The transition matrix of the downward continuation of boundary conditions about elastic wave equation inversion was established.The solving method and stable conditions of the downward continuation of boundary conditions were obtained.The problem that the boundary conditions at downward continuation depth points cannot be determined has been solved so as to improve the speed and precision of inversion calculation.
