Recently, the Yang-Mills gradient flow is found to be a useful concept notonly in lattice simulations but also in continuous field theories. Since itssmearing property is similar to the Wilsoninan "block spin transformation",there might be deeper connection between them. In this work, we define the"effective action" which generates configurations at a finite flow time andderive the exact differential equation to investigate the flow time dependenceof the action. Then Yang-Mills gradient flow can be regarded as the flow of theeffective action. We also propose the flow time dependent gradient, where thedifferential equation becomes similar to the renormalization group equation. Wediscuss a possibility to regard the time evolution of the effective action asthe Wilsonian renormalization group flow.
