近年来，推动社会治理的协同化、智能化，完善共建共治共享的社会治理制度，是国家的重要发展方向.数据作为一种生产要素，在社会治理中起着愈发关键的作用.如何实现多方海量数据的安全查询、协同管理、智能分析，是提升社会治理效果的关键问题.在新冠疫情防控等重大公共事件中，分布式社会治理面临着安全计算效率低、多方可信协同差、复杂任务决策难的三大挑战.针对以上挑战，基于安全多方计算、区块链技术与精准智能理论，提出了一种基于大数据的分布式社会治理智能系统.所提出的系统能够支撑社会治理的各类应用，为新时代社会治理水平的提升提供决策支撑.

In recent years, promoting the synergy and intelligence of social governance, and improving the social governance system of co-construction, co-governance and sharing are important development directions for the country. As a production factor, data plays an increasingly critical role in social governance. How to realize the secure query, collaborative management, and intelligent analysis of multi-party massive data is the key issue to improve the effectiveness of social governance. In major public events such as the prevention and control of the COVID-19, distributed social governance faces low computing efficiency, poor multi-party credible coordination, and difficult decision-making for complex tasks. In response to the above challenges, this study proposes on big data based distributed social governance intelligent system based on secure multi-party computing, blockchain technology, and precise intelligence theory. The proposed system can support various applications of social governance that provide decision-making support for the improvement of social governance in the new era.
