In this paper, I examine the welfare effects of various revenue-neutral tax reforms in the case of two vertically-related oligopolies(downstream and upstream), where the upstream industry is polluting. I show analytically when and how government can improve welfare by initiating various tax reforms, regardless of either the feasibility of a lump sum transfer or the availability of a tax on pollution. The profit wedge that is the difference between the unit price and the unit cost and the marginal environmental damages(MED) becomes important to decidethe direction of a tax reform and is crucial to determine the direction of welfare-improving tax-subsidy schemes. I also show that a tax on pollution(Pigouvian tax) is superior to a tax on intermediate good even in the case of vertically-related oligopolies, because the former always brings in positive welfare effect from the upstream firms' input substitutability, which a tax on intermediate good cannot provide. Some policy implications for 'reducing environmentally-harmful subsidies' are also discussed.

This study analyzes the contribution to the national economy of the stable water supply through managing multi-purpose dam. For the analysis, we consider 17 major multi-purpose dams and build a CGE model with summer water and winter water being the production factors as the base year of 2007. We analyze the economic impact of meeting water demand due to the dam management and estimate the risk premium of reducing the uncertainty of water supply. The analysis results show a significant production decrease in the industries of agriculture, forestry and fisheries and tap water as well as the food and beverage industry using the former industries' output as intermediates in the production and show an production increase largely in steel industry and electronic and electrical industries. Being compared to the benchmark solution, GNP is analyzed as being reduced by 0.22~0.68%. Meanwhile, the risk premium is estimated to be about 4 billion to 24 billion won for the value 01 the measure of relative risk aversion in the range 01 0.5 to 3.0.

This paper investigates the impact of the government R&D expenditure on the IT industry in Korea. The analysis of such impact can be used to derive the policy implications for the IT industry. The contribution of government R&D to the IT industry was analyzed based on the input-output table of the year 1990-1995-2000. The results show that the amount of the government R&D expenditure induced the IT industry to book twice greater production than it would have been in the absence of such government R&D expenditure during the period under investigation. It is also shown that job creation was strongly encouraged in the broadcasting equipment, software and computer-related services. During the period under the study, the composition of the workers in the IT hardware industry remained unchanged while the production increased significantly, which confirms the jobless growth in the IT hardware industry. The results of this study suggest that the government R&D should focus on improving the competitiveness of the intermediate good and parts industry.

This study is to arrange the amount of foreign direct investment(FDI) inflow into the country between 2011 and 2013, using the Input-output Table on the basis of the bench-mark table of the same period, based on the Industry Relation Table. As a result, the average amount of FDI inflow of the three years was estimated 15.3 trillion won, and the average gross product inducement amount 45.8 trillion won. The characteristic of FDI inflow is that it is weighted in the industries with the high index of the sensitivity of dispersion and the high index of the power of dispersion, such as chemical products, electric and electronic equipment and metal products. It is especially anticipated to attract FDI to the industry with the high index of the sensitivity of dispersion used as the intermediary product.

This paper examines whether the TFP growth of the Korean economy slowed down in 2000s based on growth accounting, focusing on how sensitive the results are to the particular aspects of the growth accounting method. There has been no consensus on this issue as the previous studies have provided very diverse results due to the differences in the details of the growth accounting method. Main results of this paper are as follows. First, it is how to calculate the labor income of the self-employed that has the most significant impacts on the estimated TFP growth. Measuring capital stock also matters. Second, the TFP growth of the Korean economy appears to be sustained in 2000s when the extreme assumptions on the labor income of the self-employed are excluded and capital stock is measured by the most frequently-adopted method in the previous studies. For more reliable estimation of the TFP growth, further studies on measuring the labor income of the self-employed are needed.

This study was aimed to derive measures for maximizing ripple effect of construction of overseas industrial complexes on domestic economy. The induced coefficients were estimated for each step of development of industrial complexes by applying the raw data of ICAK and the input-output mode. As a result, for urban service, the fraction of labor costs was high, and for civil engineering, the fraction of profit & loss was high. However, the proportion of intermediate and profit & loss was high in Architecture. Consequently, compare to the same type of overseas constructions, larger effects were seen at urban service in terms of employment, at civil engineering and architecture in terms of business, and at national economy in terms of architecture. These results suggest that in order to maximize ripple effect of construction of overseas industrial complex on domestic economy, it will be needed to seek an order strategy including not only simply sell a land and but also building factories in the industrial complex.

Flammable substances are often present in the raw materials of pharmaceutical products manufactured by pharmaceutical companies. In this case, an excessive amount of flammable substances is added to make an intermediate, and flammable substances that do not participate in the reaction are removed through filtration and drying steps. In addition, the flammable liquid separated in the filtration process is accumulated in the form of splash filling in the filtrate container. In this case, vapor and mist of flammable liquid are generated, which lowers the lower limit of explosion and minimum ignition energy, and increases the risk of fire and explosion due to complex charging. In this study, by analyzing fire accidents that occurred during the recent filtration process of pharmaceutical companies, it is proposed to prevent static electricity accumulation by measures of nitrogen supply facilities, capacity improvement, conductive filter fabric and so on.

The software industry makes it possible to converge science and Information and Communication Technologies (ICT), create new markets, and create jobs. It is a key industry in the 21^st century knowledge and information age, which is growing very rapidly. This study uses Input-output analysis to derive Linkage effect of the software industry in Korea and the United States (US), and compares the result with CO₂ inducement effect to verify whether the industry meets the low carbon emission development strategy. As the result of this study, first, the software industries in Korea and the US are confirmed to have large influences on the national economy. Second, the Korean software industry has a low Forward linkage effect, so it is less affected by the output of other industries. On the other hand, in the US, it has a high Forward linkage effect and can induce a lot of output in others. Third, CO₂ inducement effects of the industry in Korea and the US are both low, confirming that the industry is suitable for a sustainable future.

Purpose: The purpose of this study is to investigate the structural relationship between self-directed learning, online class environment, and learning satisfaction of general high school students. 219 12th grade students in Sejong B High School responded to the survey questionnaire. For data analysis, correlation analysis and structural equation models were implemented. Results are as follows. First, there was a moderate or higher correlation between self-directed learning, online class environment, and learning satisfaction. Second, the model fit of the structural model among variables was good. Self-directed learning had an effect on the online class environment, and the online class environment had a positive effect on learning satisfaction. However, self-directed learning had no statistically significant effect on learning satisfaction. The researcher found the implication that learners' online class satisfaction showed a synergistic effect when students' self-directed learning ability and educators' excellent class environment are created. Also, the researcher proposed to analyze online learning satisfaction by comprehensively considering the individual, family, and school factors of various learners.

현재 지역산업진흥계획이 수립되기까지 수도권 억제와 지역경제 활성화를 위한 다양한 정책 및 법령들이 수립${\sim}$제정되어 왔으나, 그 성과는 미흡하였고, 첨단산업과 지역의 발전을 함께 추구한 과학기술 집적지 조성정책도 연구기관과 산업체간의 기술개발에 대한 수급의 불일치, 지역별 특성화와 차별화 미흡, 사업간 연계성 부족 등으로 성과는 미약하였다. 중앙 부처에서 다양한 지역산업 관련 기술개발 지원사업도 전개해 왔으나, 부처별로 독자적으로 사업을 추진하여, 정책 상호간의 연계성이 부족하고 투자 효율성이 저조하여, 산업자원부에서 산업발전법에 근거하여 2002년 '지역산업진흥계획'을 수립하였다. 이 계획은 지역별 전략산업을 중심으로 한 지역혁신체제 구축에 초점을 두고 있으며, 지역의 내생적 성장을 위한 네트워크 형성, 투입요소 증대에서 지역 산업경쟁력 강화로의 전환, 중앙정부와 지자체의 공동 계획입안 등에서 기존의 정책들과 차이를 보인다. 지역산업정책의 최종목표는 '지역균형발전'이며, 중간목표는 '지역산업의 활성화'라고 할 수 있다. '지역산업의 활성화'를 위한 기본전략으로 '3개 권역별 전략산업 집중 육성'과 '제도적 기반 구축'을 제시하고 있다. 이러한 기본전략은 매우 포괄적이어서 정책수단으로 보기에는 무리가 있다. 따라서 이러한 기본전략 하에 추진하고자하는 사업들을 검토하고 평가의 목적에 맞게 유형화함으로써 동지역균형발전과 지역경쟁력의 강화이며, 그 기본전략으로는 지자체의 역할제고를 바탕으로 한 전략산업 중심의 지역혁신체제(Regional Innovation System : RIS) 구축을 제안하고 있다. 지역 내에서는 각 조직 간의 역할분담이나 연계가 이루어지지 않아 인력과 재원 및 특정분야에 대한 중복투자 문제가 지적되고 있으며 각각 소규모여서 규모의 경제효과를 꾀할 수 없고 경제적 효과가 가시화되는 데에는 오랜 시일이 걸리고 있고, 지역의 산업발전을 체계적으로 기획하고 지역내 다양한 이해관계를 조정하는 총괄 추진기구가 없어 효율적인 지역산업육성에 한계가 있었다. 지방정부의 과학기술예산 및 전담조직, 산업경제예산 및 전담 조직의 부족과 미 정착으로 독자적인 지역과학기술정책이나 지역산업정책은 물론이고 지역혁신정책을 수행하기 어려웠으나, 지역의 특성과 잠재력에 맞는 사업을 발굴하여 중앙정부에 건의하고 지역 내 각 프로젝트를 총괄 조정하는 중개자 역할을 지역전략산업기획단이 그 역할을 수행하고 있다. 지역혁신체제의 중심기관으로 중개기관과 협력 프로그램에 의한 플랫폼 구축 및 지역산업발전의 기획${\sim}$조정기구로서, 선진국의 지역발전기구(Regional Development Agency : RDA)인 지역전략산업기획단이 2002년도부터 산업자원부와 9개 시도에 의해 설립되어 지역네트워크의 활성화와 클러스터의 형성 촉진을 하게 되었고 2004년도에는 13개시도로 확대${\sim}$운영되고 있고, 지역특화사업(H/W)과 지역산업기술개발과제(S/W)와 함께 패케지 형태로 지원되며, 주요역할은 크게 지역산업의 정책기획 분야와 평가관리, 지역혁신역량 조사 및 DB구축 등으로 구분된다. 그중에서도 권역별, 지역별, 지역산업진흥사업 육성과 중장기 산업발전계획을 수립하기 위하여 지역혁신역량을 바탕으로 한 지역 Technology Road Map(TRM)작성사업은 전국공통의 1단계 사업으로 실시 ?榮쨉?, 2005년 3월 기준으로 9개 지역(강원, 대전, 충남, 충북, 경북, 울산, 전남, 전북, 제주) 26개 산업분야를 대상으로 23개가 완료된 상황이다. 이를 근거로 한 지역정책과 R&D 과제 및 필요 인프라의 도출이 체계적으로 구축되어 지역산업 발전을 위한 기술역량이 강화될 것이다.
