The full one-loop corrections, both the weak and QED corrections, to the process $e^+ e^- \to Z \phi $ ($\phi=h^0,H^0$) at the Higgs factories are presented. Up to the $O(\alpha_{EM})$ level, the virtual corrections are evaluated in a Feynman-diagrammatic approach. The real emission corrections are computed using Feynman Diagram Calculation (FDC) system and the collinear divergences are regularized by the structure functions of electron. Using the FDC system, we study the corrections both in the SM and the two Higgs doublet model (2HDM), respectively. After taking into account experimental constraints from the current LHC data, we propose four interesting benchmark scenarios of 2HDM for future colliders. By using these benchmark scenarios, we evaluate the deviation of $ \Delta\sigma(e^+ e^- \to Z \phi)$ from their Standard Model (SM) values. We also examine $\phi\to b\bar{b}$ and $\phi\to \tau^+\tau^-$, which may receive large EW contribution from triple Higgs couplings which are absent in the SM. It is found that for these benchmark scenarios, both EW and real emission corrections are sizable and could be measured at a future $e^+ e^-$ collider} such as the ILC, CLIC and CEPC.
