We present a supersymmetric composite model with dynamical supersymmetry breaking. The model is based on the gauge group SU(2){sub S}{times}SU(2){sub H}{times}SU(3){sub c}{times}SU(2){sub L}{times}U(1){sub Y}. Supersymmetry is dynamically broken by the nonperturbative effect of the SU(2){sub S} {open_quotes}supercolor{close_quotes} interaction. The large top quark Yukawa coupling is naturally generated by the SU(2){sub H} {open_quotes}hypercolor{close_quotes} interaction as recently proposed by Nelson and Strassler. The supersymmetry breaking is mediated to the standard model sector by a new mechanism. The electroweak symmetry breaking is caused by the radiative correction due to the large top quark Yukawa coupling with supersymmetry breaking. This is the {open_quotes}radiative breaking scenario,{close_quotes} which originates from the dynamics of the supercolor and hypercolor gauge interactions. {copyright} {ital 1997} {ital The American Physical Society}
