It also examines the impact of perceived threat, perceived value, and perceived efficacy on subjective norms, behavior attitudes, and behavior intentions. Among them, it perceived threats consist of two dimensions: perceived severity and perceived vulnerability; Perceived efficacy consists of two dimensions: self-efficacy and reactive efficacy; Perceived value consists of four dimensions: Environmental Values, social value, spiritual value, and cost value. This research has found that: (1) Perceived threats positively affect behavioral intentions; (2) Perceived value positively affects behavioral intention; (3) Perceived efficacy positively affects behavioral intention; (4) Subjective norms have a partial mediating effect on perceived efficacy, perceived value, behavioral attitude, and behavioral intention; (5) Behavioral attitudes have a partial mediating effect on perceived threat, perceived efficacy, perceived value, and behavioral intention.
