  As a first step to generalize the structure of loop quantum cosmology to the
theories with the spacetime dimension other than four, the isotropic model of
loop quantum cosmology in 2+1 dimension is studied in this paper. We find that
the classical big bang singularity is again replaced by a quantum bounce in the
model. The similarities and differences between the 2+1 dimensional model and
the 3+1 dimensional one are also discussed.
