Abstract
This study investigates the adoption of online banking in Taiwan
by extending the Technology Acceptance Model (TAM) to incorporate trust,
perceived risk, and environmental, social, and governance (ESG) factors.
Drawing on survey data from 250 respondents and employing Structural Equation
Modeling (SEM), the research confirms that perceived usefulness and ease of use
remain critical determinants of behavioral intention. Trust emerged as a vital
mediator, while perceived risk negatively influenced adoption. Importantly, the
findings reveal that both perceived ESG and behavioral ESG practices
significantly shape customer trust, behavioral intention, and actual system
use, underscoring the growing role of sustainability in digital finance. The
results highlight a reciprocal relationship between perceived and behavioral
ESG, where customer perceptions incentivize banks to implement substantive ESG
actions. The study contributes theoretically by integrating TAM with
sustainability perspectives and offers practical insights for banks and
policymakers to promote secure, inclusive, and sustainable digital banking.
