Environmental regulations are an effective means to restrict the negative externalities of environmental pollution from green technology innovation. A reasonable measurement of its impact on green technology innovation is the key to balancing economic development and environmental protection. The article selects 30 provincial panel data in my country from 2009 to 2017, and uses the panel threshold model to analyze the impact of environmental regulations on green technology innovation. The study found that: environmental regulations can effectively promote the level of green technological innovation; environmental regulations have a significant threshold effect on green technological innovation. As the intensity of environmental regulations increases, its promotion of green technological innovation has a marginal effect; environmental regulations have a diminishing effect on the level of green technological innovation. The optimal intensity interval is below 1.261.
