Using fossil fuel emits various types of pollution and greenhouse gas such as CO2, SO2 and NO2. Effective environmental policy is the important approach to enhance the environmental quality and reduce the energy consumption quantities. The environmental policy model based on endogenous growth theory is built in this paper. Both environmental quality control methods are considered into this model, the first is environmental tax，it is a kind of indirect environmental control policy. The other is the pollution governance investment. This is a kind of direct environmental policy. We propose different scenarios to simulate and analysis the effects of environmental tax and pollution governance investment. The results show environmental tax has a better response to double dividend hypothesis, and this approach also has better effecting than pollution governance investment. In order to make enterprises automatically reduce emission, increase energy efficiency and ultimately correcting market failures. The implement of environmental tax will not only reasonable transfer the social cost caused by the environmental pollution to the enterprises, but also enables enterprises to avoid facing too much taxes. The redistribution of the revenue collecting from environment tax also needs to be flexible in order to avoid aggravating the conduction effect of social injustice.
