The invention relates to a joint task unloading and resource allocation method in a master-slave MEC network, and belongs to the field of wireless communication and mobile edge computing. The method comprises the following steps: a mobile user in a main cell generates a new calculation task, and sends an unloading request to an MEC server deployed in the cell; the MEC server collects calculation unloading request information of all mobile users in the time slot and delivers the calculation unloading request information to the upper SDN controller; the SDN randomly constructs an initial unloading set for the tasks, performs multi-MEC selection on the tasks in the unloading set, allocates computing resources, updates the unloading set, and solves a minimum objective function value; and if the target function value is not less than the target function value of the last iteration or all tasks are unloaded at the moment, an unloading set, a multi-MEC selection matrix and a computing resource allocation set are out
