Abstract: This article introduce consumption tax, capital gains tax, labor income tax and enterprise income tax into the dynamic stochastic general equilibrium (DSGE) model. We use the Bayes Estimation method to estimate the dynamic parameters. In this paper, we try to analysis four kinds of taxes impact on household consumption, employment and household consumption rate. First, reduce the consumption tax can not only increase household consumption and household consumption rate, but also can increase the employment. Second, improve the capital gains tax may reduce household consumption, however, can promote employment and increase household consumption rate. Third, reduce the labor income tax can significantly improve household consumption and employment, but have small impact on improve household consumption rate. Fourth, improve the enterprise income tax may reduce household consumption and employment, but can increase household consumption rate.
