Abstract
The importance of individual consumption behavior in a low-carbon economy is gradually recognized. Social norms have a significant effect on individual purchase behavior. However, the influence mechanism of social norms still needs more research. We conducted two behavioral experiments to explore the specific factors: first, the effect of descriptive norms on personal low-carbon consumption behavior through feedback information, and second, a comparison with injunctive norms, focusing on the impact of the normative focus shift brought by punishment represented by the policy implementation. The results show that social norms can effectively promote individual low-carbon consumption through feedback and high policy implementation efficiency. In particular, after effective policy implementation becomes an inherent element of injunctive norms, injunctive norms are activated and become the focus of norms, significantly improving the purchase rate of low-carbon goods.
