Abstract
We make a detailed investigation on the quantum corrections to
Chern-Simons spinor electrodynamics.
Starting from Chern-Simons spinor quantum electrodynamics
with the Maxwell term 
and by calculating the vacuum polarization tensor, electron self-energy
and on-shell vertex, we explicitly show that the Ward identity is
satisfied and hence verify that
the physical quantities are independent of the procedure of
taking 
at tree and one-loop levels.
In particular, we find the three-dimensional
analogue of the Schwinger anomalous magnetic moment term of the electron
produced from the quantum corrections.
