Digital Transformation and Macroeconomic Performance: An Empirical Investigation of Digital Payment Expansion and Economic Growth in India

Abstract

One of the most important structural changes of contemporary emerging economies is the spread of digital technologies. The present research is an attempt to analyze the relationship between digital payment expansion and macroeconomic growth in India using annual time series data from 2017-18 to 2024-25. The conceptual frameworks are based on the endogenous growth theory and transaction cost economics, and the real implementation of digital payment is the concrete indicator of the development of the digital ecosystem. Descriptive statistics reveal that the volume of digital transactions has grown exponentially from 2,070.89 crore transactions in 2017-18 to 22,831 crore transactions in 2024-25, a leap of over ten times in seven years. Conversely, real gross domestic product (GDP) growth was highly volatile, falling by 5.8 per cent during the COVID-19 pandemic (2020-21) and recovering strongly by 9.7 per cent in 2021-22. Bivariate correlations show a positive but not statistically significant relationship between total digital payment volume and annual real GDP growth (r =.31, p =.454, N = 8). This is also confirmed by a simple linear regression with digital payment volume explaining only 9.6% of the variance in GDP growth and not reaching conventional levels of significance (F = 0.717, p =.454). Such results do not diminish the economic importance of digitalization but rather demonstrate the insufficiency of a simple, one-metric analysis to understand complex, mediated relationships. The results show that digital transformation is not directly and immediately effective on the annual change in output but works through some indirect channels such as financial inclusion, productivity improvement, formalization and reduction in transaction costs. The research finds the benefits of sustainable development drawn from digitalization are dependent on further investments in human capital, cybersecurity frameworks, regulatory systems and inclusive infrastructure design.
