2. AI Application Concept
   : The company’s technical layout in the AI field has become a market focus [3];
3. Capital Inflows

• Cross-domain Collaboration
  : The integration of national defense and military industry with AI technology (such as intelligent air traffic control systems) brings differentiated competitive advantages to the company;
• Index Component Effect
  : Passive capital inflows into the CSI A500 Index (e.g., A500 ETF turnover exceeded 3.5 billion yuan [1]) continue to support the stock price;
