  First we give a review of the spurion formalism and the exact renormalization
group equations for soft supersymmetry breaking parameters in general gauge
theories. Next we discuss the minimal supersymmetric standard model coupled to
superconformal theories leading to hierarchical Yukawa couplings by large
anomalous dimensions of quarks and leptons. The soft scalar masses are found to
satisfy the noble sum rule in IR regime. It is possible construct the models
such that the degenerate squark/slepton masses are realized thanks to this IR
sum rule. However, it is found also that this degeneracy is slightly broken
mainly by the radiative corrections of the SM gaugino mass insertion. We show
that the degeneracy is sufficient for the squark sector, but weak for the
slepton sector to avoid the supersymmetric flavor problems.
