  We propose a Lagrangian function, which combines Landau-Ginzburg term and
Chern-Simons term, for describing the competition between disorder and
superconductivity. To describe the normal-to-superconducting transition in the
thin superconducting films, we apply Wilson's renormalization group methods
into this Lagrangian function. Finally, we obtain a scaling law between
critical temperature (T_c), film thickness (d), sheet resistance of the film at
the normal state (R_s), and number density of the electrons at the normal state
(N). Such a scaling law is in agreement with recent experimental investigations
[Ivry, Y. et al, Physical Review B 90, 214515 (2014)]. Our finding may have
potential benefits for improving transition temperature T_c.
