In this paper, we investigate the strong convergence of the semi-implicit Euler-Maruyama (EM) method for stochastic differential equations driven by a class of Lévy processes. Comparing to existing results, we obtain the convergence order of the numerical scheme and discover its relation with the parameters of the class of Lévy processes. In addition, the existence and uniqueness of numerical invariant measure of the semi-implicit EM method is studied and its convergence to the underlying invariant measure is also proved. Numerical examples are provided to confirm our theoretical results.
