The measure center and minimal contracting center for amenable group actions are investigated. More precisely
the definitions of the measure center and the minimal contracting center for amenable group actions are given firstly. Then the main result that the measure center of a nonempty set equals to its minimal contracting center is proven. It generalizes the conclusion of Zhou to amenable group actions.
