Abstract:There is still a certain gap between China and foreign countries in terms of policies such as rainwater discharge fee management. Taking the high-tech parks with good economic and construction conditions as the object, the design of rainwater charging policies is studied, and the foreign rainwater discharge fee collection systems and calculation methods are studied and analyzed. Combined with the sponge city construction in high-tech parks, the suggestions are proposed from the aspects of rainwater charging target principles, rainwater fee calculation methods, incentive mechanisms, rainwater fee usage management, etc. to provide the support for the long-term management of rainwater in high-tech parks.
