It allows the renormalized Higgs mass to be finite and also improves the unification of the coupling constants at the Grand Unification scale.  Since R-parity must be conserved, then all of its particles must be produced in pairs, and its lightest particle cannot decay.  It is the basis for such postulated particles as selectrons, neutralinos, photinos, and gluinos.  Relating gravitational forces to subatomic forces, FTP, name this hypothetical equivalence between fermions and bosons, often abbreviated SUSY.
It allows the renormalized Higgs mass to be finite and also improves the unification of the coupling constants at the Grand Unification scale.
