Trust Formation Mechanisms in E-commerce Transactions: A Multidimensional Perspective

Abstract

Trust is a cornerstone of successful electronic commerce (e-commerce) transactions, where buyers and sellers interact in the absence of physical presence. Unlike traditional retail, where trust is established through interpersonal cues and tangible verification, e-commerce relies heavily on digital signals, technological assurances, and institutional mechanisms. This study investigates the multidimensional trust formation mechanisms that influence consumer participation in online transactions. Drawing upon Trust Theory, Technology Acceptance Model (TAM), and Signaling Theory, the paper develops an integrative framework explaining how website quality, vendor reputation, security infrastructure, social proof, and institutional assurance jointly shape consumer trust. A conceptual model is proposed and empirically tested through a survey of 412 online consumers. Structural Equation Modeling (SEM) reveals that perceived security, reputation, and social proof significantly influence trust, which in turn strongly predicts purchase intention. The study contributes to both theory and practice by offering a holistic explanation of trust formation in digital marketplaces
