The dynamic theory for disordered superconductivity is suggested based on the fracton-electron interaction. It has been demonstrated that electrons in disordered superconductors can feel an attractive interaction by exchange of virtual fractons. A normal state is unstable with respect to such an interaction, and a superconducting state is formed through the association of electrons in pairs with opposite wave vectors and spins. The critical temperature for percolation superconducting model can be derived from this theory.
