We calculate the higher-loop corrections to the cross section of the Higgsstrahlung process $e^+e^- \\rightarrow Z h$, along with the tri-Higgs coupling and the wave-function renormalization. We find noticeable contribution to the total Higgsstrahlung cross section, especially coming from two-loop diagrams. We also find that the correction to the tri-Higgs coupling is complex when this extra scalar is lighter than half of the center of mass energy.
