Cumulative Advantage and Spatial Friction in Urban-Tourism Knowledge Production: Longitudinal Evidence from China-Affiliated Institutional Collaboration, 2011–2025

This dataset supports the manuscript “Cumulative Advantage in Scientific Collaboration: Longitudinal Evidence from Tie Formation and Persistence under Bibliographic Coverage Instability.” It contains the processed bibliographic, institutional-network, geographic-opportunity, longitudinal dyadic, statistical-model, and supplementary materials used to examine China-affiliated urban-tourism research indexed by OpenAlex from 2011 to 2025.The archived retrieval contained 61,332 unique candidate works.

A frozen, fully automated eligibility procedure was applied to the same candidate checkpoint to construct a strict primary corpus of 1,333 works, an expanded sensitivity corpus of 1,824 works, and a balanced-source sensitivity cohort of 130 works from 13 sources. No manual eligibility labels were used in the final robustness analysis.The repository package includes the complete candidate-level automated screening audit and screening reasons; strict, expanded, and balanced-source corpus files; work–institution and institution metadata; period-specific network edge and node tables; geographic opportunity data; opportunity-adjusted distance summaries; longitudinal dyad risk sets for new-tie emergence and tie persistence; standardization parameters; pooled and post-break regression outputs; model-status and optimizer diagnostics; robustness summaries; retrieval-query metadata; the frozen screening rulebook; run manifests and checksums; analysis/reproduction scripts; software requirements; and all manuscript-relevant Supplementary Tables S1–S13 and Supplementary Figures S1–S3.The data support reproducibility of the reported analyses of cumulative institutional advantage, spatial friction, collaboration-network development, tie formation, and tie persistence.
