Abstract
We study a coupling flow of pure QCD gauge system by using the Monte C arlo Renormalization Group method. A rough location of the renormalize d trajectory in two coupling space is obtained. Also we compare 4 diff erent actions; (a)standard Wilson, (b)Symanzik's, (c)Iwasaki's and (d) QCDTARO's. The rotational symmetry is restored better as an action get s close to the renormalized trajectory.
