摘　　要：研究小型开放经济体中资本税收政策对宏观经济变量的影响.建立一个具有柯布—道格拉斯生产函数和外生技术进步的经济模型,分析股利所得税、资本所得税、企业所得税等3种不同类型的资本税收政策如何影响社会投资、经济增长和福利水平.结果表明:①资本税收的引入导致了扭曲效应,代表性企业的现值随企业所得税税率的提高而下降;②最优资本存量是世界市场资本净回报率、企业所得税税率、股利所得税税率的递减函数;③如果资本调整成本较小,资本收敛速度加快,如果资本调整成本足够大,资本收敛速度是企业所得税和股利所得税税率的递增函数,是资本所得税税率的递减函数;④资本税收税率上升具有两种效应,一是导致新的稳定状态下资本存量和工资水平均下降,从而导致个人未来消费水平下降,二是税收收入增加使得一次性转移支付收入增加,政策调整的净效应取决于二者的力量对比.In order to study the impact of capital tax policy on macroeconomic variables in small open economies,an economic model with Cobb-Douglas production function and exogenous technological progress is established in this paper,and how three different types of capital tax policies(dividend income tax,capital income tax and enterprise income tax)affect social investment,economic growth and socialwelfare levelis analyzed.The results show that the introduction of capital tax leads to adistortion effect,and the present value of representative enterprises decreases with the increase of enterprise income tax rate;thatthe optimal capital stock is a decreasing function of net return on capital,enterprise income tax rate and dividend income tax rate in the world market;that if the cost of capital adjustment is small,the speed of capital convergence will accelerate,andif capital adjustment is big enough,capital convergence rate is an increasing function of enterprise income tax rate and dividend income tax rate and a decreasing function of capital income tax rate;and that the increase of capital tax rate has two effects:one is that it leads to the decrease of capital stock and wage level under the new stable state,and the other is that the increase of tax revenue causes the increase inone-time transfer payment,the net effect of policy adjustment depending on the relativestrength of the two.
