By using the transverse-field Ising model, the possible contribution of the quantum effect to the ferroelectric behaviors for BaTiO3 was described. It is found that the quantum effect can reduce the ferroelectric polarization obviously. The theoretical results based on the new model are in good agreement with the experimental ones.
