In recent years, when scholars generally use public space as a path to interpret bookstore space, the particularity of its spatial attributes has been obscured. In fact, bookstores are no longer just a terminal for selling books, nor a pure public space, but have evolved into a threshold space that combines spiritual consumption with material consumption, individual consumption and collective consumption. It is both the expression of group will and individual consumption behavior. The place is also a non-public, non-private, critical enclave; it not only has the productivity of the inner space, but also promotes the surrounding business forms through positive externalities in the form of comfort objects. This paper attempts to re-examine the spatial attributes and consumption significance of bookstores from the perspective of consumer science, and then explores the future path of urban bookstores from two levels of theory and practice.
