[目的/意义]数智驱动背景下，信息资源管理的社会职能由信息资源提供者向知识服务创新者、社会问题解决者和文化生态构建者转变，用户信息获取范式由“搜索—筛选”向“提问—生成”转变。以DeepSeek为代表的生成式人工智能作为一种新的信息获取渠道，逐渐被用户视为类似于信息资源管理的信息服务模式。[方法/过程]聚焦生成式人工智能信息资源管理职能的形成与发挥这一现象，从技术、社会、认知的多重维度探寻其成因，分析技术优势下生成式人工智能作为信息渠道的社会效益，明晰由此产生的技术中介认知及其异化挑战。[结果/结论]探索了人机协同的认知生态系统构建策略，为解决生成式人工智能发挥信息资源管理职能带来的挑战、发展数智驱动的信息服务提供了参考。

[Purpose/significance] In the context of digital information, the social function of information resource man⁃agement has changed from information resource provider to knowledge service innovator, social problem solver and cul⁃tural ecology builder, and the user information acquisition paradigm has changed from "search - screening" to "ques⁃tion - generation". Generative artificial intelligence represented by DeepSeek, as a new channel for information acqui⁃sition, is gradually regarded by users as an information service model similar to information resource management.[Method/process] Focusing on the phenomenon of the formation and exertion of the information resource management function of generative artificial intelligence, exploring its causes from multiple dimensions such as technology, society and cognition, analyzing the social benefits of generative artificial intelligence as an information channel under techno⁃logical advantages, and clarifying the resulting technology intermediary cognition and its alienation challenges. [Result/
conclusion] Explored the construction strategies of the human-machine collaborative cognitive ecosystem, provided references for solving the challenges brought by generative artificial intelligence in performing the function of informa⁃tion resource management and developing digital intelligence-driven information services.
