We have studied the variability of \object{S5 0716+714} at radio 15 GHz and $\gamma$-ray band using three different methods. A possible periodicity of $P_{15 GHz}=266.0\pm11.5$ and $P_{\gamma}=344.0\pm16.4$ days are obtained for radio 15 GHz and $\gamma$-ray light curves, respectively. The variability may be related to the intrinsically emission mechanism. The difference between the variability timescales of radio 15 GHz and $\gamma$-ray may be due to that the emission of radio 15 GHz is produced via the synchrotron process, while the $\gamma$-ray is produced by both the SSC and EC processes.
