Factors Influencing Consumer Upcycling Behavior—A Study Based on an Integrated Model of the Theory of Planned Behavior and the Technology Acceptance Model

In the context of the global climate change debate, changing consumer awareness and guiding them towards sustainable lifestyles should be key considerations. This study investigates the factors influencing consumers’ upcycling behaviors by conducting research and collecting 336 valid questionnaires at the “Eco Blet” sustainable design exhibition and workshop held at Livat Beijing (Ingka Centres Beijing). The survey results revealed that consumers’ upcycling behavior is significantly influenced by subjective norms, perceived behavioral control, perceived usefulness, and attitudes. In addition, individuals with higher levels of education and those with annual incomes of less than 100,000 RMB and more than 400,000 RMB are more likely to engage in upcycling. The empirical analysis of consumer upcycling behavior is conducted using structural equation modeling (SEM), and the theory of planned behavior (TPB) and technology acceptance model (TAM) are integrated into a comprehensive framework. This research provides both theoretical support and practical insights for promoting sustainable consumer behaviors, contributing significantly to carbon emission reduction.
