基于差异化产品模型的出口退税政策分析
首发时间:2008-08-04
摘要:通过建立一个国际双寡头模型,本文参考Dixit差异产品需求结构,在一个统一的框架下研究出口退税对于不同差异程度产品的影响。通过分析,发现在数量竞争情况下,不论产品是否有差异,出口退税都会增加本国企业利润并促进本国福利。价格竞争时,如果产品间差异显著,出口退税率上升可以增加本国企业利润、提高本国福利;假如产品同质,出口退税与本国企业利润以及本国福利之间关系不确定,特别的,如果政府对本国企业提供R&D补贴,那么对同质产品的出口应该予以征税。

The export tax rebate policy analysis based on the difference product model
Abstract:Establishing an international duopoly model, using Dixit different product demand structure, this paper examines the impact of export tax rebate on the export products of defferent degree of difference. We found that under cournot competition cases, regardless of whether there is a difference between products, the export tax rebate will increase national corporate profits and promote national welfare. Under Bertrand competition, if significant differences between products, the export tax rebate rate will increase domestic enterprise profits and improve national welfare; while if there are no difference between the products, the relationship between export tax rebate and national corporate profits and national welfare is uncertainty. In particular, when the Government provides R&D subsidies to domestic enterprise, export the same product should be taxed.
