In order to analyze the effects of active fiscal policy implemented in China in the context of tax and fee reduction, this paper adopts a dynamic stochastic general equilibrium model with microeconomic foundations to study the economic effects of fiscal policy based on a comprehensive consideration of the previous literature. The empirical study based on Matlab software finds that: first, active fiscal policy has a boosting effect on the economy and can stimulate the level of output to rise in the short run; second, different fiscal policy instruments have different impact mechanisms on economic variables, and the impact paths of government consumption spending and investment spending are completely inconsistent; third, the economic effects of government tax cut policies are better than government spending policies, and structural tax cut policy is softer than universal tax cuts; fourth, expansionary government investment spending has the most significant effect on output stimulation and has a very long-term impact on output level. Through the above model analysis, this paper argues that fiscal policy should play a greater role in supporting industrial restructuring, giving full play to the long-term advantages of the interest rate effect on the basis of satisfying society’s short-term needs and pursuing prosperous economic development, increasing investment in public resource areas, deepening industrial structural reforms, offsetting negative supply shocks brought by trade frictions and cross-border investment, raising long-term output levels and increasing employment opportunities.
