本文利用两国两异质财货的产业内贸易模型,讨论贸易财属性与贸易政策霓争均衡的决定,并获得以下结论:(1)当两国政府均采取相同的进口或出口政策时.不论产品的消费性质,最适进口贸易政策均为课税;最适出口贸易政策将随贸易财的消费性质而定,替代品为出口补贴,互补品为出口课税。(2)当产品为替代品且厂商在两国市场均实行数量竞争的情况下,进口课税政策虽将成为两国政府的优势策略,但出口补贴政策则更具有效率。在产品为互补品且厂商在两国市场均实行价格竞争的情况下,当产品的互补程厦较小(大)时,进口课税(出口课税)政策将成为两国政府的优势策略;当互补程度中等时,两国政府有可能采取差异性的贸易政策。
本文利用兩國兩異質財貨的產業內貿易模型,討論貿易財屬性與貿易政策霓爭均衡的決定,併穫得以下結論:(1)噹兩國政府均採取相同的進口或齣口政策時.不論產品的消費性質,最適進口貿易政策均為課稅;最適齣口貿易政策將隨貿易財的消費性質而定,替代品為齣口補貼,互補品為齣口課稅。(2)噹產品為替代品且廠商在兩國市場均實行數量競爭的情況下,進口課稅政策雖將成為兩國政府的優勢策略,但齣口補貼政策則更具有效率。在產品為互補品且廠商在兩國市場均實行價格競爭的情況下,噹產品的互補程廈較小(大)時,進口課稅(齣口課稅)政策將成為兩國政府的優勢策略;噹互補程度中等時,兩國政府有可能採取差異性的貿易政策。

This paper,an intra-industry trade model with two countries and two heterogeneous goods,is to discuss the attribute of a tradable good and the relevant issues about the competitive equilibrium of trade policy. It resulted in the following inferences: (1)When the governments impose the same import or export policy,their best import policy is taxing the import,whatever attribute the good is ,while their best export policy depends on the attribute of the tradable goods: subsidizing the substitute good but taxing the complementary goods. (2) Given that the goods are substitute goods and these two firms are taking quantity competition strategy in these two countries ,will be the dominant policy for both countries ;the export subsidy ,however ,is comparatively more efficient in this case. Assuming that commodities are complements and two firms are adopting price competition strategy in these two countries ,when the good demand each other to a small extent(to a large extent),taxing import (taxing export)will be the dominant policy for both two countries. As the demand to the complement is merely moderate ,trade policy of discrepancy then is the potential choice for both governments.
