摘　　要：各国出于保护国内企业和遵循国际公约对生产原料贸易的限制,会对涉及这些领域的商品征收进出口关税.对于这种贸易壁垒,税收决策者要以平等互利的双边贸易原则制定使两国社会福利最大化的关税.通过对上游企业只向国内市场销售原料而下游企业可以向双方市场出售成品的模型的研究,判断两国政府应如何对进口商品征税,求出了古诺-纳什均衡下的最优税收表达式.该式表明税收的大小应该随着两国原料成本的单独变化而做相应调整.此外,根据该式推导出的社会福利最优解隐含了促进贸易双方利益的途径,即寻求两国间原料成本具有较大差异的领域进行贸易.Nations charge export and import tariffs in the areas contribute to domestic manu- facturer safeguard and resrictions on production factors according to international agreements. Regarding to these tariff barriers, decision - makers have to maximize social welfare in terms of equality and mutual bemefit bilaterally. The research was done on the model that upriver manufacturer can only sale on the domestic market, however, downriver manufacturer can sale on both domestic and foreign markets. This paper determined Cournot - Nash equilibrium of import tariffs for both countries in this case with best tariff expressions. The expressions im- plied that the tarffs have to be verified with the costs of raw materials of both side independently. Nevertheless, trading on areas with large raw material cost differences between two sides would be the way to a win -win situation.
