稳定国际外汇市场的税收思考─—简单托宾税及改进方案设想

My Tax Consideration to Stabilizing the Foreign Exchange Market

税基与税率的确定问题、应税交易种类范围的界定及收入分配问题的存在，表明简单托宾税的可操作性不够，因而没有现实可行性。两级托宾税则拥有如下优点：不影响资本的流动性，却能有效打击投机；通过影响交易者预期而稳定汇率；不必消耗资产，反而形成收入。因此，可以达到维持汇率稳定，防止过度投机。

Abstract The operability of the simple Tobin tax is not adequate because of the existances of the definitive problems of the tax base and tax rate,the bounds of the taxable exchange range and the income distribution.There are following advantages in the two-stage Tobin tax:It can crack down on speculations effectively without influencing the capital flow;It can stabilize the exchange rate with influencing exchangers;It can form incomings without consuming assets.Therefore,the purposes of stabilizing the exchange rate,preventing speculations and better steading the financial market can be realized.
