By using a convenient perturbative expansion method, a scalar field φ in scalar QED with Chern-Simons term is quantized. Under the approximation oi one-loop diagram, we have derived the effective action for vector field Aμ and obtained two branches of (unstable) elementary excitation spectra. The coupling coefficient of Chern-Simons term is not affected by the quantization of φ field.
