An extended expression of the dynamic self-energy of one-particle Green function is obtained up to order 1/m in m-component Bose systems, by means of a complex unperturbed propagator. As applications of it, dynamic critical exponents of the TDGL model as well - as of a Bose system are evaluated to order 1/m, for both short-range and long-range inter actions. These confirm the previous results of the TDGL model and of the Bose system for short-range interactions. An effective interaction V.rr(p, i(J).) is obtained to order 1/m, which is useful for discussion on anomalies of transport coefficients near the A.-transition.
