Fiscal and taxation policy is an important means for a country to macroscopically regulate and control its economy. Currently, due to insufficient financial support, lack of specialized credit institutions, and weak systematicness and integrity, it is difficult to fully play the role of stimulation and promotion for circular economy development and construction of a resource saving and environment friendly society. Regarding the taxation system, due to the absence of the main taxes of resources and environment protection, and uncoordinated taxation policies, and the unreasonably, unsystematically and incomprehensively preferential taxation policy has resulted in the fact that the taxation system is difficult to effectively promote circular economy development and construction of a resource saving and environment friendly society. We must innovate the fiscal and taxation system in China, and embody the concept of circular economy development, so as to build and perfect the target of an environment finance policy system and green taxation system.
