Northeast Asian Economic Cooperation and Strategy for the Business and Financial Hub in Korea

Young-Man Yoon(윤용만),Taek-Dong Yeo(여택동) 한국경제통상학회 2006 경제연구 Vol.24 No.3

  As the most rapidly growing region in the world, Northeast Asia has been drawing increasing attention from the international community nowadays. In spite of impressive economic growth and development, the Northeast Asian pillar of the world economy is relatively weak, beset with many challenges. Therefore, there is much to be done multilaterally as well as bilaterally in the efforts to improve regional economic cooperation. Virtually, the three countries can and will make economic cooperation on the various issues.<BR>  The rapid economic growth in the Northeast Asian region has recently gained momentum in establishing business and logistics hub within Korea. Evidently, Korea can be a possible candidate for business hub in the Northeast Asian region. In addition, the recent development of economic cooperation in Northeast Asia has given rise to the need for huge volumes of investment funds. This has, in turn, increased the need for the development of a financial center to serve as a conduit to facilitate the capital inflow into the region.<BR>  The objectives of the present paper briefly describe economic relations and cooperation among China, Japan, and Korea in the Northeast Asia and then discuss the strategies for realizing business and financial hub in Korea. First of all, this paper studies the features of trade and foreign investment among the three countries and the recent development of economic cooperation in Northeast Asia. Finally, this paper investigates the necessary tasks and strategies for the realization of business and financial hub within Korea in Northeast Asia.   최근 동북아 지역이 국제사회로부터 많은 주목을 받고 있다. 그러나, 지난 30 여년 동안의 분부신 경제성장과 개발에도 불구하고 글로벌경제가 동북아지역이 차지하는 비중은 아직 상대적으로 미약하고 수많은 문제와 도전에 직면하고 있다. 따라서 동북아의 지역경제협력을 증진시키기 위하여 양자간 또는 다자 차원에서 해야 할 일이 많다. 실제로 동북아 3국은 여러가지 분야에서 협력할 수 있고 협력할 것이다.<BR>  동북아지역의 급속한 경제성장에 따라 최근 한국 내에 비즈니스 및 물류허브를 구축해야 한다는 논리가 설득력을 얻고 있다. 명백히 한국은 동북아지역의 비즈니스허브의 좋은 후보지가 될 수 있을 것이다. 한국 정부도 동북아 비즈니스허브(중심)로 발돋움 하기 위하여 인천, 부산, 광양지역에 경제자유구역을 지정하고 고부가가치 서비스 및 R&D산업을 유치하기 위하여 노력하고 있다. 또한 부산과 광양항만을 경쟁력있는 양항체제로 육성하고 인천공항을 동북아 허브공항으로 변환하는 노력을 지속적으로 경주하고 있다. 그리고 최근 동북아지역의 경제협력의 진전은 엄청난 투자자금을 요구하고 있다. 결국 이것은 자본흐름을 동북아지역 내로 유치하기 위하여 국제금융센터의 발전을 필요로 한다.<BR>  본 논문에서는 동북아 3국의 무역투자 측면의 경제관계를 간단히 살펴보고, 지역경제협력 현황 및 전망을 논의한 이후, 한국 내에 동북아 비즈니스-금융허브를 실현하기 위해 필요한 과제와 전략을 구체적으로 연구하고자 한다.

This study was conducted to analyze seasonal variations of de-icing salt ions harvested from soils and plants according to salt damage of Pinus densiflora f. multicaulis, a evergreen conifer, on roadsides. Pinus densiflora f. multicaulis was divided into three groups referred to SD, ND, and WD (serious salt damage (SD) = 71-100%, normal salt damage (ND) = 31-70%, and weak salt damage (WD) = 0-30%) based on the degree of visible foliage damage, and measured acidity (pH), electrical conductivity(EC), and de-icing salt ions (K⁺, Ca²⁺, Na⁺, and Mg²⁺) harvested from soils and plants. The results indicated that acidity, electrical conductivity, and de-icing salt ions of soils and plants were significantly affected by seasonal variation and salt damage. In addition, a strong positive liner relationship was observed in plants between the concentration of de-icing salts and salt damage in spring, while the relationship among seasonal variation and salt damage in soil were not significant. The results from this study has important implications for the management of conifer species in relation to salinity and roadsides maintenance.

Tropaeolum majus, with a high decorative and food demand for vertical greening systems, has been utilized to revitalize urban agriculture. The effects of number of non-woven fabrics in a non-water environment and the adaptability of T. majus to this system were investigated. Planting ground composition of the container-type wall vertical greening system was made using non-woven fabric in one, two, three, or four layers. The results showed that the soil water content remained the highest when the non-woven fabric comprised 4 sheets. The morphological properties showed more growth with the 4 sheets than with 1, 2, and 3 sheets. In terms of physiological characteristics, chlorophyll content was mostly high in the 4 sheets, while shoot fresh weight value was in the order of 3 > 4 > 2 > 1 sheet, and root fresh weight value was in the order of 4 > 2 > 1 > 3 sheets. The dry weight of the measured values in the shoot was in the order of 4 > 3 > 2 > 1 sheet while no clear difference was found in the root of each treatment. The difference in the flowring characteristics was not different, but in evaluating the characteristics as a whole, the growth in the three layers of non-waven fabric was the best. In addition, the soil moisture contents and the growth characteristics were statistically significant as a positive correlation between the groups. Thus, greater the non-woven fabric, the higher is the adaptability of T. majus to dry stress under soil water-free conditions by maintaining soil moisture content. This showed that it represented an effective alternative as a method of vertical greening system for lower maintenance urban agriculture.

미국 양적완화 축소와 우리나라의 외화조달 유동성리스크에 관한 연구

김성철(Kim, Seoung Chull),윤용만(Yoon, Young Man) 한국경제통상학회 2015 경제연구 Vol.33 No.3

본 연구는 2014년 이후 시행된 미국의 양적완화 축소조치가 우리나라의 외화 유동성 리스크에 어느 정도 영향을 미치는 지를 파악하는 데 있다. 이를 위해 우리나라 및 미국의 일별(daily) 금융시계열자료를 이용하여 우리나라의 외화조달 위험지표(Foreign Currency Funding Liquidity Risk Index)와 미국의 통화정책금융지표(Monetary Policy Financial Index)를 비교분석하였다. 지표 산정을 위해 우리나라는 2004년 10월부터 2013년말까지 5년물 국가 신용파산스왑(CDS. Credit Default Swap) 프리미엄과 1년물 원달러 스왑베이시스(Swap Basis)의 일별 시계열자료를 활용하 고 미국은 양적완화통화정책이 축소될 경우 영향받을 것으로 예상되는 5가지 금융지표 - 미연 준실효이자율(Federal Fund Effective Rate), 미연준보유자산(Federal Reserves), TED spread, 5년 물 미국채 수익률과 A등급 금융기관 신용스프레드 및 VIX를 활용하였다. 산정된 지표에 대해 Granger Representation Theorem을 적용한 오차수정모형(Error Correction Model) 을 적용한 결과 두 지표간 공적분회귀 관계가 파악되었다. 두 지표간 장기 공적분 관계형성은, 예를 들어 미연준이 양적완화 축소와 같은 통화금융정책을 시행할 경우 미국 통화정책지표에 포함된 5개 금융지표에 영향을 주고 이는 우리나라의 외화조달시 지불하는 CDS 프리미엄 등 에 영향을 미치고 외화 유동성 상황에 영향을 줄 수 있음을 의미한다. 모형의 적합성 등을 검토하기 위해 태국,인도,멕시코,브라질,남아프리카공화국 등 5개국에 벡터오차수정모형(Vector Error Correction Model)을 적용한 결과 브라질을 제외한 태국 등 4개국은 공적분관계가 파악되며, 이들 국가는 2008년 글로벌 금융위기 이후 GDP 대비 간접투자 비중이 높아지고 동조화되고 있는 양상을 보이고 있다. 충격반응함수(impulse response analysis)를 시도한 결과 우리나라는 외부충격 발생시 충격이 지속될 가능성이 높아 거시건전성 제고, 외환보유고 확충 등 적합한 선제적 정책 노력이 필요하다. The purpose of this study is to find out how much tapering measures taken by the FED since January 2014 could affect the foreign currency liquidity risk of Korea. For this end, two indices, monetary policy financial index of the United States and foreign currency funding liquidity risk index of Korea are developed, using daily time serial data. To be more specific, the index model for the foreign currency funding liquidity risk is set up based on 5 year's CDS premium and 1 year's KRW-USD swap basis. The index model for monetary policy financial index is composed of five daily explanatory variables - Federal Effective Interest Rates, Federal Reserves, TED spread, credit spread between the yields on US 5-year treasury bond and the yields on bonds issued by A rated financial institutions in the US, and VIX. The precedence and the accuracy of those indices developed in this study are analyzed on an econometric basis using a regression analysis model and Error Correction Model known as Granger Representation Theorem. The outcomes of regression result show that co-integration relationship exist between the two indices and that they are able to identify the long-run equilibrium relationship. The meanings of cointegrated indices are that FED'S tapering, which are reducing the purchasing amount of securities including mortgage-backed securities and raising Federal Reserve Interest Rates, could affect the 5 financial variables aforementioned. These would in turn affect the foreign currency funding spread and the level of liquidity risk of Korea. To further study the cointegration relationship between other developing countries, Thailand, India, Mexico, Brazil and South Africa, are applied to VECM model. The results show that all four countries have the cointegraing relationship, except Brazil. It is also examined that these four countries's foreign debt investment share of total GDP is increasing after the global financial crisis. Given the high possibility of sustained external shocks as impulse response analysis shows, preemptive policy efforts such as reinforcement of macroeconomic soundness, expansion of foreign-exchange reserves are needed.

This study aims to identify the most tolerant species under salinity stress from amongst Asteraceae and Poaceae. The seeds of six species were exposed to different concentrations of CaCl₂ (0, 9, 18, 45, 90 mM) and NaCl (0, 17, 34, 85, 170 mM), and germination was measured once every two days. The results indicated that percent germination of the six species of Asteraceae and Poaceae seeds were affected differently by changes in salinity concentration. Seed germination was reduced as salinity levels increase, and longer mean germination times correlated to lower percent germination and earlier germination cessation. Both Asteraceae and Poaceae seeds had the highest germination rates at 18 mM CaCl₂ and 34 mM NaCl, and seed germination and growth were severely reduced at salinities greater than 90 mM CaCl₂ and 170 mM NaCl. In the seeds of Poaceae, salt resistance was strong in the order of Miscanthus sinensis Andersson, Pennisetum alopecuroides (L.) Spreng., and Phragmites communis Trin. In the seeds of Asteraceae, salt resistance was strong in the order of Dendranthema zawadskii var. latilobum (Maxim.) Kitam, Aster yomena (Kitam.) Honda, and Dendranthema boreale (Makino) Ling ex Kitam.. Overall, the germination rate was higher in Asteraceae than in Poaceae. This study demonstrated that Dendranthema zawadskii var. latilobum (Maxim.) Kitam. is the most tolerant species and that a relationship exists between the salt tolerance of percent germination and the mean germination time in the leaves.
