一句话：通过三级综述系统整合智慧城市 SoS 治理的二次文献，揭示全球南方语境下的研究缺口与地理偏倚。
智慧城市已演化为融合物理基础设施、数字平台与社会过程的复杂系统之系统（SoS），其治理面临严峻挑战；而在社会经济条件、制度能力、基础设施缺口与包容性动态上，全球南方与全球北方差异显著，现有治理知识未必适用。本文开展三级综述，系统整合关于智慧城市治理的既有二次综述，聚焦识别全球南方特有的研究缺口。方法上遵循 PRISMA 流程保证文献筛选的严谨性，采用设计科学研究（DSR）指导概念性与构造性人工制品的构建，并用目标—问题—度量（GQM）模型组织数据抽取与分析。初步发现包括：研究存在明显偏向高收入地区的地理偏倚；对情境敏感的治理框架关注不足；数字孪生、DAO/Decidim 等参与式平台整合薄弱；缺乏针对全球南方定制的治理机制。预期贡献是提出细化的研究议程与结构化方法路径，支撑欠代表地区智慧城市 SoS 治理的后续研究。
Smart cities have evolved into complex systems‑of‑systems (SoS), integrating physical infrastructures, digital platforms, and social processes. Governing such systems poses critical challenges, particularly in the Global South, where socio‑economic conditions, institutional capacity, infrastructural gaps, and inclusion dynamics differ substantially from the Global North. This research conducts a tertiary review to systematically synthesise existing secondary reviews on smart-city governance, with a focus on identifying research gaps specific to the Global South. The study follows the PRISMA methodology to ensure rigor in article selection and employs Design Science Research (DSR) to guide the creation of conceptual and constructive artifacts. Additionally, the Goal-Question-Metric (GQM) model structures data extraction and analysis. Preliminary findings reveal a strong geographic bias toward high-income regions, limited attention to context-sensitive governance frameworks, weak integration of participatory platforms such as digital twins and DAO/Decidim, and a lack of governance mechanisms tailored to the Global South. Expected contributions include a refined research agenda and a structured methodological pathway to support future studies in SoS governance for smart cities in under-represented regions.
