Abstract: Social stability risk assessment， as a necessary procedure of administrative regulations and government decisions， can help to enhance the legality and rationality of government decision-making， and keep social stability risk down caused by administration. As the system for normalizing the reasoning of government decision-making， it is a self-innovation in the system under the concept of administrative self-restraint， which reveals the self-examination and self-restraint of administrative power through communicating with legal and political systems. The validity of social stability risk assessment lies in the active restraint of government power which may be abused in the process of decision-making， the attention paid to the predictability and acceptance of the results of government decisions. However， it should be warned that the current social stability risk assessment is departing from the technological understanding to the ideology.

Key words: social stability risk assessment, administrative self-restraint, administrative decision-making
