Objectively speaking, China’s science and technology did not begin to develop rapidly until the 1990s. However, since World War II, the United States has essentially confirmed its dominance in science and technology. After the collapse of the Soviet Union, the United States became the only superpower on earth. Its technological strength can be said to have completely crushed all other countries. Generally speaking, China lags behind the United States in science and technology, but China has the advantage of being a latecomer, so in many aspects China has caught up. China's leading technology in the world can be summarized as follows:
1. Supercomputer
Among the 500 fastest supercomputers in the world, China has 219 and the United States has 116 . Although American supercomputers finally took back the throne of fastest computer recently. But China will release a new generation of multi-trillion supercomputers next year, and the United States will not release it until 2021 at the earliest.
2. UHV transmission technology
China has established the world’s first ultra-high voltage DC and AC lines, which can effectively transport power resources from the western region to the eastern region. The United States does not have such projects and technologies.
3. High-speed rail technology
China’s high-speed rail technology is unique in the world. It has exploded in the United States in terms of speed, route length and complexity. America's railroads are still in the days of our "K" bullet trains.
4. Advanced coal technology
China has developed supercritical coal-fired power plant and ultra-supercritical coal-fired power plant technologies, which can effectively reduce pollutant emissions during the coal burning process.
5. Nuclear energy technology
China has more than 30 nuclear power projects under construction, more than the rest of the world combined. In addition, China and the United States are also world leaders in developing fourth-generation nuclear power technology.
6. New energy vehicles
China is a world leader in the research of electric vehicles, hydrogen vehicles and hybrid vehicles. Especially in the field of electric vehicles, electric vehicles that can run 800 kilometers on a single charge have been developed. It plans to produce 5 million new energy vehicles by 2020.
7.5G technology
Chinese communication technology companies represented by Huawei have the most 5G technology patents. China's 5G has already begun commercial applications, while the United States may still be discussing changing the 4G to 5G logo.
