产业内贸易理论评述 产业内贸易理论评述 　　(一)产业内贸易理论的积极意义 产业内贸易理论是对传统贸易理论的批判，其假定更符合实际。如果产业内贸易的利益能够长期存在，说明自由竞争的市场是不存在的。因为其他厂商自由进入这一具有利益的行业将受到限制，因而不属于完全竞争的市场，而是属于不完全竞争的市场。另外，该理论不仅从供给方面进行了论述，而且从需求方面分析和论证了部分国际贸易现象产生的原因以及贸易格局的变化，说明了需求因素和供给因素一样是制约国际贸易的重要因素，这实际上是将李嘉图理论中贸易利益等于国家利益的隐含假设转化为供给者与需求者均可受益的假设。这一理论还认为，规模经济是当代经济重要的内容，它是各国都在追求的利益，而且将规模经济的利益作为产业内贸易利益的来源，这样的分析较为符合实际。此外，这一理论还论证了国际贸易的心理收益，即不同需求偏好的满足，同时又提出了产业间贸易与产业内贸易的概念，揭示了产业的国际分工和产业间国际分工的问题。 The comment on the theory of intra-industry trade (I) the positive significance of the theory of intra-industry trade The theory of intra-industry trade is the criticism on the traditional trade theories, and the assumption is in line with the reality.

Because other manufacturers will be limited to have free access to this profitable industry, so it doesn’t belong to the perfect competition market, but belongs to the imperfect competition market. In addition, this theory not only makes discussion from the supply, but also makes analysis and discussion on the reason for a part of international trade phenomena and the change of trade patterns from the demand, which shows that the supply and demand factors are the important factors to restrict the international trade. Actually, this is the assumption conversion from the implicit assumption of Ricardo’s theory that the trading interest is equal to the national interest to the assumption that supplier and demander can benefit. This theory also considers that the economies of scale are not only the important content of the contemporary economy, but also the interest that each country is pursuing. Moreover, this theory takes the interest of the economies of scale as the source of intra-industry trade interest, such analysis accords with the reality. In addition, this theory also demonstrates the psychological income of the international trade, namely, the satisfaction of diffe
