Abstract.In this paper it is shown that the Hardy inequality for discrete form can be improved by means of a sharpening of Hölder's inequality. A similar result for the Hardy integral inequality is also proved. And the coefficient $\left(\frac{p}{p-1}\right)^p$ of the classical Hardy inequality is further discussed.
