回应数字经济浪潮对于设计的全新要求，2022北京国际设计周以“数实互生”为主题，从设计的角度出发，探讨数字世界与实体世界的应有关系，构建支持数字经济良性发展的设计方法论。“互生”是植物学概念，是叶序的一种，指叶片相间生长于茎的两侧，总体对称却非一一对应，并且交互着向上生长。“数实互生”指向实体世界与数字世界互为补充、互相促进的模式，而非“数实孪生”所指向的将实体世界完全镜像地数字化、虚拟化。同时“数实互生”也客观描述了实体数字化、数字实体化，相生交互、相向而行的数字经济实践进程。实体产业通过数字化，推动产品形态和生产方式的创新，加速产业转型升级，催生新的商业模式，促进可持续发展。数字产业在构建完整网络世界的同时，也在尝试从线上走到线下，进入实体经济领域。“数实互生”是推动数字化优化升级的方式，是提升公共服务均等化、普惠化、便捷化水平，满足人民日益增长的美好生活需要的重要途径。

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.
