During the period that the Stateowned Assets Supervision and Administration Commission implements economic value added (EVA) assessment, by taking Shanghai and Shenzhen Ashare listed companies during 20102014 as studying sample, by using STATA software to conduct data processing analysis, this paper empirically tests the relativity between EVA assessment and internal control quality. The study reveals that under the condition that control variables do not have big change, there is positive correlation between internal control quality and EVA.
