本文研究了产品差异化的垂直相关产业的最优出口政策，分析了产品替代度和市场结构对最优出口政策的影响。结果表明，在同类商品竞争的类似模型中得到的结果不再成立时，商品的差异。事实上，产品可替代性的程度在决定出口政策方面起着重要作用，也决定了一个国家在贸易政策战下与自由贸易相比是否能过得更好。采用差别化的产品设置还可以比较古诺竞争和贝特朗竞争下的出口政策和各国的福利水平。研究发现，比较结果对产品的可替代程度也很敏感。
This paper studies the optimal export policy in the context of a vertically related industry with differentiated products, and analyzes the effects of the degree of product substitutability and market structure on the determination of such a policy. It is shown that the results obtained in a similar model with homogeneous goods rivalry no longer hold when the goods are differentiated. Indeed, the degree of product substitutability plays an important role in the determination of export policies, and also determines whether a country can be better off under a trade policy war compared to free trade. The use of a differentiated product setting also allows one to compare export policies and countries' welfare levels under both Cournot and Bertrand competition. It is found that the results of the comparison are also sensitive to the degree of product substitutability.
