In this paper, forward-backward asymmetry and differential cross section oftop quark in flavor violating $Z'$ model up to $\mathscr{O}(\alpha_s^2\alpha_X)$ at Tevatron are calculated. In order to account for the top observedlarge forward-backward asymmetry, the new coupling $g_X$ among $Z'$ and quarkswill be not much less than strong coupling constant $g_s$. After including thenew higher order correction, the differential cross section can fit the databetter than those only including the leading contributions from $Z'$, while theforward-backward asymmetry is still in agreement with the measurement.
