  In this paper we study the holographic dark energy model proposed by Li from
the statefinder viewpoint. We plot the evolutionary trajectories of the model
with $c=1$ in the statefinder parameter-planes. The statefinder diagrams
characterize the properties of the holographic dark energy and show the
discrimination between this scenario and other dark energy models. We also
perform a statefinder diagnostic to the holographic dark energy model in cases
of different $c$ which given by three fits to observational data. The result
indicates that from the statefinder viewpoint $c$ plays a significant role in
this model and should thus be determined seriously by future high precision
experiments.
