  In this work, we study the relativistic quantum kinetic equations in 2+1
dimensions from Wigner function formalism by carrying out a systematic
semi-classical expansion up to $\hbar$ order. The derived equations allow us to
explore interesting transport phenomena in 2+1 dimensions. Within this
framework, the parity-odd transport current induced by the external
electromagnetic field is self-consistently derived. We also examine the
dynamical mass generation by implementing four-fermion interaction with
mean-field approximation. In this case, a new kind of transport current is
found to be induced by the gradient of the mean-field condensate. Finally, we
also utilize this framework to study the dynamical mass generation in an
external magnetic field for the 2+1 dimensional system under equilibrium.
