An extensive quantum Monte Carlo calculation is performed to probe a possible electronic origin of the high-temperature superconductivity in cuprates by studying Emery`s three-band Hubbard model. The d{sub x{sup 2}-y{sup 2}} pairing correlation is found to grow with the system size when the d electron repulsion U{sub d} or the d-p level off-set {Delta}{epsilon} exceed the one-electron band width, where the correlation also starts to increase with U{sub d} or {Delta}{epsilon}. The authors have detected this in both the charge-transfer and Mott-Hubbard regimes for appropriate doping concentrations.
