This letter proposes a multi-agent deep reinforcement learning (MADRL) framework for resource allocation in air-ground integrated multi-access edge computing (MEC) networks, where unmanned aerial vehicles (UAVs) provide computing services in addition to ground-computing access points (GCAPs). For maximizing the computation efficiency, the resource allocation problem is formulated as the mixed-integer programming problems. Then, we develop a cooperative deep deterministic policy gradient (CODDPG) algorithm to solve the problem via an observable Markov game. The simulation results demonstrate that the proposed algorithm outperforms centralized reinforcement learning in terms of the computation efficiency.
