We propose a lVIonte Carlo rnethod, xvhich is a hybrid method of the qttantttrm Nlonte Carlotmethod and variational llVIonte Carlo theory, to stttdy the Httbbard nuodel. The theory is basedon the off-diagonal and the Gtrtzxviller type correlation f'actors which are taken into account bya IVIotute Carlo algorithtn. In tlae 4x4 systena otrr method is able to reprodtrce the exact resttltsobt;titted by the diagonalization. An applic?ttion is giveua to investigate tlae half'-filled band caseof two-dimensional sqtrare lattice. The energy is f'avorabl)r cortap;tred xvitl? qtranttrtaa lNzIonte Carlodata.
