The new generation of artificial intelligence is developing rapidly and has increasingly become the driving force for the leap in productivity. The 14th five year plan for digital economy development issued by the State Council this year proposes to take the deep integration of digital technology and the real economy as the main line, constantly strengthen, optimize and expand China's digital economy, and provide strong support for building a digital China. Focusing on the deep integration of artificial intelligence and real economy, four experts are invited to discuss this issue. Artificial intelligence has a profound impact on economic and social development. What is artificial intelligence? What is the development and application trend of artificial intelligence in the world? Mei Jianping (deputy director of the High Tech Department of the Ministry of science and Technology): after more than 60 years of accumulation and evolution, artificial intelligence (AI) has made historic progress driven by technology and market, showing new characteristics such as deep learning, cross-border integration, human-machine collaboration, group intelligence opening, and autonomous control. Relevant technologies continue to penetrate into the real economy, and are facing economic development, social progress Global governance has had a significant and far-reaching impact. It is generally believed in the industry that artificial intelligence mainly studies theories, methods, technologies and application systems that simulate, extend and expand human intelligence. Its core content is models and algorithms, and its extension includes software and hardware such as sensing, computing and action mechanisms that support models and algorithms, so as to form an intelligent system that can see, listen, speak, think, learn and act. At present, artificial intelligence has the following main characteristics. First, from perceptual intelligence to cognitive intelligence. The development of artificial intelligence has gone through three stages: Computational Intelligence (able to store and calculate), perceptual intelligence (able to listen, speak, recognize and see), and cognitive intelligence (able to understand and think). The artificial intelligence system shall have the ability to perceive the external environment and learn, and shall be adaptive, flexible and expandable. Deep learning has become the mainstream paradigm in the field of artificial intelligence, leading to a new round of artificial intelligence development. At the same time, brain like intelligence is poised to develop, and quantum intelligence is accelerating; In terms of intelligence, the development of global artificial intelligence is gradually changing from weak to strong. The data-driven perceptual intelligence is increasingly mature, and the knowledge driven cognitive intelligence is gradually breaking through. Second, it shows a strong spillover driving effect. Artificial intelligence can reconstruct all links of economic activities such as production, distribution, exchange and consumption, realize major technological innovation and product innovation by using artificial intelligence, improve the management level, production efficiency and product quality of application subjects, and promote industrial intelligent upgrading. For example, intelligent robots and flexible intelligent manufacturing technologies have promoted the transformation of commodity manufacturing mode from assembly line standardized manufacturing to large-scale customized product supply; Accelerate the process optimization and reengineering of aviation, wharf, storage and other production links through intelligent algorithms, save equipment, fuel and manpower, realize the upgrading of production lines and efficiency, and reshape the competitiveness of enterprises. Third, it has dual characteristics of technology and society. Artificial intelligence is a disruptive technology with wide and far-reaching influence. On the one hand, technological breakthroughs will create new products and new functions, thus opening up new space and creating new values; On the other hand, artificial intelligence has a certain degree of autonomy and can make decisions and analysis, so it has
