Constructs

rd_expenditure_gdp_pct R&D Expenditure as % of GDP

Gross domestic expenditure on research and development as a percentage of gross domestic product

patent_applications_per_million Patent Applications Per Million

Number of patent applications filed per million population at national and international patent offices

researchers_per_million Researchers Per Million

Full-time equivalent researchers engaged in R&D per million population

high_tech_exports_pct High-Tech Exports Share

High-technology exports as a percentage of total manufactured exports based on OECD SITC classification

scientific_publications_per_capita Scientific Publications Per Capita

Number of citable scientific and technical journal articles per million population per year

total_factor_productivity_growth Total Factor Productivity Growth

Annual growth rate of total factor productivity measuring technological progress and efficiency gains

Findings

R&D expenditure as share of GDP is positively associated with TFP growth with estimated social returns 2-4 times larger than private returns to R&D investment

Direction: positive Confidence: strong Method: ols_regression

Patent applications per capita are positively associated with GDP per capita growth but with heterogeneous effects across technology sectors and country income levels

Direction: conditional Confidence: moderate Method: ols_regression

Researcher density per million population is strongly positively correlated with scientific publication output per capita across 140 countries

Direction: positive Confidence: strong Method: correlation_matrix

High-technology export share is positively associated with economic complexity and long-run growth in Schumpeterian growth models with empirical validation

Direction: positive Confidence: moderate Method: ols_regression

Temporal scope: 1996-present | Population: Countries worldwide

Key Findings

  • R&D expenditure as share of GDP is positively associated with TFP growth with estimated social returns 2-4 times larger than private returns to R&D investment (positive, strong)
  • Patent applications per capita are positively associated with GDP per capita growth but with heterogeneous effects across technology sectors and country income levels (conditional, moderate)
  • Researcher density per million population is strongly positively correlated with scientific publication output per capita across 140 countries (positive, strong)
  • High-technology export share is positively associated with economic complexity and long-run growth in Schumpeterian growth models with empirical validation (positive, moderate)
