Recent progress in understanding modulus stabilization in string theoryrelies on the existence of a non-renormalization theorem for the 4Dcompactifications of Type IIB supergravity which preserve N=1 supersymmetry. Weprovide a simple proof of this non-renormalization theorem for a broad class ofType IIB vacua using the known symmetries of these compactifications, therebyputting them on a similar footing as the better-known non-renormalizationtheorems of heterotic vacua without fluxes. The explicit dependence of thetree-level flux superpotential on the dilaton field makes the proof more subtlethan in the absence of fluxes.Comment: 16 pages, no figures. Final version, to appear in JHEP. Arguments for validity of R-symmetry made more explicit. Minor extra comments and references adde
