본 연구는 한국과 주요 교역국(미국, 중국 그리고 일본)의 제조업 부문에서의 무역구조의 변화 및 결정요인을 분석하고 있다. 분석기간인 2002-2007년 동안 수출의 집중도는 중국이 가장 높았고 일본, 한국 그리고 미국의 순으로 나타났다. 한국의 수출구조 변화는 미국, 중국 그리고 일본에 비해 빠르게 변화한 반면, 일본의 수출구조는 가장 안정적이었다. 한국은 중국과 요소부존비율의 차이로 인해 상호 간의 수출구조가 서로 다르게 나타났다. 따라서 상호 간의 수출확대를 위해서는 비유사성을 활용할 필요가 있다. 한국과 미일 두 나라, 특히 일본과는 요소부존비율의 유사성 때문에 무역구조가 매우 비슷한 것으로 나타났다. 이로 인해 세계시장에서 일본제품과의 경쟁이 심화되고 있다. 분석기간 동안 한국의 수출제품은 단순노동집약적인 그리고 R&D 집약적인 제품에 비교우위가 있는 것으로 나타났다. 미국과 일본의 경우는 R&D 집약적인 제품, 그리고 중국의 경우는 단순노동집약적인 제품에 비교우위가 있었으며 R&D 집약적인 제품에는 비교열위가 있는 것으로 분석되었다.It was found that export products of China are the most concentrated for the period of 2002-2007. This concentration of Chinese export products is followed by Japan, Korea, and the USA in that order. Since this kind of high concentration of export products are not desirable, it should be diversified to avoid any potential economic loss associated with unfavorable trade-environmental changes against these concentrated export products.
Export patterns of Korea changed faster than those of the USA, China, and Japan for the period of 2002-2007. On the other hand, export patterns of Japan remained the most stable in the same period. Therefore both Korea and UJC (i.e., the USA, Japan, and China in short hereafter) should fully adjust their economies to ever-changing patterns of their exports.
It was found that Korea’s export patterns do not resemble those of China due to the differences in factor endowment ratios of China and Korea. Therefore Korea can increase her exports to China by exploiting non-similarity of Korean and Chinese export patterns.
Both UJ (i.e., the USA and Japan in short hereafter) and Korea had similar export patterns due to the resemblances in factor endowment ratios of UJ and Korea. Especially, Korean export patterns became increasingly similar to Japanese export patterns and Korean products’ competition with Japanese products in the world export market became increasingly severe. Therefore both UJ and Korea should cooperate in exporting their products in the world market.
It was found that Korea exported products which are less skilled human capital intensive and more R&D intensive for the entire period of 2002-2007. Therefore Korea should try to export more of these products to the world market from now on. The USA is found to have exported products which are more R&D intensive for the entire period of 2002-2007. Therefore the USA should try to export more of these products to the world market from now on.
It was found that Japan exported products which are more R&D intensive for the entire period of 2002-2007. Therefore Japan should try to export more of these products to the world market from now on. China is found to have exported products which are less skilled human capital intensive and less R&D intensive for the entire period of 2002-2007. Therefore China should try to export more of these products to the world market from now on.
