Abstract

This study aims to explore the scholarly advancements and research trends of living labs, highlighting their role as a strategic approach for addressing community challenges and driving innovation in public services through a systematic investigation of domestic academic research. A total of 510 research papers published between 2012 and 2024 were analyzed, focusing on unstructured data such as titles, abstracts, and keywords. Using text mining techniques, the underlying themes were systematically extracted and refined through Latent Dirichlet Allocation(LDA) topic modeling and semantic network analysis, leading to the identification of five core themes: ‘Smart cities and participatory innovation’, ‘Community welfare and social innovation’, ‘User-driven field-Based innovation’, ‘Educational innovation linked to community issues’, and ‘Enhancement of quality of life, culture, and youth welfare’. Each theme was named based on high-frequency terms within topic clusters and further verified through a detailed literature review, ensuring the thematic categories accurately reflect the focus of the papers. Semantic network analysis further revealed the structural interconnections between keywords, adding depth to the understanding of their unique characteristics. The findings present a comprehensive view of the research landscape in living lab studies, highlighting thematic convergence and divergence across various scholarly focuses. This study provides actionable insights for academics and policymakers, suggesting that living labs can serve as a strategic framework for solving regional challenges, enhancing community resilience, and integrating digital solutions into public services and lays the foundation for future research and policy initiatives aimed at leveraging living labs for sustainable community innovation.
