Structural Fractures in the Scaled Diffusion of the Low-Altitude Economy: A Bibliometric Diagnosis and Collaborative Governance Framework

This dataset supports the study: Structural Fractures in the Scaled Diffusion of the Low-Altitude Economy: A Bibliometric Diagnosis and Collaborative Governance Framework. The dataset contains the data tables and visualization outputs used for a bibliometric analysis (CiteSpace-based). It covers bibliographic coupling, reference co-citation, and co-occurrence networks (keywords, authors, journals, institutions, and countries), as well as clustering, timeline views, and burst detection results. These materials enable replication of the knowledge structure diagnosis, fragmentation patterns, and collaboration mapping reported in the paper. Contents CSV files: network data tables (e.g., adjacency tables, node/edge data) for bibliographic coupling, co-citation, and co-occurrence analyses. XLSX files: processed/cleaned keyword tables, publication count summaries, and clustering outputs with year information. PNG/JPG files: figures exported from CiteSpace (e.g., co-occurrence maps, clustering results, timeline views, burst detection plots), plus chord and Sankey diagrams. GML file: country map file used for network visualization. OPJU file: the original plotting/project file for the publication-count figure. How to use CSV/XLSX files can be opened with Excel, R, or Python. Network tables and the GML file can be imported into CiteSpace or Gephi for visualization and further analysis. Image files contain the visualization outputs referenced in the manuscript.Keywords: Low-Altitude Economy; Urban Air Mobility; Innovation Ecosystems; Knowledge Fragmentation; Regulatory Lag; Socio-technical Transitions; Bibliometric Analysis; Collaborative Governance
