Artificial intelligence, as the core driver of the new round of technological revolution and industrial transformation, has been elevated to the level of a national strategic priority. The Development Plan for the Next Generation of Artificial Intelligence clearly states that China will achieve the ambitious goal of leading the world in artificial intelligence technology by 2030. This strategic deployment not only injects strong impetus into the country's overall development, but also provides an important opportunity for the digital transformation of ethnic regions. In the context of building a “Digital China”, ethnic regions are actively integrating into this wave and promoting the all-round development of the economy and society through technological innovation. Take the Smart Education platform in the Guangdong-Hong Kong-Macao Greater Bay Area as an example. The platform makes full use of artificial intelligence technology to achieve efficient allocation and precise delivery of educational resources, significantly improving educational equity and teaching quality. This typical case vividly demonstrates the deep integration of technology and the building of the national community, and shows the great potential of artificial intelligence in promoting coordinated regional development. However, it is worth noting that there is still a significant gap in digital infrastructure construction between the East and the West. Problems such as limited 5G network coverage and uneven distribution of computing power resources have led to significant differences in regional development levels. This imbalance not only restricts the pace of digital transformation in ethnic minority areas, but also poses a serious challenge to the sharing of technological dividends. Therefore, how to narrow the digital divide between the east and the west through policy guidance and technological support has become an important issue that needs to be addressed urgently at present.
