| Intra-industries trade emerged after world war Ⅱ.Especially since 1960s', Intra-industries trade have lured economists' attentions. Now Intra-industries trade has been 60% of international trade amount. Intra-industries trade is a hot issue among economists. According to David Ricardo's classic theory of comparative advantage and Heckscher and Bertol Ohlin's theory of factor endowment, international trade should occur between who differ considerably in factor endowment , however. Intra-industries trade occurred among industrialized countries similar in factor endowment, and they trade the same or similar goods. The new phenomenon calls for a theoretical explanation. In the new century, economy globalization would be more obvious, the connection between countries would be tighter, international trade would increase at a higher speed. The question that how China better boosts its foreign trade so as to further advance the national economy deserves priority and profound investigation on the part of the international trade media in China. The thesis explores the Intra-industries trade to provide a new thinking of developing international trade, based on domestic and foreign economists' research and connecting with China's situation. So the logic structure of this thesis starts from analyzing Intra-industries trade to provide the theoretical foundation of researching China's Intra-industries trade development. The thesis is divided into four parts.The first part is concerned with some fundamental explanation of intra-industries trade. In order to give a clear and orderly explaining on the reason and interests origination of Intra-industries trade, the thesis put some fundamental conception and brief analysis in the first part, which is subdivided into three parts: 1, the definition of Intra-industries trade and understanding "intra". There are different definition to Intra-industries trade scope, I set forth my own understanding at first. 2, the situation of Intra-industries trade in international trade fields. Intra-industries trade has constituted more than half of the total international trade, so it is necessary to research on intra-industries trade. 3,Here in this section, only a small space is devoted to explaining intra-industrial trade on the ground that some portion of intra-industrial trading occurs under special reasons, which go beyond the focus of the field of endeavor The second part will present the development history of the theory of intra-industrial trade and further analyze it. All theories have their own development history. In my opinion, to search the theory is to search its history. There are three sections:1. The origination and development of intra-industries. After World War II, great changes has taken in the international trade. The stigma of Leontief came out. Traditional international trade theory can't explain it. So modern international trade theory emerged. Another noticeable phenomenon is that a lot of intra-industries exist in the Europe Community. It attracts economists' attention to search the theory of the intra-industrial trade, such as Grubel, Loiyd, etc. 2,the comparison between the main idea of theory of intra-industry trade and classical type. International product divergence, demand preference, and scale economy advantage are three important points of the theory. Product divergence is the element of pushing intra-industrial trade. Demand preference is the guarantee. Scale economics advantage is the interest source. I compare it with the comparative advantage of David Ricardo and factor endowment of Heckscher -Bertol ohlin.3, the interest resource of the intra-industrial trade. The interests of Heckscher - Bertol lies in that through widening the product of closely using rich factors, the price of product drop down, then we can get comparative interests While those countries with same background of factor endowment get their interests through scale economy. The third part comments on the theory type and the theory itself. F... |
