We propose a new mechanism toward the solution to the doublet-triplet Higgs mass splitting problem in the supersymmetric grand unified theory. Our model is based on the gauge group SU(5)H\ifmmode×\else\texttimes\fiSU(5)GUT, where SU(5)H and SU(5)GUT are a new strong gauge interaction and the ordinary grand unified gauge group, respectively. The doublet-triplet Higgs mass splitting is realized through the quantum deformation of moduli space caused by the strong SU(5)H gauge dynamics. The low energy description of our model is given by the minimal supersymmetric standard model.
