随着生成式人工智能与大数据资源的融合应用，可供主体的数智化特性逐渐凸显，在强化AI生成能力的同时拓宽了用户认知边界，为可供思想提供了新的延续支点。文章首先以生成式人工智能背景下的数智可供性理论建构为切入点，从“赋能”属性和“关系”机制梳理可供条件下数智与认知的逻辑关联；其次，借鉴可供思想的数智化发展机理，结合四种理论模式解构认知带宽的可供特性；最后，围绕生成式环境下认知带宽在“资源-能力-空间”的三重升维机制，探讨数智供给量级优势、技术可供内生潜力、场域自主化发展的实践过程，以期深入理解“数智何以赋能认知”的关键命题。

With the integration and application of generative artificial intelligence and big data resources, the characteristics of the digital intelligence of the available subjects are gradually highlighted, which broadens the boundary of the user's cognition while reinforcing the generative ability of AI, and provides a new pivot point for the continuation of available ideas. Firstly, this paper takes the theoretical construction of digital intelligence availability in the context of generative AI as an entry point, and analyses the logical connection between digital intelligence and cognition under the condition of availability from the attribute of "empowerment" and the mechanism of "relationship". Secondly, we draw on the developmental mechanism of digital intelligence in the context of availability of ideas, and deconstruct the availability of cognitive bandwidth by combining the four theoretical models. Finally, we explore the practical process of quantitative advantage of digital intelligence supply, endogenous potential of technology availability, and autonomous development of field around the triple upgrading mechanism of "resource-capability-space" of cognitive bandwidth in generative environment, in order to understand in depth "We will explore the quantitative advantage of digital intelligence supply, the endogenous potential of technology availability, and the practical process of autonomous development of the field, in order to deeply understand the key proposition of "How Digital Intelligence Enables Cognition".
