As fundamental units of smart cities, smart communities serve as micro-scale carriers for the application of smart technologies in spatial governance and as critical entry points for refined urban management. While the technology-driven approach has improved administrative efficiency, challenges persist in aligning technological applications with residents' needs, particularly in improving their overall well-being. This study examines how spatial optimization strategies can enhance the well-being of residents in smart communities from the perspective of transitioning "from intelligence to livability". This study employs semantic analysis, integrating text mining and natural language processing (NLP) techniques, to examine policy documents on smart communities in China and user-generated content from online platforms. By extracting keywords and themes related to spatial optimization, residents’ needs, and livability enhancement, the study identifies core concepts and strategic models. Based on these findings, it constructs a four-dimensional interaction model—People, Technology, Space, and Environment—to explore the coupling mechanisms among these elements. Additionally, representative smart community cases are analyzed to assess spatial optimization strategies across these four dimensions. Finally, considering China’s smart community development needs, this study proposes localized spatial optimization pathways, aligned with national conditions, aiming to enhance livability through inclusive and sustainable spatial strategies. The findings indicate that: (1) enhancing residents’ well-being requires moving beyond a technology-centered model of convenience toward spatial emotional empowerment, emphasizing social support and psychological belonging; (2) spatial optimization should balance technological efficiency with human-centered values through mixed-use layouts, age-friendly design, and digital participation platforms; and (3) sustainable design should integrate green infrastructure optimization, the adoption of low-carbon smart technologies, and the enhancement of ecological interactive spaces, ensuring the long-term livability and environmental adaptability of smart communities. This study provides theoretical insights and practical guidance for smart community planning and development, contributing to the creation of more inclusive and sustainable livable smart communities.
