At present, the representative fields of hard science and technology: photoelectric chip, artificial intelligence, aerospace, biotechnology, information technology, new materials, new energy, intelligent manufacturing and so on. The concept of "hard technology" was put forward on 20 10 by Miller, Ph.D. in optics of Xi Institute of Optics and Mechanics, Chinese Academy of Sciences and founding partner of Zhongke Chuangxing. Miller put forward the concept of "hard technology", hoping to create a new concept, change the current situation that China used to "emphasize" mode innovation and "ignore" technology innovation, and guide people to pay attention to those key core original technologies that can really promote economic development and need long-term R&D investment and continuous accumulation, so as to unite the whole society to grasp the driving force of the bottom of the economy and support China's economic development from following to leading in the new era.
