AB  - This paper, based on the WIPO patent database, comparatively analyzes the technological development and innovation performance of six Northeast Asian countries in the field of artificial intelligence. The research defines five stages of artificial intelligence technology development, and constructs the theory of technological evolution cycles. Using patent quantity, quality index, technology introduction and diffusion and other multi-dimensional indicators, it fully reflects the technological strength and interactive relationships of different countries' artificial intelligence. The research finds that Japan and South Korea are in a leading position in artificial intelligence technology, followed by China and Russia, while North Korea and Mongolia lag behind. However, there exists complementarity between the technologies of various countries, so regional cooperation should be strengthened. This research enriches the theory of technological evolution, and provides a basis for Northeast Asian countries to formulate differentiated artificial intelligence technology development strategies.
