Abstract: Optimal dividend payments and capital injections of the piecewise-deterministic compound Poisson risk model were discussed.The objective of an insurance business under consideration was to maximize the discounted dividend payments minus the penalized discounted capital injections.By a method to determine numerically the solution to the HJB equation,the corresponding Hamilton-Jacobi-Bellman equation was derived.And the optimal dividend and strategy was the Threshold strategy.This conclusion made the risk model have more realistic and more practical significance. -
