In response to the new requirements for design posed by the digital economic tides, 2022 Beijing Design Week is themed on "Number-Real Mutual Generation" to discuss from the perspective of design the due relations between the digital world and the real world, and establish the methodology of design supporting the benign development of digital economy. "Alternation", a botanical concept, is a kind of phyllotaxis, which means that the leaves grow alternately on both sides of the stem, and are in overall symmetry but not one-to-one correspondence, and they intergrow upwards. The "Number-Real Mutual Generation" refers to the pattern that the real world and the digital world are mutually complemented and promoted, rather than the pattern that the real world is completely digitalized and virtualized that the "Number-Real Mutual Generation Twinning" refers to. Meanwhile, "Number-Real Mutual Generation" also objectively describes the practical process of digital economy in which the real digitalization and digital materialization are mutually promoted and develop in opposite direction. Industrial entities are digitalized to promote innovations of product forms and modes, accelerate industrial transformation and upgrade, cultivate new business modes and facilitate sustainable development. Digital industries, while building a complete cyber world, are also trying to expand from online to offline and enter the real economy. The "Number-Real Mutual Generation" is a method of promoting digital optimization and upgrading, and an important way to make public services more equal, inclusive and convenient to meet people's growing needs for a better life.
