Discretion，used to be called “free discretion” is sure to exist in the administrative enforcement. In the practices of administrative enforcement，administrative bodies have discretion in certain enforcement space；administrative counterparts are constantly concerned about how the administrative bodies exercise such discretion and even suspect the justice in the exercise of discretion. In order to enable administrative bodies to enforce laws in a transparent way，and get the administrative counterparts “convinced”，it is indispensable to standardize discretion. Through years of trial，Sichuan has explored to compress the space for discretion of administrative bodies and reduce the “free” margin so as to enhance the legitimacy of law enforcement by formulating the Provisions of Sichuan Province on Standardizing Discretion in Administrative Enforcement. Such standardization of discretion has been applauded and praised by the general public. Undoubtedly，this project is still underway and requires further work and continuous efforts.
