Please note that the datasets provided herein also serve as the source for all remaining figures and visualizations beyond those explicitly listed. To ensure transparency and reproducibility in constructing the Task-based Skill Ratio (TSR), we provide intermediate data covering the entire process from occupational description matching to task attribute classification, including multi-source classification results from manual coding, GPT-5, and Gemini 2.5 Pro for robustness verification.","keywords":["Social Sciences","Age support ratio","Task-based Skill Ratio"],"license":"http://creativecommons.org/publicdomain/zero/1.0","datePublished":"2026-02-04","dateModified":"2026-03-25","includedInDataCatalog":{"@type":"DataCatalog","name":"Harvard Dataverse","url":"https://dataverse.harvard.edu"},"publisher":{"@type":"Organization","name":"Harvard Dataverse"},"version":"2.3","citeAs":"@data{DVN/YJVIOQ_2026,author = {Gu, Hengyu and Wu, Yingju and Marois, Guillaume and Lutz, Wolfgang and Niu, Tianlong},publisher = {Harvard Dataverse},title = {China's demographic dividend has moved from age-based labor supply to skill-based productivity},year = {2026},url = {https://doi.org/10.7910/DVN/YJVIOQ}}","distribution":[{"@type":"cr:FileObject","@id":"ASR_TSR_Replication_Data.zip","name":"ASR_TSR_Replication_Data.zip","encodingFormat":"application/zip","md5":"da2abab18e723b310a9d16b742a89c64","contentSize":"1386191","description":"","contentUrl":"https://dataverse.harvard.edu/api/access/datafile/13444760"},{"@type":"cr:FileObject","@id":"Note.docx","name":"Note.docx","encodingFormat":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","md5":"10ddcbbb352c5796e65fc3e01604ebdb","contentSize":"14143","description":"","contentUrl":"https://dataverse.harvard.edu/api/access/datafile/13433048"}]}
