CGE모형을 이용한 WTO의 비농산물 시장접근 협상이 자동차 산업에 미치는 영향 분석
고종환 한독경상학회 2006 經商論叢 Vol.24 No.2
This study aims to quantify the potential economic effects of Non-Agricultural Market Access (NAMA) negotiations of the WTO on the economies of major automobile manufacturing countries including Korea as a whole as well as on their automotive industry using a multi-region, multi-sector Computable General Equilibrium (CGE) model with 14 countries/regions and 12 sectors. Three different scenarios of tariff liberalization of NAMA are conducted on the basis of a Swiss formula with coefficient of 10 for all countries (scenario 1), of 15 for all countries (scenario 2) and of 10 for developed countries and 15 for developing countries (scenario 3). Simulation results show that Korea will be one of the winners of tariff liberalization of NAMA in the WTO and that Korean automotive industry will benefit from it to a large extent in terms of its output, domestic sales, exports and trade balance, which implies that Korea needs to actively engage in NAMA negotiations of the WTO.

도시열섬완화를 위한 그린인프라시설의 표면온도 저감 성능평가
고종환,배우빈,박대근,정원경,박윤미,김용길,김상래 응용생태공학회 2018 Ecology and resilient infrastructure Vol.5 No.4
This study is to develop a GSTM(Green infrastructure Surface Temperature Measurment) equipment for measuring the surface temperature reduction of GI by using LID Method. The tests were conducted including GI products such as Greening block, Pervious Block, Soil Block and so on. The GSTM equipment developed by considering the literature surveys are characterized as follows. The non-contact infrared temperature sensor was used to measure the surface temperature, and it was improved to measure the overall average temperature including the center and the corner temperature of the specimen. The developed GSTM equipment was used to compare performance of asphalt and GI products. As a result, the Greening Block show a high difference of 18.4℃ and it contributes to the decrease of surface temperature. 본 연구는 도시의 열섬을 저감하기 위해 그린인프라시설의 표면온도 저감 성능시험 장비를 개발하고, 대표적인 그린인프라시설 제품을 포함하여 실험을 수행하였다. 기존문헌을 고찰하여 장비를 개발하였으며, 개발된 장비의 특징은 다음과 같다. 표면온도의 측정방법은 비접촉식인 적외선온도센서를 활용하였으며, 시편의 중앙 온도만 측정하는 것이 아닌 모서리 부분 온도를 포함하여 전체적인 평균온도를 측정하도록 개선하였다. 개발된 장비(GSTM)를 활용하여 대조군인 아스팔트와 그린인프라시설 제품을 비교하여 성능평가를 수행하였다. 그 결과 식생블록이 18.4 ℃의 높은 차이를 보이며, 표면온도 저감에 기여하는 것으로 나타났다.
Economic Assessment of Korea-EU FTA using a CGE Model with FDI
고종환 한국외국어대학교 EU연구소 2014 EU연구 Vol.- No.36
This paper aims to quantify potential economic effects of the Korea‐EU FTA which became effective on 1 July 2011 using a global computable general equilibrium (CGE) model that explicitly takes into account foreign direct investment (FDI) and foreign commercial presence differentiated by the country of location and ownership. To highlight the importance of FDI and foreign commercial presence, a comparison of the impacts of trade liberalization through tariff elimination and the impacts of liberalization of barriers to FDI and foreign affiliate sales is made. The impacts of liberalization of barriers to FDI and foreign affiliate sales on the Korean economy are predicted to be much bigger than those of trade liberalization through tariff elimination. Major findings of this paper are that Korea’s real GDP and welfare are to increase, as a result of liberalization of barriers to FDI and foreign affiliate sales, by 1.5 to 5.76 times and 1.2 to 2.89 times, respectively, as much as in the case of trade liberalization through tariff elimination. Therefore, it is required to take into account not only the effects of tariff elimination but also the effects of liberalization of barriers to FDI and activities of foreign affiliates for any FTA that Korea pursues so as to prevent an underestimation of its potential economic effects.
