New characteristics: High technology is developing rapidly, the knowledge economy is emerging, the role of science and technology in promoting economic development is becoming more and more obvious, and the process of globalization is accelerating.

Strategic decision-making: Implement the strategy of rejuvenating the country through science and education.

The "high" of high technology is relative to conventional technology and traditional technology, so it is not an immutable concept, but has a historical, developmental, and dynamic nature. Today's high technology will become tomorrow's conventional technology and traditional technology. Some estimate that only 1% of the technology and knowledge that people use today will be 50% in 60-60 years, and 99% will be obsolete.

From the perspective of the development of high technology in various countries in the world, high technology is not a single technology, but a new technology group at the forefront of science, technology, and engineering. The various components of this group influence each other, complement each other, and promote each other. At the same time, due to the high technology is with high.

The technology industry is linked together, so it is a production system that integrates science, technology and production, and is strongly promoted by the market.

In addition, high-tech is also different from the so-called "accumulation of experience" in the general sense of science and technology. It is not an accumulation of experience, but a technology based on scientific discoveries or creations.

High-tech is not mysterious, it's all around us. It is human-centered and a manifestation of human ingenuity. The wave of high-tech is impacting and changing all areas of human social life, and it is also impacting and shaking everyone's heart.

High-tech pays attention to everyone, and everyone pays attention to high-tech.

(1) Material 1 shows that science and technology are the primary productive forces; Material 2 shows that innovation is the soul of a nation's prosperity and development, and there is still a big gap between China's science and technology and comprehensive national strength compared with developed countries on the whole.

2) Innovation is the soul of a nation and an inexhaustible driving force for the prosperity of a country. The essence of science and technology is innovation. If China wants to truly narrow the gap with developed countries and catch up with and surpass developed countries, the key is to rely on innovation.

This is because only by putting the basis of scientific and technological progress on enhancing the ability of independent innovation and sustained innovation can we realize the leapfrog development of science and technology in our country and truly grasp the initiative in development. Without innovation, we must be controlled by others. Without innovation, it is impossible to catch up with and surpass the developed countries.
