[目的/意义]厘清数据价值实现的核心影响因素与作用路径，以促进数据价值的有效释放与实现。[方法/过程]构建数据价值实现的多链系统，采用CFCS-DEMATEL 方法识别因素间的因果关系，并结合模糊认知图开展单链、双链与三链仿真，识别链内与跨链的核心因素并解析关键影响路径。[结果/结论]单链动能不足；双链能够提升数据流动效率；三链协同可显著增强价值实现效能。不同链条的核心影响因素存在差异，链内与跨链的影响路径随数据流动阶段变化而呈现差异化。可通过提升单链的价值实现能力、增强跨链的传导效能和推进三链的协同治理来促进数据价值实现。

[Purpose/significance] This study aims to clarify the core impact factors and pathways in data value realiza⁃tion, thereby promoting the effective release and realization of data value. [Method/process] A multi-chain system for data value realization is constructed. The CFCS-DEMATEL method is employed to identify causal relationships among factors, and fuzzy cognitive maps are used to simulate single-chain, double-chain, and triple-chain models to identify core factors within and across chains and analyze key impact paths. [Result/conclusion] A single-chain provides limit⁃ed momentum; a double-chain improves data flow efficiency; and triple-chain collaboration significantly enhances val⁃ue realization performance. The core impact factors differ across the single-, double-, and triple-chain models, and the impact paths within and across chains vary with the stage of data flow. Data value realization can be improved by strengthening single-chain capabilities, enhancing cross-chain collaboration, and advancing triple-chain collabora⁃tive governance.
