The relationship between teachers and students in higher vocational colleges is the most basic interpersonal relationship in campus life. At present, there are serious maladjustment phenomena in the communication relationship between teachers and students of higher vocational colleges, which are manifested as: lack of communication time and space, weak communication spirit, unbalance of communication construction, etc. The reasons lie in the coupling effect of tendency to pursue practicality, the influence of authoritative culture, the improper use of information technology, and the alienation of receiving training. To reconstruct the relationship between teachers and students of higher vocational colleges in the new era, it is necessary to extend and develop the physical space, shape and deepen the spiritual space, and improve and optimize the network space.
