Human Capital Investment, Technological Adoption, and Economic Growth in India: An Empirical Analysis through the Lens of SDG 8

This paper empirically examines the association between human capital investment, technological adoption, and economic growth in India within the framework of Sustainable Development Goal 8 (SDG 8), which advocates sustained, inclusive, and sustainable economic growth, full and productive employment, and decent work for all. Using secondary annual time-series data spanning 2000 to 2022, sourced from the World Bank, Reserve Bank of India (RBI), Ministry of Statistics and Programme Implementation (MoSPI), UNESCO, and the International Labour Organization (ILO), the study estimates an Ordinary Least Squares (OLS) regression in levels, validated by an Engle–Granger cointegration test, to investigate the relationship between GDP per capita growth (the dependent variable) and gross tertiary enrolment, public expenditure on education, internet penetration, research and development (R&D) expenditure, gross fixed capital formation, labour force participation, and trade openness. Given the small sample (n = 23) and mixed orders of integration, the paper explicitly justifies the static level specification relative to ARDL, ECM, and VAR alternatives, whose parameter requirements exceed the available degrees of freedom, and supplements the baseline model with a parsimonious specification, a lagged-regressor specification, and a COVID-19 exclusion check. The results indicate that tertiary enrolment, R&D expenditure, and internet penetration are positively and statistically significantly associated with per capita growth, while gross fixed capital formation and labour force participation also display meaningful positive associations. Coefficient magnitudes are interpreted on within-sample scales — in particular, the R&D coefficient is read per 0.1 percentage point of GDP — and standardized coefficients are reported to separate statistical significance from substantive importance. The findings are consistent with endogenous growth theory and human capital theory, and are interpreted strictly as conditional associations rather than causal effects. The analysis also foregrounds India's structural labour market constraints — pervasive informality and depressed female labour force participation — as central to the decent-work dimension of SDG 8.
