  In holographic duality, dynamics along the emergent extra-dimensional space
describes a renormalization group (RG) flow of the corresponding quantum field
theory (QFT). Following this idea, we develop an emergent holographic
description of a QFT, where not only the information of the RG flow is
introduced into an IR holographic dual effective field theory (HDEFT), but also
the UV information of the QFT is encoded in the HDEFT through the IR boundary
condition. In particular, we argue that this dual holographic construction is
self-consistent within the assumption of bulk locality, showing the following
two aspects: The solution of the Hamilton-Jacobi equation is given by the IR
boundary effective action, and the Ward identity involving the QFT
energy-momentum tensor current is satisfied naturally. We discuss the role of
the RG $\beta$-function in the bulk effective dynamics of the metric tensor
near a conformally invariant fixed point. We claim that this emergent dual
gravity theory generalizes the perturbative Wilsonian RG framework into a
non-perturbative way.
