Description:

Driven by a new round of scientific and technological revolution, information technology is entering an era of rapid and accelerated breakthroughs. In order to seize the historical opportunity brought by the development of information technology, we must grasp the development trend of cutting-edge technology in the field of information technology. Based on tracking and collecting the information technologies, expert judgment and system analysis, this chapter demonstrates the overall distribution of information technology and the distribution of technology in various fields. The results show that most of the cutting-edge information technology concerned at home and abroad is between basic technology and scene technology, more than half of the technology has entered the practical application stage, there are still gaps between China's R&D level and the international advanced level, most of the technology has not reached a comparable level, but in some specific fields began to show a leading trend. In addition, based on the expert rating of the technology on its cutting-edge, application and importance, this paper identifies the cutting-edge technologies in various fields that need to be focused on, such as the Photo-lithography technology, Next generation wireless network technology, Generative AI technology, Quantum encryption technology, Integrated circuit design technology, Quantum computing system, Non-contact gesture recognition technology and so on. Those work lay the foundation for the development of information technology and digital industry in China.
