| Summary: | 碩士 === 國立臺灣大學 === 健康政策與管理研究所 === 101 === Purpose: Current environmental deterioration and ecological devastation are widely attributed to the misconduct of human beings. Researchers have proposed the concept of “environmental behavior” since 1970s to study behavioral determinants of environmental problems and have further emphasized the implementation of environmental practices in various aspects of daily life. This study aims to examine the relationship between environmental concerns and environmental behaviors, and the role self-efficacy may play to affect their relationship.
Methods: The Data on which this study was based came from “2010 Taiwan Social Change Survey.” Bivariate analyses were carried out to examine the associations among sociodemographic characteristics, environmental concerns, self-efficacy and environmental behaviors. Multiple Poisson linear regression and logistic regression were then used to analyze two domains of environmental behavior: resource-saving and resource-recycling, respectively. Finally, the analysis was proceeded to confirm the mediator role of self-efficacy, between environmental concerns and environmental behaviors.
Results: The main findings were:(1) Participants with the following characteristics were more likely to engage in environmental behaviors: female, 45~64 year-old, living in the northern part of Taiwan, achieving the highest educational level (university and above) and belonging to Hakka ethnic group, (2) The two dimensions of environmental concerns: “valuing natural environment” and “willingness to pay for environmental conservation” were both significant predictors of “resource-saving” as well as “resource-recycling” behaviors, and (3) Self-efficacy was not the mediator between environmental concerns and environmental behaviors.
Conclusions: Environmental concern could predict environmental behaviors but without being mediated by self-efficacy. It is possible that the environmental behaviors examined in this study are relatively easy for people to carry out that self-efficacy is no long an issue. It may be also due to the insufficient content validity resulted from the single-item measurement or the item included was related to other variables which were not measured in this study. The significant predictive power of “environmental values” and “willingness to pay” suggest the vital importance in cultivating pro-environmental values among the general public as the fundamental strategy in environmental protection policy.
