| Summary: | 博士 === 國立雲林科技大學 === 設計學研究所 === 106 === This study aims to understand the psychosocial factors of the young working poor buying green home appliances and how to implement the Design for Sustainable Behavior (DfSB) strategy in the product design process. Sustainable consumption and production must be considered at the same time to increase the practice of perpetual behaviors of the young working poor. Furthermore, the importance of the DfSB product evaluation tool is highlighted based on the problems of DfSB. Its feasibility and rationality can be detected through case studies to make product design more appropriate.
This study proposed three research subjects, and the research objects were young designers with a working poor background and young working poor. First, the behavioral model of purchase intention of green household appliances was developed based on the extended theory of planned behavior (ETPB). The structural equation modeling (SEM) analysis results show that subjective norms, lifestyle, environmental concerns, and DfSB methods directly affect the purchase intention of this group, whereby subjective norms are the strongest impact factor, and ecological cues are the best product design method for this group. Second, the DfSB assessment tool and product design strategies that promote sustainable behavior of the young working poor are constructed through Kelly Reporty Grid Technology (RGT), which is based on the limitations of general product design that influence people's sustainable behavior. Through cluster and principal component analyses, three strategy types were proposed that correspond to different product features, suggestions, and guidance. In addition, the effectiveness and potential of an assessment tool were demonstrated using the Wilcoxon rank test.
Finally, this study set up an integrated framework of sustainable product development and promotion of sustainable behavior strategies for the young working poor based on the above results and related research, demonstrating the process of sustainable production and consumption patterns. Design researchers and green marketing can plan effective and sustainable design programs to induce the sustainable behavior of the young working poor in the use of household appliances, as well as to link the benefits of sustainable production and consumption through strategies and the assessment tool. The transformation of social technology systems and practice opportunities of people’s daily life will also increase.
