are also using their brains to find a new path of their own.

What new changes can these self-developed technologies bring to life? After all, the ultimate goal of scientific invention is to improve human life. For example, the hydrogen hybrid power system developed by Shanghai Woneng Environmental Protection Technology Co., Ltd. (上海沃能环保科技有限公司) can effectively save fuel by 25% and reduce carbon dioxide emissions.

Major breakthroughs have been made recently in the development of key technical equipment for deep water oil and gas development, which is of great significance to building an independent and controllable offshore oil and gas equipment system and ensuring national energy security. The successful development and application of the domestic deep water subsea production system can enable the effective development of many deep water marginal oil and gas reservoirs that did not have economic benefits in the past. The underwater production system needs to be stably produced on the seabed at a depth of more than 500 meters for more than 20 years, which requires extremely high equipment design capabilities and construction technology. After long-term technical research, the R&D team has successfully mastered a number of core technologies such as the overall design of the underwater production system, localized manufacturing of core components, assembly technology and offshore installation. This achievement is of positive significance for driving the development of offshore oil and gas equipment related industries in China.

The new-generation thinner foldable screen flexible display made by BOE Technology Group Co., Ltd. (京东方) is only 1/3 of the thickness of A4 paper, and a 0.03 mm thin screen can accommodate 42 layers of laminate structure.

It is precisely because of its insistence on independent research and development and innovative development that XGIMI (极米科技) has broken the monopoly of foreign brands in the Chinese projector market in the field of smart projection and has ranked first in the Chinese projector market for four consecutive years.

FiberHome Telecommunication Technologies Co., Ltd (烽火通信科技股份有限公司) is a world leader in R&D and production in the field of optical communications and has made 6.75 billion and then 30 billion simultaneous calls on one optical fiber.

There are frequent reports of good news in frontier fields such as deep space, deep sea and deep earth. Forging presses, shield machines, generators and other national heavyweights lead innovation, 5G, high-speed rail, smart phones, new energy vehicles and other industries lead the world. Behind innovation, the self-improvement figure of more and more companies is emerging everywhere.

The average age of the research and development teams is only 35 years old. From the design review to the optimization of the process parameters, the complete set of equipment is jointly participated by the R&D personnel and the production line workers.

The number of high-tech enterprises in China increased from 49,000 to 330,000. The scientific and technological investment of enterprises has been continuously increased. At present, the R&D investment of enterprises in the whole society has reached more than 76%. Nearly 80% of the national key R&D plans are set up in 2021, with companies taking the lead or participating.

ALG Aluminium lnc. (广西南南铝加工) and Northeastern University, Guangxi Advanced Aluminum Processing Innovation Center and the other units formed a project team, jointly developed major national short-board equipment, and successively overcome a series of technical problems. In April 2020, the first set of roller hearth furnace project of Nannan Aluminum Processing was officially completed. In July 2022, the first set of air cushion furnace project of ALG Aluminium lnc. was officially completed, realizing the complete autonomy and localization of the core components of high-end aluminum equipment effectively promoting the solution of aluminum processing heat treatment equipment in China.

At Yangtze Optical Fiber and Cable Joint Stock Limited Company, the drawing length of a single optical fiber preform has been extended from 7,000 kilometers to 10,000 kilometers.

In summary, the Chinese actively seize the key variable of technological innovation, the commanding heights of technological competition and future development, and strive to achieve independent and controllable key core technologies. They will surely be able to firmly grasp the initiative of innovation and development in their own hands.

Technology is always dynamically changing like the fashion products. No technology can be kept secrets forever. New discoveries will make the existing ones second best or even worthless quickly. China does not have to worry about getting the new foreign technology because the Chinese can develop their own.
