经济增长模型中政府支出的生产效应分析

Using general production function,this paper discussed the production effect of government expenditure and fiscal policy,and got the following conclusions:when the production function is increasing return to scale ,the model becomes a model ,if the income tax rate is big the economic growth rate is small ,and if customers are more patient and the outside production effect of government expenditure is big, the economic growth rate is big too; when the production function is decreasing return to scale,the equilibrium point is saddle ,if the income tax rate is big the equilibrium values are small ,and if customers are more patient and the outside production effect of government expenditure is big, the equilibrium values are big too; when the production function is increasing return to scale, the equilibrium point is unstable.
