Abstract: [Purpose/Significance] Postgraduates are the new force and reserve force of academic research. The discussion about trust and influencing mechanism of their academic information consumption will help improve the quality of academic information production and service, and better meet their academic information consumption needs. The contribution of this paper is on the one hand, few articles systematically studied postgraduate students' academic information consumption behavior from the perspective of trust; on the other hand, the research conclusion is a new idea: the study on the analysis of the graduate students' trust in academic information based on consumer behavior impact mechanism, from creating the atmosphere of academic information sources of trust, strengthening academic information channels fiduciary level, improving the level of academic information content trusted three angles proposed strengthening graduate student academic information consumption behavior trust mechanism,. [Method/Process] Based on the relevant theories of trust and information utilization behavior, interviews of 40 students were used to obtain the first-hand data. Before the formal interview, two authors conducted the pre-interview with 10 postgraduate students with rich experience in academic information consumption, respectively. Then, according to the feedback of the pre-interview, they determined the formal interview outline. Using the method of grounded theory to code the data in open coding, spindle coding and selective coding, a model of the influencing mechanism of postgraduate students' trust in academic information consumption was constructed, and the model was explained in detail. Finally, the strategies for improving postgraduate students' academic information consumption were proposed. [Results/Conclusions] Information source, information channel characteristics, the information content characteristic and personal characteristics influence postgraduates' perception of academic information trust, and postgraduates' perception of academic information trust affects their information consumption. Perceived trust plays a mediating role between the above four factors and academic information consumption. This paper proposes strategies to improve the academic information consumption of postgraduate students from the following three aspects: firstly, two-way efforts to create an atmosphere of trust in academic information sources. Secondly, to improve services and enhance the credibility of academic information channels. Thirdly. To attach importance to quality and improve the credibility of academic information content.
