In this paper, we consider the optimal dividend strategy in the perturbed compound Poisson risk model with ivestment interest. Our aim is to find an optimal dividend strategy that maximizes the cumulative expected discounted dividend payments. We characterize the optimal value function as the viscosity solution of the associated Hamilton-Jacobi-Bellman (HJB) equation and prove that there exists an optimal barrier strategy which is optimal among all admissible dividend strategies in some special cases.
