  • This study estimates the regional input-output table and GHG emissions in 2019 and then analyzes the economic effects of carbon taxes by region and industry in Korea. The GHG emission, emission coefficient, and emission induction coefficient are estimated to be higher in manufacturing-oriented metropolitan provinces. The GHG emission coefficient in the same industry varies from region to region, which might reflect the standard of product classification, characteristics of production technology, and the regional differences in input structure. If a carbon tax is imposed, production costs are expected to increase and demand and production will decrease, especially in the manufacturing industry, which emits more GFG. On the other hand, the impact of carbon taxes on each region is not expected to vary significantly from region to region, which might be due to the fact that those differences are mitigated by industry-related effects. Since the impact of carbon taxes is expected to spread to the entire region, close cooperation between local governments is necessary in the process of implementing carbon neutrality in the future.

  • Along with the increasing interest in environmental problems such as global warming, the South Korean government has established policies and regulations to reduce the amount of greenhouse gases, targeting a 30% reduction of $CO_2$ compared to business-as-usual levels by 2020. Thus, there have been many studies in construction field to control and reduce the amount of $CO_2$ emitted from buildings. $CO_2$ emission from the building construction could be obtained by using the life cycle assessment(LCA) methodology. In LCA, it is essential to have life cycle inventory(LCI) data of construction materials consisting of $CO_2$ emission data that have been defined and examined in a detailed way in order to obtain more accurate and detailed $CO_2$ emission of buildings. To date, however, the LCI data have been acquired only for the representative materials. Accordingly this study aimed to propose detailed $CO_2$ emission data for steel rebar and H-beam, which are the essential structural steel materials, by strength and type. To accomplish the objective, this study used Input-Output LCA methodology which is based on the Input-Output table. It is believed that the $CO_2$ emission data of steel materials acquired from this study would allow a more accurate assessment of $CO_2$ emission for diverse structural design alternatives.

  • In this study, GNLP(GIS linked non-linear network analysis program) for pipeline system analysis has been developed. This GNLP gets the input data for pipeline analysis from existing GIS(geographic information system) data automatically, and has GUI(graphic user interface) for user. Non-Linear Method was used for hydraulic analysis of pipe network based on Hazen-Williams equation, and Microsoft Access of relational database management system(RDBMS) was used for the framework of database applied program. GNLP system environment program was improved so that a pipe network designer can input information data for hydraulic analysis of pipeline system more easily than that of existing models. Furthermore this model generate output such as pressure and water quantities in the form of a table and a chart, and also produces output data in Excel file. This model is also able to display data effectively for analysed data confirmation and query function which is the core of GIS program.

  • This paper explores the impact of pollution abatement cost on trade balance. First, We derive price pressure of spending pollution abatement cost using I-O table. Then the analysis is extended to the impact on trade balance by manufacturing sectors. The paper explicitly includes indirect effect of pollution abatement cost that is the effect through the change of the other sector prices and excluded in the previous studies. The results show that the impact of pollution abatement cost on trade balance is 0.30~0.46% of total trade volume of Korea. This is lower than that of the United States in 1970's.

  • Development of a train wireless signal control system using LTE-R technology is expected to have a great ripple effect to the existing signal control market. To make inroads into the international market, it is an urgent issue to practicalize the train wireless signal control system. Because it will require a huge budget to commercialize the wireless signal control system, it is necessary to analyze the feasibility beforehand, with a consideration of the domestic and foreign marketability and the impact on related industries. This study investigated the effect of the practicalization of train control system on future railway and national industrial sectors. We suggested the establishment of a framework for economic feasibility analysis, one that can provide criteria for opportunistic valuation. We also verified this framework through case analysis.

  • The purpose of this study is to experiment and simulate the newly-updated Second Generation Model for Korea (SGM-Korea). With the updated model, we tried to simulate effect of carbon tax on $CO_2$ emissions and other macroeconomic variables for Korea. The baseline data are compared with projected profiles by various scenarios to evaluate its performance. Our contribution in this study is to having up-graded the model from its earlier version by building new hybrid input-output table based on 2000 input-output and energy balanced tables. According to our estimation, total $CO_2$ emission in Korea has already increased in 2000 to about 1.86 times the 1990 figure. The level of carbon tax required for the current level of $CO_2$ emission to be reduced to the 1995 or 2000 level seems to be too high for Korean economy to bear. It is possible to find a reasonable level of carbon tax, however, if it can combine it with improvement of energy efficiency at the rate of 0.5% to 1% per year. For Korea to meet its obligation to reduce $CO_2$ emissions, therefore, it is imperative for her to improve energy efficiency as well as to develop alternative energy source reducing its dependence on fossil fuel.

  • Korea is one of the countries that propel new renewable energy industrialization actively in the context of change in this industrial structure. The previous government declared this kind of industrialization as a national goal in 2004 and the current government also supports this strategy. However, it is necessary to check whether this strategy is proper and effective. The reason is because solar, wind and fuel cells that have attracted public attention as the new growth engines cannot replace main industries yet. This paper tries to analyze the economic effects of new renewable energy industrialization by dividing them into production effect and job creation effect. The result of this analysis shows that solar energy is not effective at all, while wind energy is very effective in both production and job creation. In conclusion, this paper suggests that the government has to propel new renewable energy industrialization after consideration of these kinds of economic effects.

  • Greenhouse gas emissions should be precisely forecast to reduce the emissions from industrial production processes. This study calculated the direct and indirect $CO_2$ emission intensities of 401 industries using the Input-Output tables 2003 and statistical data on the amount of energy use. This study had some limitations in drawing study findings because overseas data were used given the lack of domestic data. Other limiting factors included the oil distribution problems in the oil refinery sector, re-review of carbon neutral, and insufficient consideration of waste treatment. Nonetheless, this study is very meaningful since the direct and indirect $CO_2$ emission intensities of 401 industries were calculated. Specifically, this study considered from the zero-waste perspective the effects of waste, which attract interest worldwide since coke gas and gas from the steel industry are obtained as byproducts for the first time in Korea. According to the results of the analysis of $CO_2$ emission intensity per industry, typical industries whose indirect $CO_2$ emission intensity is high include crude steel making, Remicon, steel wire rods & track rail, cast iron, and iron reinforcing rods & bar steel. These industries produce products using the raw materials produced in the industrial sector whose $CO_2$ emission intensity is high. The representative industries whose direct $CO_2$ emission intensity is high include cement, pig iron, lime & plaster products, andcoal-based compounds. These industries extract raw ore from nature and refine them into raw materials that are useful in other industries. The findings in this study can be effectively used for the following case: estimation of target $CO_2$ emission reduction level reflecting each industrial sector's characteristics, calculation of potential emission reduction of each policy to reduce $CO_2$ emissions, identification of a firm's $CO_2$ emission level, and setting of the target level of emission reduction. Moreover, the findings in this study can be utilized widely in fields such as System of integrated Environmental and Economic Accounting(SEEA) and Material Flow Analysis(MFA) as the current topic of research in Korea.

  • 효과적인 물 사용과 물 관리 정책을 수립하기 위해서는 산업적 차원에서의 물 발자국 연구를 통해 산업 전반적인 수자원 활용 상황을 비교 분석할 필요가 있다. 또한 앞으로 국가 차원의 물 안보 정책을 수립하기 위해서는 기후변화와 국제환경 변화로 인해 우리나라의 물발자국 변화를 예측하는 것이 필수적이다. 국외에서는 일찍이 물과 환경전문 교육기관인 UNESCO-IHE를 중심으로 물발자국 산정방식의 이론적 연구와 함께 가상수 무역에 대한 연구를 진행해왔으며, 국제표준화기구(International Organization for Standardization, 이하 ISO)는 2014년 물발자국에 대한 가이드라인을 국제표준으로 지정하였다. 국내에서는 2009년 가상수와 물발자국에 대한 이론이 소개되어 공공기관의 주도로 가상수 및 물발자국과 관련된 연구가 진행되어 왔다. 이러한 연구결과를 바탕으로 데이터베이스를 구축하기도 하였으나 1차 산업 위주로 구성되어 있어 2차, 3차 산업 등 다른 산업에 대한 정보는 부족한 상태이다. 따라서 앞으로는 2차, 3차 산업 등에 대한 연구가 필요하다. 국제 가상수 거래의 도출을 위한 기초자료로서 WIOD의 input-output tables와 environmental accounts 등을 활용하였다. 본 연구에서는 생산량, 물사용량과 관련된 지표를 결합하여 가상수량을 도출하는 과정을 제시하고, 가상수 이동흐름 및 추이를 분석하였다. 이를 위해 주요 16개국(아르헨티나, 호주, 브라질, 캐나다, 중국, 프랑스, 독일, 인도, 일본, 한국, 러시아, 사우디아라비아, 태국, 미국, 베트남)의 농축산물 주요 10개 품목(쌀, 보리, 옥수수, 밀, 콩, 감자, 채소, 소고기, 돼지고기, 계란)을 대상으로 분석을 실시했다. 또한 국가별 가상수 교역량, 국가 간 가상수 교역량에 대한 1989년부터 2014년까지의 데이터셋을 구축하고 이에 대해 분석을 수행하였다. 가상수 교역의 품목별 분석결과 주요 16개국의 주요 가상수 수입 품목은 콩, 옥수수, 밀, 보리 순이며, 주요 가상수 수출 품목은 밀, 콩, 옥수수, 쌀 순으로 파악되었다. 가상수의 종류별로 분석한 결과 가상수 교역량은 지난 25년간 녹색 가상수가 94%의 압도적으로 많은 비중을 차지하고 있었다. 국가별로 가상수 수출입량을 분석한 결과 1989년에서 2013년까지 미국, 브라질, 아르헨티나, 호주 등 주요 농업 국가들이 전 세계 가상수 수출에서 우위를 점하고 있는 것으로 분석되었다.
