Abstract: We present two-loop renormalization of $\phi^3$ model effective action by using the background field method and cutoff momentum regularization. In this paper we also study a derivation of the quantum equation of motion and its application to the renormalization procedure.

Key words and phrases: quantum equation of motion, cubic model, renormalization, cutoff momentum, background field, regularization, effective action, coupling constant.
