We must master the key core technologies of digitalization and firmly grasp the development of digital economy in our own hands.

To firmly grasp the autonomy of developing digital economy in our own hands, we must hold the bull's nose of independent innovation of digital key core technologies.

Throughout the history of world civilization and social development, mankind has experienced agricultural revolution, industrial revolution and information revolution, and every scientific and technological revolution and industrial change has brought a qualitative leap to productivity.

In recent years, technologies such as the Internet, big data, cloud computing, artificial intelligence and blockchain have accelerated innovation and are increasingly integrated into the whole process of economic and social development. The digital economy is developing at an unprecedented speed, with wide radiation and deep influence. It is becoming a key force to reorganize the global factor resources, reshape the global economic pattern and change the global competition pattern. Human society is entering a new historical stage marked by digital productivity.

Developing digital economy is a strategic choice to grasp the new opportunities of the new round of scientific and technological revolution and industrial transformation. In this context, major economies in the world have introduced medium-and long-term digital development strategies, trying to build a digital-driven economic system based on their respective advantages in information and technology. Whether we can firmly hold the autonomy of developing digital economy in our own hands is related to whether we can seize the opportunity of a new round of scientific and technological revolution and industrial transformation and win the initiative of future development and international competition.

To fight the key core technologies, we must hold the "bull nose" of independent innovation. In recent years, economic globalization has met with counter-current, and the COVID-19 epidemic has intensified the trend of anti-globalization. Some western countries, led by the United States, suppressed China's industry and technology in an all-round way, and the global industrial chain and supply chain were partially broken.

Key core technologies can't be bought, can't be bought, and can't be discussed. To firmly grasp the autonomy of developing digital economy in our own hands, we must unswervingly follow the road of independent innovation with China characteristics, be brave in leaping over and tracking innovation, break through subversive technological innovation, reshape the competitive pattern of industrial chain and supply chain, and continuously enhance viability, competitiveness, development and sustainability.
