Purpose - This study, in seeking to understand the trade structure of both Korea and China, aims to strengthen Korea-China economic cooperation; it examines trade impediments by analyzing the problems affecting trade and addressing these problems, thereby discovering ways to expand trade between these countries. Research Design, Data, and Methodology - The index of trade intensity developed by the trade intensity theory (Kruger, 1997) is used to analyze the trade decision factors of both countries. Although specific factors should have materialized from the analysis of trade decision factors, determining concrete explanations is difficult in reality, as there are many unsolved and diverse factors. Results - First, the index of A value/B value is the index of Korean versus Chinese market share/Korean versus world market share, which is a measure of comparative market intensity. Second, Korea has a comparative advantage in export specialization and, conversely, China has a comparative advantage in import specialization. Third, compared to 2000, the revealed comparative advantage (RCA) indexes are considerably improved. Conclusions - This study used quantitative measurement for analysis, applying trade intensity theory, trade specialization, and RCA indexes to gauge how inter-trade relations have changed between Korea and China during the past 10 years (2000, 2005, and 2012).

Purpose - This study discusses the effects of human capital in the formation of GVC linkages. We also investigate GVC intensity between Korea and ASEAN. Design/methodology - To solve the doubling-counting problem in evaluating comparative advantage, RCA has been re-computed using domestic value-added (henceforth RCA_VA) at the country-sector level instead of value of trade. The impact of human capital on GVC intensity was empirically analyzed by establishing a panel data set with four industries (ISIC Rev. 4) in eight ASEAN countries from 2005 to 2015 from OECD-TiVA and WDI. Findings - The empirical results show that human capital has a negative effect on GVC intensity in the agriculture and manufacture industries, while it has a positive effect in the service and information industries. The results do not mean that low human capital is a barrier and inefficient to GVC linkages. Low Value-added activities may be more profitable to some emerging countries. These findings suggest that it is important to accurately identify the competitive elements to increase gains from trade under the GVC. Also, it shows that comparative advantages can be misled by an RCA index evaluated in trade volume under the GVC. Originality/value - This study highlights the importance of human capital as a factor for the efficient formation of Global Value Chain (GVC). This study has different from the literature in analyzing the role of human capital in formation of linkage of the GVC. And we clarify the changing patterns of trade by removing the double-counting problem under the GVC.

본 논문에서는 통신 채널에서 발생되는 부호간 간섭의 영향을 최소화하기 위하여 사용되는CCA 적응 등화 알고리즘에서 compact slice 가중치에 따른 성능을 비교하였다. CCA 알고리즘은 기존의 결정 지향 알고리즘 (DDA : Decision Directed Algorithm)과 축소 신호점 알고리즘 (RCA : Reduced Constellation Algorithm)의 결합 방식으로 송신 신호의 constant modulus와 결정 장치의 출력 신호를 compact slice 가중치만큼 고려하여 초기의 수렴 특성 및 정상 상태에서 misadjustment에 의한 등화 잡음을 개선시킬 수 있다. 이 과정에서 compact slice 가중치가 적응 등화 알고리즘의 성능에 미치는 영향을 컴퓨터 시뮬레이션을 통해 확인하며, 성능 지수로는 등화기 출력 신호 성상도, 수렴 특성을 나타내는 잔류 isi, 최대 찌그러짐, MSE 및 채널의 신호대 잡음비에 따른 SER을 사용하였다. 시뮬레이션 결과 가중치가 클수록 모든 성능 지수에서 우월하였고, 특히 SER 성능에서는 신호대 잡음비가 적으면 가중치가 적을때가 우월하였고 신호대 잡음비가 클수록 가중치가 클때가 우월함을 알 수 있었다.

This study examined the comparative advantage of manmade textile (MMT) industries in the United States (US) and South Korea (SK). The Revealed Comparative Advantage (RCA) framework was used to assess the MMT industries' performance in both countries from 2004 to 2013. With the recent ratification of the United States-South Korea Free Trade Agreement (KORUS FTA), it is important to understand the current state of these industries. Using UN Comtrade export data, the RCA index values were calculated and analyzed for 27 MMT commodities, three aggregate groups, and the whole industry. It was found that SK had a consistent comparative advantage for the whole industry. Furthermore, SK had a larger number of products with a comparative advantage. The research findings indicate that the MMT industry in SK is likely to outperform the US following the complete ratification of the KORUS FTA.

The climate change has become one of the most important global issues that require global responses. As one of the leading contributions to climate change, greenhouse gas emissions and Ballast Water Management have attracted growing attention from the international community. The International Maritime Organization (IMO) received its mandate to regulate International Convention for the Control and Management of Ships' Ballast Water and Sediments in 2004. The convention requires that every vessel must be equipped Ballast Water Management System (BWMS) in 2017. Based on this situation, this study aims to analyze the present state and data from the exports of BWMS(HS842121). The results show that as the most leading country in the field, Germany has the largest market share (14.33%), Revealed Comparative Advantage (RCA) index 1.76, and Trade Specialization Index (TSI) 0.636 in the world. The two other leading countries such as Denmark and Netherlands follows the ability of Germany. The Korean market share of HS842121 shows market share (5.98%) which is a bit bellow high compared to other countries. However the RCA index (1.85) presents the state of comparative advantage. In addition, Korea's TSI index (0.453) indicates that it is in the state of export specialization. The Korean BWMS and Shipbuilding industry maintain the state of export specialization. They are also in the state of import specialty. For Korea to raise its export competitiveness and to ensure shipbuilding competitiveness, it is necessary to intensify supporting systems and related policies.

최근 몇 년간 미국의 일련의 보호무역주의 조치와 브렉시트(Brexit) 등 반세계화 행태로 세계의 자유무역체제가 큰 타격을 받았다. 이러한 배경에서 세계 최대 무역 협정인 RCEP가 2021년 11월 15일에 공식 서명되었다. RCEP는 한중일 자유무역지대 구축을 위한 좋은 작업 기반을 제공했다. 첫째, 본고는 한중일 무역협력 현황과 3국 통신 산업의 현황을 기술한다. 둘째, 본 논문은 제8판 GTAP 데이터베이스를 이용하여 자유무역지역 설정 이후 관세가 각각 0%, 5%, 10%로 인하될 때 중국, 일본, 한국의 경제 전반의 변화를 시뮬레이션하였다. 그런 다음 시뮬레이션된 데이터 변경 사항을 사용하고 2019년 데이터를 벤치마크로 사용하여 3개 세율에 따른 3개국 통신 산업의 RCA 지수의 변경 사항을 계산했다. 결국 한중일 자유무역지대가 수립되면 3국의 경제는 다방면에서 서로 다른 수준으로 성장할 것이라는 결론이 나온다. 일본의 통신 산업은 큰 영향을 받지 않을 것이며 한국은 높은 세율로 크게 성장할 것이고 중국은 낮은 세율로 크게 성장할 것이다.
