Policy Impact on AI Industry - The State Council recently issued an opinion on the implementation of the "Artificial Intelligence +" initiative, outlining six key actions for accelerating AI development, including technology, industry growth, consumer quality enhancement, and global cooperation. The document sets development goals for 2027, 2030, and 2035, providing a top-level design for promoting AI at the national level. Analysts believe this policy will act as a catalyst for the AI industry chain, similar to the "Internet +" policy in 2015, leading to increased demand and penetration across the industry [8]. AI as a Growth Driver - According to Dongguan Securities, artificial intelligence is a core driver of growth in the technology sector and a key battleground for global tech competition. The continuous cost reduction and efficiency improvement of domestic large models, such as DeepSeek, will accelerate the implementation of AI applications. Strong national policy support is expected to promote the rapid adoption of new intelligent terminals, including AI smartphones, PCs, smart connected vehicles, and robots, benefiting upstream computing power and downstream application companies [9].
