  In this paper, we consider the Cauchy problem for the one-dimensional
compressible isentropic magnetohydrodynamic (MHD) equations with no vacuum at
infinity, but the initial vacuum can be permitted inside the region. By
deriving a priori $\nu $ (resistivity coefficient)-independent estimates, we
establish the non-resistive limit of the global strong solutions with large
initial data. Moreover, as a by-product, the global well-posedness of strong
solutions for both the compressible resistive MHD equations and non-resistive
MHD equations are also established, respectively.
