[Purpose/significance] The introduction of big data analysis into intelligence studies has become the trend of the developed age.It is of great significance to promote and establish the intelligence studies theoretical system driven by big data to identify the "natural moat"and "thoroughfare"between them.[Method/process] From the perspective of five key links of intelligence studies—intelligence requirement and intelligence problem definition,intelligence hypothesis,intelligence gathering and processing,intelligence analysis and production,the intelligence products delivery and feedback,this paper combs the intersections and gaps of big data analysis and intelligence studies in the method of comparative study,to point out its value and disadvantages.[Results/conclusion] The impact of big data analysis on intelligence studies is deepening,but there are still many "natural moats",which are rooted in the fact that big data analysis cannot replace intelligence personnel’s smart and subjective.However,in terms of evolution,big data analysis and intelligence studies will continue to develop and then integrate with each other.
