Abstract: This paper uses the grounded theory and the interpretative structural model（ ISM） method to determine the influencing factors of the integration service effect of the store， and then reveals the relationship between the influencing factors of the integration service effect of the store. The research shows that most of the library-store integration projects in China are policydriven， and policy support is the most fundamental reason affecting the service effect of the library-store integration， which plays the most critical role in the service effect of the library-store integration. In addition， geographical location， cooperation mode and store environment， as the middle level， also play an important role in the service effect of the library-store integration. Based on this， this paper believes that we should start with the formulation of diversified policies， the optimization of cooperation models， and the follow-up of user requirements to improve the effect of the integration service of the library-store integration.
