Which part of the black hole defines the boundary governing the mechanism of Hawking radiation emission?

Answer

The event horizon

Hawking radiation is a phenomenon whose behavior is determined by the quantum field effects happening near the boundary of no return, known as the event horizon, rather than processes occurring at the infinitely dense singularity.
