Abstract
This study applies the Theory of Planned Behavior (TPB) to examine
how environmental education affects consumers’ willingness to purchase organic
agricultural products. A questionnaire survey of 266 participants in Tainan
City, Taiwan, provided the data for analysis using structural equation modeling
(SEM). The results show that attitude, subjective norms, and perceived
behavioral control each have a significant and positive influence on behavioral
intention. Among these, attitude has the strongest impact, suggesting that
favorable evaluations of organic products and greater environmental awareness
are key factors shaping consumers’ willingness to buy them. Based on these
findings, several practical implications are proposed. Public agencies and
schools may strengthen environmental education programs to cultivate
sustainable consumption habits. Businesses should emphasize transparent
information and credible green marketing to increase consumer trust. In
addition, policy support, such as financial incentives or better market access,
could reduce barriers to purchasing organic products and promote more
sustainable consumer behavior.
