Two mass generation mechanisms for gauge theories are studied. It is proved that in the abelian case the topological mass generation mechanism introduced in hep-th/9301060, hep-th/9512216 is equivalent to the mass generation mechanism defined in hep-th/0510240, hep-th/0605050 with the help of ``localization'' of a nonlocal gauge invariant action. In the nonabelian case the former mechanism is known to generate a unitary renormalizable quantum field theory describing a massive vector field.
