当基础模型成为AI应用的底座，学者称平台竞争转向生态较量

Core Insights - The richness of application ecosystems is becoming a key way for large model vendors to showcase their capabilities, with domestic foundational models rapidly penetrating various scenarios [1] - The head effect of foundational models is becoming more pronounced as the "hundred model battle" shrinks, with DeepSeek, Tongyi, and Tencent's Hongyuan ranking among the top ten globally according to the Chatbot Arena [1] - Foundational models are evolving into a new digital infrastructure that can spawn numerous applications, shifting the competitive landscape from individual companies to ecosystem battles [1][2] Industry Analysis - The ability of a large model platform to attract more developers and build a vibrant application ecosystem may lead to a "winner-takes-all" scenario, raising new challenges for antitrust authorities regarding market definitions [2] - Regulatory frameworks should be cautiously defined to balance intervention and market incentives, allowing private enterprises maximum innovation space in digital infrastructure, as long as national information security and fairness for individuals and small businesses are not compromised [2] - Although the ecosystem of foundational models is expanding rapidly, the impact of AI on macro productivity may take time to manifest, reflecting the classic Solow paradox where technological advancements do not immediately translate into productivity gains [3] - AI agents are emerging as a popular application direction for large models, with predictions that 20%-30% of office tasks could be automated, potentially reallocating labor to new technology-driven fields [3]
