Abstract：As the world is changing fast and as the economic and social issues are getting more complicated,the traditional governance models of every country can no longer deal effectively with the challenges,complexities,and risks of the new era .The new generation of information technology,such as big data,cloud computing and internet of things have created necessary conditions for the transformation of governance models .Big data,the natural product of information technology,has introduced new ways to cognize data and opened up more space of imagination in utilizing data . Smart public decision making refers to a big-data-driven public decision-making model which assists decision makers in making more scientific and effective decisions in order to realize public benefit in complicated economic and social conditions .The model is supported by the new generation of information technology which utilizes big data resources featuring full range,quick speed,high value and diversity for real-time perception,analysis and prediction of the trend of development,and streamlining the decision-making process .Essentially,smart public decision making is a new big-data-driven public decision-making model of maximizing public interest .Supported by the new generation of information technology,it has the characteristics of comprehensiveness,objectivity and transparency,real-time and continuity,and autonomy and decentralized governance . Based on an analysis of the four basic elements of decision making,namely the body,process,means and goal,the internal logical relationship between big data and smart public decision making becomes clear .From the perspective of the body,big data facilitates the simultaneous experience and the logic of action of collaborative governance .As for the process,big data shows an entire chain of real-time consecutive decisions,on the basis of which predictions are made .As for the measures,big data can solve the technical problems that usually occur in data-driven decision making .In terms of the objective,big data can effectively guide and motivate public benefits . Smart public decision making has many new features such as comprehensiveness,objectivity and transparency,real-time and continuity,and autonomy and decentralized governance .Comprehensiveness means that with big data,public organizations are able to perceive a comprehensive range of social issues and public needs,discover the hot spots of demand,classify customer needs and provide accurate and customized service .Objectivity and transparency means that with this scientific model and consistent criteria,public organizations can involve the public in the objective and fair process,the scientific and effective system,and the open and transparent outcomes .Real-time and continuity means that the whole process from data collection,information transmission,knowledge mining,to decision-making and feedback is accomplished real-time and continuously .Autonomy means that smart public decision making exploits the features of data and makes predictions through the analysis of related data .It tackles the problem of both uncertainty and limited certainty by bringing greater certainty .Equipped with the structural systematic sensing network,the interactive data-visualization and automation of decision-making,it makes retrospective and predictive data analysis .Decentralized governance means that public organizations take the democratic decision-making mechanism as the kernel,the public interests,and the dominant values .Big data ensures the diversity of participants,democracy and scientificity of decision making,and the fairness of participation and outcome . Smart public decision making is a new development of public decision-making theories and paradigms in the data-driven era .Smart public decision making should not only emphasize instrumental rationality,but also pay more attention to its practice and value rationality from the disciplinary perspective .As far as practice is concerned,smart public decision making should do more detailed analysis of the topic applicability of policies .As far as policy innovation,and the handling of public crisis and administrative supervision are concerned,smart public decision making has rare technological advantages .However,in other policy areas,its applicability is still in doubt .Will contradictions actually occur between the policy-making process as political gaming and its nature of profit sharing on one hand,and the application of the outcome of big-data analysis on the other ? How to guarantee the implementation of the policies ?All these questions need deeper research in order to provide guidance for practice .
