Digital Payment Adoption in E-Commerce: Determinants, Barriers, Rural Digital Transformation, AI Integration, and Policy Dimensions

Abstract

The rapid expansion of electronic commerce has been intrinsically linked with the evolution of digital payment ecosystems. Platforms such as National Payments Corporation of India-operated Unified Payments Interface, mobile wallets, debit and credit cards, internet banking systems, and AI-enabled payment gateways have transformed transactional architectures in both urban and rural economies. Despite accelerated growth, digital payment adoption remains uneven across socio-economic, geographic, and demographic segments, particularly in emerging and rural markets.

This upgraded scholarly study develops a multidimensional conceptual framework integrating technological, psychological, institutional, policy, and sustainability dimensions to examine determinants influencing digital payment adoption within e-commerce ecosystems. Drawing from Technology Acceptance Theory, trust-security frameworks, financial inclusion theory, and digital transformation paradigms, the study incorporates artificial intelligence (AI) readiness, rural digital infrastructure, and regulatory support as extended determinants.

Primary data were collected from 300 online shoppers using structured questionnaires. Advanced statistical tools including reliability testing, exploratory factor analysis (EFA), correlation, multiple regression, chi-square testing, and structural interpretation were applied. Findings indicate that perceived security and trust remain the strongest predictors of adoption, while digital literacy, AI-enabled fraud detection confidence, income level, and rural infrastructure accessibility significantly moderate adoption intensity. Policy support and sustainability awareness also influence consumer trust formation.

The study contributes to fintech adoption literature by integrating AI inclusion, rural digital transformation, sustainability alignment, and policy governance into a unified empirical framework. It concludes that inclusive digital ecosystems, strengthened cybersecurity architecture, AI-driven trust reinforcement, and targeted rural financial literacy programs are essential for sustainable digital commerce expansion.
