Based on the planned behavior theory and social learning theory, this study constructs a model of “Error Management Culture” for regulating the relationship between “self-regulation” and “voluntary green behavior” with “green self-efficacy” as the intermediary, then clarifies the generation mechanism of employees voluntary green behavior. On the basis of convenient sampling, it uses hierarchical regression analysis and other methods for data analysis and hypothesis testing. The results show that the promoting regulatory focus has a positive and significant predictive effect on voluntary green behavior, while the defensive regulatory focus has the opposite effect. Green self-efficacy plays a partial mediating role in the above variable relationship. With green self-efficacy as the mediating variable, error management culture regulates the relationship between promoting regulatory focus / voluntary green behavior and defensive regulatory focus / voluntary green behavior respectively. On this basis, this article puts forward some suggestions.
