We investigate what can be learned at a linear collider about the sector of electroweak symmetry breaking from a precise measurement of the Higgs boson production cross section through the process e+e^\ensuremath-\ensuremath→hZ. We focus on deviations from the standard model arising in its minimal supersymmetric extension. The analysis is performed within two realistic future scenarios, taking into account all prospective experimental errors on supersymmetric particle masses as well as uncertainties from unknown higher order corrections. We find that information on tan\ensuremathβ and MA could be obtained from a cross section measurement with a precision of 0.5\ensuremath-1%. Alternatively, information could be obtained on the gaugino mass parameters M2 and \ensuremathμ if they are relatively small, M2,\ensuremathμ\ensuremath≈200GeV.
