Abstract: It is an important part of the proactive fiscal policy to implement structural tax cuts, promote the tax reform, reduce the tax burden by means of tax cuts, rebates or credits, and promote the investment by enterprises and the consumption by individuals. This paper first constructs a computable general equilibrium model in line with China's tax structure, then uses this model to simulate the impact of China's structural tax cuts on the social output in recent years, and finally applies the counterfactual simulation to select the optimal structural tax cuts. The research finds that structural tax cuts do not always boost the economy, which is reflected in the following: (1) The three VAT cuts have a positive effect on the social output; (2) The increase of the individual income tax exemption has a negative effect on the social output; (3) The small and micro enterprise income tax exemption has a positive effect on the social output; (4) When the total amount of the tax reduction is the same, the tax reduction for VAT and the corporate income tax and the structural tax reduction policy for the individual income tax increase can maximize the social output.
