The supervision system is an important component of the socialist system with Chinese characteristics. Since the 18th National Congress of the CPC，China has made overall progress in the reform of the national supervision system，checks on and oversight over the exercise of power，and the construction of the up-and-down supervision network. At the same time，there are still some problems，such as the power structure is not reasonable，the public power is too strong，and the supervision power is weak and nominal. So we should further scientific allocation of power，and form scientific power structure and operation mechanism；to carry out the whole process of budget supervision and performance management；to push forward a coordinated system under which officials don’t dare to，are unable to and have no desire to commit acts of corruption，and gradually establish an authoritative，efficient oversight system with complete coverage under the Party’s unified command.
