We study the dilaton stabilization in models with anomalous U(1) symmetry by
adding specific string-motivated, non-perturbative corrections to the
tree-level dilaton K\"{a}hler potential. We find that the non-perturbative
effects can stabilize the dilaton at a desirably large value. We also observe
that the size of Fayet-Iliopoulos term is reduced at the stabilized point.
