Abstract: Absence of administration accountability is one of the deep-rooted institutional factors that cause the abuse of public power.The direction of reform should be “to improve the administrative accountability system for the promotion of constraints on administrative discretion”,which focuses on the expansion of accountability in a broad sense,and the accountability targets shall include the responsible public servants in executive body.This kind of broad accountability directly reflects the responsibilities and obligations of the executive body—the grass-roots civil servants in government.In order to regulate the exercises of power effectively,we must adjust the dialectical relationship between administrative accountability and administrative discretion,and further strengthen the building of the administrative accountability system.

Key words: administrative discretion, administrative accountability, institutional constraints
