E-Commerce Expansion in India: Emerging Trends, Growth Drivers, and a Regression-Based Empirical Analysis (2016–2023)

Abstract: The e-commerce industry in India has experienced a transformational growth in 2016-2023, which has been triggered by the explosive adoption of smartphones, the widespread adoption of digital payment infrastructure and a post-pandemic seismic change in consumer buying behavior. In this research, the authors examine the scale and the factors of e-commerce development in India throughout this eight-year sample based on secondary panel data in IBEF, NASSCOM, RBI, and Statista. Using Ordinary Least Squares (OLS) multiple regression analysis and Compound Annual Growth Rate (CAGR) computation and Pearson correlation matrix, the study measures the relative impact of internet users, smartphone penetration, digital payment volumes, and the density of logistics network on gross e-commerce revenue. Findings indicate that the total CAGR of the study period is 27.4% and that the strongest positive determinants of sectoral revenue are digital payments and smartphone penetration. The null hypotheses are both rejected at the 1% level and confirm the strength of the empirical results. The article also breaks down market share by category - fashion, electronics, groceries, financial services, and travel - in order to shed light on structural changes. Discussed are policy implications of regulators, logistics providers and digital marketers.
