The development of new energy is not only an objective need for sustainable development of mankind, but also an important breakthrough for the world to foster new economic growth points. The focus of this article is on what kind of fiscal and tax policies the government implements can better guide the development of new energy and have a more favorable impact on the economy. This paper, taking wind power and solar photovoltaic power industries in the Inner Mongolia as an example, using the dynamic 3ED-CGE model, explored the economic impacts of different financial subsidies and preferential tax policies on new energy enterprises. And then this paper provided suggestions for the formulation of fiscal and tax policies. The study founded that compared with the fixed subsidy mechanism financial subsidies by the fall-off mechanism could be better to promote the growth of GDP, residents' welfare and employment. If the government didn't subsidize the new energy electric power's sales price to network after 2020, it would not have a negative impact. The 15% income tax rate was more effective in promoting the development of economic than 25%. 8.5% and 6% value-added tax rate exerted similar effects on the economy, but 6% value-added tax rate had a significant promotion on optimized adjustment the consumption structure of fossil energy and electric energy.
