A second order time–space implicit/explicit iterative scheme for the stationary Navier–Stokes equations is designed, where the spatial discretization is based on the mixed finite element method and the time discretization is based on the second order implicit/explicit (the Crank–Nicolson/Admas–Bashforth) scheme. Under a weak uniqueness condition, the optimal H 1-L 2 error estimates related to the mesh size h and time step size τ of the iterative solution (u h n, p h n) to the exact solution (u ̃, p ̃) and the optimal L 2 error estimate related to h and τ of the iterative solution u h n to the exact solution u ̃ are provided. In numerical aspect, some comparisons with the first order time–space iterative method are made to confirm the efficiency of the proposed second order scheme.
