Supplementary Materials S1–S6: Workforce Capabilities Across Twin-Transition Policies in Five Southeast Asian Countries

This supplementary dataset accompanies the manuscript entitled "Workforce Capabilities Across Twin-Transition Policies: A Comparative Document Analysis of Five Southeast Asian Countries with a Focus on Vietnam." The study examines eight workforce-capability dimensions across 20 selected national digital, AI, workforce/skills, and green-transition policy documents from Vietnam, Singapore, Thailand, Malaysia, and Indonesia. The supplementary package contains six components: S1 — Complete Coding Matrix and Evidence Anchors. The full set of 160 document-by-capability coding judgements, including classification statuses and supporting evidence. S2 — Operational Codebook and Coding Decisions. Definitions, inclusion and exclusion criteria, coding thresholds, boundary decisions, and source-anchored illustrative coding examples (S2.3; formerly Appendix B). S3 — Document Profiles and Source Provenance. Document characteristics, genres, languages, editions, provenance information, and the complete 20-document primary-policy source register (S3.3; formerly Appendix A). S4 — Sensitivity Analyses. Source-selection, document-vintage, and classification-threshold diagnostics. S5 — Document Currentness and Eligibility Audit. Revision-stage screening of policy instruments, source-currentness considerations, and document-selection decisions. S6 — Expected-Domain Mapping and Cross-Domain Articulation. The descriptive mapping used to distinguish capability articulation within and outside expected policy domains. The final coding matrix contains 79 Explicit–Central, 40 Explicit–Peripheral, 12 Adjacent/Implicit, and 29 Not Identified judgements. The expected-domain analysis identifies 55 explicit classifications among 95 off-domain opportunities. These materials are provided to improve the transparency, auditability, and reproducibility of the document-level analysis. The classifications do not constitute measures of policy implementation, effectiveness, or administrative integration between instruments. The creator metadata is temporarily anonymised as "Anonymous" to preserve double-blind peer review. Following acceptance of the associated manuscript, the record will be updated to identify the authors accurately. The supplementary materials are made publicly accessible to support scholarly verification.
