Abstract:Applying big data to risk governance of major public affairs decision-making is currently facing an issue of system confusion problem. To deal with it, this paper proposes an action framework including construction concept, technical architecture and service design. From the concept to the technical support to the upper level service provision, the action closed-loop of public affairs risk governance driven by big data is formed. The construction concept indicates the construction goals and scope. The technical architecture includes data source, platform support layer, functional layer and service layer. The service design describes the whole process of service logic of risk governance. Furthermore, this paper analyzes the big data action framework for the risk governance of major public affairs decision-making from three perspectives, which will provide an important reference for the new model of risk governance of major public affairs decision-making.
