智慧社会是数字中国建设的重要组成部分，而相关建设面临着现实挑战；研究智慧社会体系化建设方法，将支持构建国家竞争新优势、推进中国式现代化、实现数字中国战略。本文围绕如何构建新型智慧社会、实现社会资源效益最大化的主旨，分析了智慧社会建设现状并概括了发展趋势，凝练了当前存在的分散建设投资大、运营效率低、发展不平衡等突出问题；基于系统工程方法，提出了智慧社会体系化建设的总体架构，即采用“1+N+X”智慧社会业务应用体系化建设新模式，以统筹全社会信息基础设施资源、共建智慧社会体系能力支撑平台为重点，据此扩展各类业务应用。研究建议，加强顶层设计，共建“网、云、数、控、智”一体的体系能力支撑平台，形成智慧社会体系化建设基础数字底座；采取体系化建设新模式，以高效运营推动智慧社会建设持续发展；配套改革举措，构建完善的智慧社会标准和法律法规体系；以国家级智慧社会数字化系统工程实验室的形式，为智慧社会体系化建设提供坚实的理论、技术、人才支撑。

A smart society is an important component of the digital China strategy; however, the construction of the smart society currently faces practical challenges. Studying a systematic construction method for the smart society will cultivate new competitive advantages for China, promote Chinese path to modernization, and realize the digital China strategy. This study aims to explore methods for building a new type of smart society and maximizing the benefits of social resources. It analyzes the current status and development trends of smart society construction and summarizes the prominent problems including large investment in decentralized construction, low operational efficiency, and uneven development. Following a systems engineering method, an overall architecture for the systematic construction of the smart society is proposed. The architecture adopts a new “1+N+X” model that focuses on coordinating information infrastructure resources of the entire society to build a smart society system capability support platform, thus to expand various business applications accordingly. Moreover, we propose the following suggestions: (1) strengthening top-level design to build a system capability support platform that integrates network, cloud, data, control, and intelligence, thereby forming a basic digital base for the smart society; (2) adopting a new model of systematic construction to promote the sustainable development of smart society construction through efficient operation; (3) establishing a comprehensive standards and regulations system for the smart society; and (4) providing solid theoretical, technical, and talent support for the systematic construction of the smart society by building a national laboratory for digital systems engineering of the smart society.
