Traditional jurisprudence has produced few studies at the level of institutional operation,resulting in a lack of knowledge about the structures,actors and symbols involved in the modernization of social governance,to the extent that the modernization of the social governance system is in practice misunderstood as rule of law,informatization and adoption of technology.The core issue of social governance is the division of oversight and penalty costs between the state and individuals,but we need to draw upon a legal platform to facilitate cooperation between public and private rights.The modernization of social governance is a matter of using legislation to provide techniques and a statutory platform for cooperation in an open society,ensuring the reasonable division of social governance information and penalty costs when public and private rights overlap.The social governance techniques that enable public and private rights to work together involve taking a group of observable symbols or organizations on which consensus has been reached as a statutory platform,with all sides making this platform bear more responsibility in order to maximize their own interests and minimize their transaction costs,with no need to inquire further into its particular constitution.
