：文章介绍了大数据时代的特点及其对国家情报工作的具体要求，分析了国家情报工作在大数据时代的不和谐现象及问题所在，并以此为基础从内力激发机制、外力触发机制以及内外力协同机制三方面研究了国家情报工作系统演替的动力机制，进而提出促进其演替的动力驱动方式，即加强支撑力、拉力和推力的积极作用，减弱压力的消极作用。

This article briefly introduces the characteristics of the age of big data and its specific requirements for national intelligence activities and analyzes the existing unharmonious phenomena and problems of national intelligence activities in the age of big data. On this basis, the dynamic mechanisms of the succession of the national intelligence activities system is studied from three aspects: the internal force excitation mechanism, external force triggering mechanism and internal and external force coordination mechanism，and proposes the driving mode that is strengthening support force, pulling force, thrust and weakening pressure to promote its harmonious succession of national intelligence activities in the age of big data.
