Abstract: Combining the theory of planned behavior, this paper took high-end manufacturing companies as the example to explore the relationship between different types of environmental regulations, green technology innovation intention and green technology innovation behavior. Using hierarchical regression analysis, the results showed that command and control type environmental regulation and market-based incentive environmental regulation have significant direct positive effects on green technology innovation intention and behavior, in which the effect of command and control type environment regulation on green technology innovation intention is greater, the effect of market-based incentive environmental regulation on green technology innovation behavior is greater, and green technology innovation intention has a significant direct positive impact on green technology innovation behavior. The findings also suggested that green technology innovation intention plays different mediating roles in different types of environmental regulation and green technology innovation behavior, that is, it fully mediates the relationship between command and control type environmental regulation and green technology innovation behavior, while partially mediates the relationship between market-based incentive environmental regulation and green technology innovation behavior. The results uncovered the reasons that exists in the phenomenon of “incomplete regulation” and found the mediator variable which further supports the “Porter hypothesis”.
