The invention relates to a joint task unloading and resource allocation method in a computing resource limited MEC, and belongs to the field of wireless communication and mobile edge computing. According to the method, the problem of limited computing resources is relieved through an idea of restricting unloading, which is mainly reflected in that the unloading decision of a user is influenced by MEC price adjustment. The method comprises the following steps: a user in a cell generates a new calculation task, and sends a task unloading request to an MEC server; the MEC collects calculation unloading request information sent by all users in the time slot, firstly, interaction between the MEC and the users is described through a Stackelberg model, then pricing is carried out on the users according to a differential pricing strategy, calculation resources are distributed to the users through an improved simulated annealing algorithm, and finally service quotation and available calculation resources are returned
