国际多市场寡头是Bulow( 1 985)提出的多市场寡头概念在国际贸易领域的自然延伸。在本文中 ,市场之间联系的纽带是本国企业具有规模收益递减的生产技术。本文的主要结论是 ,第一 ,如果本国企业与外国企业在外国市场进行价格竞争 ,那么 ,最优干预组合包括国内生产补贴与出口税 ,它们对本国福利的作用是一致的。第二 ,如果本国企业与外国企业在外国市场进行数量竞争 ,那么 ,最优干预政策组合包括国内生产补贴与出口补贴 ,它们作用于本国福利的方向是不一致的 ,这时 ,本国政府用国内生产补贴执行反托拉斯职能 ,用出口补贴执行利润转移职能。第三 ,作为模型的一个应用 ,本文论证了出口退税政策会加剧国内市场的扭曲 ;而且它不一定能够提高本国福利。
The international multi-market oligopoly is a natural extension of the multi-market oligarchy proposed by Bulow (1985) in the field of international trade. In this paper, the bond between the markets is the production technology of domestic enterprises with decreasing returns to scale. The main conclusion of this paper is that firstly, if domestic enterprises compete with foreign enterprises in foreign markets for price competition, then the optimal combination of interventions includes subsidies for domestic production and export taxes, which are consistent with their own welfare. Second, if domestic firms and foreign firms compete in quantity in foreign markets, the optimal combination of intervention policies, including subsidies for domestic production and export subsidies, is inconsistent in the direction of national welfare. In this case, the domestic government uses domestic production Subsidies perform the antitrust functions and use export subsidies to perform the profit transfer functions. Third, as an application of the model, this paper argues that the export tax rebate policy will exacerbate the distortions in the domestic market; and it may not necessarily improve domestic welfare.
