A two-part model is estimated to see if increasing returns and comparative advantage are empirically equivalent in explaining intra-industry trade. The model has separate mechanisms for determining the occurrence and the extent of intra-industry trade. Estimation is based on an augmented Grubel-Lloyd index derived from the data set on SITC 7 goods at the 3-digit SITC (Revision 4) for country pairs in which Korea is fixed as a source country. Estimation results show that both increasing returns and comparative advantage can explain the occurrence and the extent of intra-industry trade.

Purpose - The purpose of this paper is to analyze the trade structure and competitiveness of China's information technology (IT) industry in comparison to that of Korea and the United States, particularly in terms of quality. Design/methodology/approach - Indices such as trade specialization index (TSI), Revealed Comparative Advantage (RCA), and Market Comparative Advantage (MCA) are used. Further, an Intra-industry Trade (IIT) index is used to analyze qualitative changes in horizontal intra-industry trade and intra-industry trade of high- and low-quality goods. Findings - China's IT industry has a comparative competitive advantage over that of Korea and the United States, and mainly exports goods of inferior quality and imports goods of superior quality. Further, China's horizontal intra-industry trade has been decreasing, while its vertical intra-industry trade has been increasing and vertical trade of inferior quality goods outweighs that of superior quality goods. This shows that China is rapidly catching up with Korea and the United States, even though its qualitative competitiveness has not significantly improved. Research limitations/implication - This study has academic and political implications, as it analyzes changes in China's IT trade competitiveness. However, it is somewhat limited as factors determining qualitative aspects has not been considered. Originality/value - Most studies aggregate analyses of export competitiveness using methodologies such as TSI, RCA, and market share. However, the focus of these methods is price competitiveness. Hence, an examination of the objective and qualitative trade competitiveness of China's IT industry is necessary. this study the trade structure and quantitative competitiveness of the industry by analyzing intra-industry trade focusing on the quality of competitiveness. Therefore, the changes in China's IT industry in the USA and Korea and in foreign trade competitiveness and quality competitiveness are clarified. The results show that the academic and policy implications of these changes in the IT industry will be a useful resource. This is the first study in Korea to attempt such an analysis. This is the first study in Korea to attempt such an analysis.

Intra-industry trade (IIT) has played an important role in international trade of Vietnam as a result of rapid growth of the country. This article investigates the level of IIT between Vietnam and 11 trading partners in Trans-Pacific Partnership (TPP) over the period 2000-2014. Although there have been a large number of empirical researches contributed to the determinants of IIT, most of them only pay attention on developed countries where the trade flows are similar due to similar demand structure and production technology. Until now, there is no study on intra-industry trade between Vietnam and countries in TPP that Vietnam recently signed a trade agreement in early 2016. IIT is measured by the Grubel-Lloyd index. The index shows that the extent of intra-industry trade between Vietnam and the trading countries is not high due to the level of economic development and the market size. The determinants of IIT are examined using a panel regression model. In the empirical analysis, the results indicate that Vietnam's intra-industry trade is positively correlated with country size, while it is negatively correlated with income dissimilarity, the trade openness, and geographical distance. This study contributes to the new theoretical trade theory on the evidence of developing country's IIT.

Purpose - This study aims to examine the dynamic relationship between the variables impacted by the Regional Comprehensive Economic Partnership (RCEP) and the level of intra-industry trade among member states, with the ultimate objective of deducing the short- and long-term effects of RCEP on trade. Design/methodology - This study focuses on tariffs, GDP growth rates, and the proportion of regional FDI to total FDI as research variables, and employs a panel vector autoregression model and GMM-style estimator to investigate the dynamic relationship between RCEP and intra-industry trade among member countries. Findings - The study finds that the level of intra-industry trade between member states is positively impacted by both tariffs and intra-regional FDI. The impulse response graph shows that tariffs and FDI within the region can promote intra-industry trade among member countries, with a quick response. However, the contribution rates of tariffs and intra-regional FDI are not particularly high at approximately 1.5% and 1.4%, respectively. In contrast, the contribution rate of GDP growth can reach around 8.5%. This implies that the influence of economic growth rate on intra-regional trade in industries is not only long-term but also more powerful than that of tariffs and intra-regional FDI. Originality/value - The originality of this study lies in providing a new approach to investigating the potential impact of RCEP while avoiding the limitations associated with the GTAP model. Additionally, this study addresses existing gaps within the research, further contributing to the research merit of the study.

Nowadays, economic growth of China has become an important issue. Due to the demographic position and the market size, China-Korea trade relationship has grown tremendously and significantly. The Chinese relationship with the Korean industry has considerably increased over the years. Various trade competitiveness indices such as TSI, MRCAI, and IITI have been applied to measure the competitive advantage and the complementary of market structure between these two countries. For this purpose, the dataset from the year 2000 to 2008 provided by KITA were used. The MRCAI result show that Korea has specialized in the product of semiconductor, communication equipment, precision machine, automobile, and nonferrous metal. The intra-industry trade level of Korean manufacturing industry is rising in line with the dominance of vertical intra-industry trade(VIIT) trend.

본 연구는 광주와 주요 교역대상국인 미국, 일본, 중국 간 산업내무역을 분석하였다. 산업내무역 분석은 먼저 수평적 산업내무역과 수직적 산업내무역으로 나누고 다시 수직적 산업내무역 중에서 임계치를 0.25로 선정하여 저품질 수직적 산업내무역과 고품질 수직적 산업내무역을 하는 제품으로 나누어 살펴보았다. 광주는 중국과 저품질 수직적 산업내무역을 하는 제품이 거의 없으며 일부 품목에서는 수평적 산업내무역을 하고 있는 것으로 나타나 광주가 중국에 고품질의 제품을 많이 수출하고 저품질 제품을 수입하고 있다는 것을 알 수 있다. 반면 일본 또는 미국과는 주로 저품질 산업내무역을 하고 있어 저품질 제품을 수출하고 고품질 제품을 수입하고 있는 것으로 나타났다. 하지만 중국과는 다르게 고품질 수직적 산업내무역도 하고 있는 것으로 나타났다. 이러한 분석결과에 따라, 수출마케팅 방안으로는 고부가치형 수출체제로의 전환, 성숙단계별 차별화 전략, 현지진출 네트워크 구축, 지역 내 중소기업의 네트워크 구축, 무역전시회에 대한 정부의 지원, 지방 중소기업에 대한 특화 프로그램을 제시하였다.

The objective of this study is to examine Korean fisheries' globalization level. For that, this paper discusses structural changes of world fisheries and level of korean fisheries' globalization. Fisheries' globalization is measured by comparison of IIT(intra-industry trade) and LIT(level of international trade) on eleven countries(Netherland, UK., USA, France, Japan, Spain, Korea, Taiwan, Thailand, Indonesia, Philipinnes). And analysis data are obtained from UN-UNCTAD PC-TAS and FAO Fishstat. As a result of measure of fisheries' globalization, Netherland is the most globalization country of eleven countries. And the next order is Spain, UK, France, Thailand, Taiwan etc. We can classify these countries into four types. Type I is 'International linkage and integration global indutstry' inculding Netherland, UK, Spain, France. Type II is 'Interantional integration global industry' including Taiwan and S. korea. Type III is 'international linkage global industry' including none of eleven countries. Finally, type IV is 'domestic demand and self-sufficient industry'including Thailand, USA, Japan. So we can name the type of korean fisheries' globalization as 'interantional integration global industry'. Usually this type is evaluated that level of international trade is not high but level of intra-industry trade is high. As a result, from now, we should consider policy directions of korean fisheries whether to decide one of four types or not.
