Most available figures on Vietnamese research come from publication databases — which means they measure one sector reasonably and three sectors badly.
Knowing what the data misses is more useful than knowing what it contains.
What the data covers reasonably
- Output in internationally indexed journals.
- International co-authorship patterns.
- Growth trends in indexed publication over time.
- Fields where international publication is the norm.
What it misses systematically
- Vietnamese-language journal output.
- Technical reports and grey literature.
- Enterprise research and development entirely.
- Applied work that changes practice without producing papers.
- Training outcomes — where graduates go and what they do.
Interpreting a thin record
- A thin indexed record for a group may reflect coverage, not activity.
- This affects applied and locally focused researchers most.
- Check by asking directly rather than concluding from a search.
Comparisons that mislead
- Comparing output per researcher across countries with different sector mixes.
- Comparing fields with different publication norms.
- Using citation counts across languages.
- Attributing growth to policy when it partly reflects improved indexing coverage.
Better sources for specific questions
- National statistical publications for personnel and expenditure.
- Institutional reports for staffing and programme detail.
- Direct enquiry for anything about a specific group.
- Local colleagues for context that no dataset contains.
One thing worth remembering
Growth in indexed output partly reflects improved indexing coverage, not only increased activity.
Distinguishing the two requires knowing when journals were added to a database — and analyses that skip that step routinely overstate how much has changed.
Câu hỏi thường gặp
Where do most figures on Vietnamese research come from?
Publication databases, which means they measure one sector reasonably and three sectors badly.
What does the data cover reasonably?
Output in internationally indexed journals, international co-authorship patterns, growth trends in indexed publication, and fields where international publication is the norm.
What does it miss systematically?
Vietnamese-language journal output, technical reports and grey literature, enterprise research entirely, applied work that changes practice without papers, and training outcomes.
Which comparisons mislead?
Output per researcher across countries with different sector mixes, fields with different publication norms, citation counts across languages, and attributing growth to policy alone.
What does growth in indexed output partly reflect?
Improved indexing coverage rather than only increased activity — distinguishing the two requires knowing when journals were added to a database.
