Purpose/Significance Based on the value co-creation theory, the paper analyzes the feasibility of user participation in library space reconstruction, and proposes a framework model of value co-creation for space service innovation in hospital library. Method/Process Combining theoretical analysis with practice, taking the library of Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology as an example, the paper determines the points of library space reconstruction and identifies the focal users of the library through the user demand survey and user spatial behavior analysis, then realizes user participation in the process of space reconstruction through the group interview. Result/Conclusion User participation is the basis of realizing the value co-creation of library space reconstruction. Library realizes user participation by identifying user needs, enhancing user perceived value and innovating user participation forms.
