Summary
Gross national product (GNP) per capita and research and development (R&D) expenditure are key drivers of global biomedical research productivity. Investing in these areas can significantly boost scientific output worldwide.
Area of Science:
- Biomedical research
- Bibliometrics
- Health economics
Background:
- Global variations in biomedical research productivity exist.
- Understanding factors influencing research output is crucial for scientific advancement.
Purpose of the Study:
- To identify key socio-economic factors associated with international differences in biomedical research productivity.
Main Methods:
- Analysis of biomedical research articles published between 1990-2000 from the MEDLINE database.
- Normalization of article counts by population per year for each country.
- Multiple and simple linear regression models using 10 socio-economic indicators.
Main Results:
- Gross National Product (GNP) per capita and Research and Development (R&D) expenditure were significant predictors of biomedical research productivity per capita.
- Most socio-economic indicators showed a significant relationship in simple regression analyses.
Conclusions:
- Increasing biomedical research output necessitates focusing on enhancing GNP per capita and R&D expenditure.
- These two factors are the most impactful for stimulating national scientific productivity.
