Abstract： [Purpose/significance] An influential factor interpretation structure model focused on the elderly information need is proposed in this paper. It is used to analyze the causal relationship among different factors and their influences exerted on the elderly information needs. [Method/process] Based on the relevant research achievements, this paper identifies 20 influence factors of the elderly information needs through the first round of expert investigation. Then this paper identifies the relationship of the influence factors and establishes adjacency matrix through the second round of expert investigation. Based on these, the adjacency matrix is calculated to get the reachability matrix. By decomposing the reachability matrix, we divide the influence factors into five levels and establishes the interpretive structural model about the elderly information needs, which can be employed to analyze the hierarchical relationship of influence factors and their influence on the elderly information need.[Result/conclusion] The influential factors of elderly information needs can be divided into surface-level, middle-level and deep-level factors. To be more specific, the surface-level factors refer to the most direct factors of elderly information needs; the lesser one is identified as middle-level factor; the core factor of elderly information needs is regard as deep-level factor.
