Considering the recent substantial increase in national research and development (R&D) budgets in the energy sector there has been increased Interest in the effectiveness of government R&D investments. We conducted a case study to calculate the allowable scale and effectiveness of R&D investment by calculating the direct performance improvement effect resulting from R&D investment as an economic value. Using conditions that existed prior to R&D investments as a reference, five cases in which performance improved due to R&D investments were compared and analyzed. The government's financial investment is increasing rapidly in line with the establishment of the national hydrogen roadmap. R&D is needed to enhance the current low technology readiness level of hydrogen fuel cells compared to solar and wind energy fields. Therefore, an R&D project to improve the performance of the fuel cell system was selected as this case study's subject. Using the results in this study, the allowable level of investment in the task unit of national R&D projects could be calculated. Moreover, it is advisable to provide a standard for rational decision making for new R&D investments since it is possible to determine investment priorities among a large number of candidates.

Under the diagnosis of low employment rate and low growth, the government regards the creation of new jobs through the creative and innovative R&D as an important national plans. This study attempts to measure the employment creation effect of R&D investment of industrial technology by using input-output analysis used in domestic and international broadly. The employment effect can be divided into employment inducement effect and direct employment effect. As a result of the analysis, The employment creation effect of R&D investment of government industrial technology is measured to be 8-12 peoples per 1 billion KRW investment. This results mean that government R&D investment is a effective policy for employment creation. And it is necessary to establish R&D policies that reflect the technical characteristics of the employment creation effect. In short term, it is important that the government invest the superior technology of total employment and direct employment as essential means of employment creation by selection and concentration strategy. In mid-long term, the government should focus on technology spread as technology transfer and opening innovation strategy for employment creation to support superior technology of employment inducement. The results of this study can be used in analysis on the employment creation effect related to industrial technology R&D.

It is not surprising to hear news about irresistible natural disasters all over the world due to climate change. Korean Government has focused on developing a variety of green technologies to reduce green house gasses, in particular, carbon dioxide. This study suggested 18 technology divisions for achieving green highway technology development in six different sub-sectors considering life-cycle of roadway and surveyed 29 highway and/or transportation professionals of three institutes using AHP(Analytical Hierarchy Process) analysis to construct "Green Highway"and realize carbon emission reductions and energy use efficiency in a road sector in Korea. Expert Choice Software was used to rank 18 technology divisions weighted by two-level choices. Transport Operating Infrastructure Improvement, Roadway Policy Implementation, Green Transportation(such as Pedestrian and Bicycle) were highly ranked by respondents according to results of the AHP modeling. Among the 18 divisions, technology policy for supporting R&D investments from development to commercialization was ranked as the most significant one to be focused. Green Transportation Facility Design/Construction/Operation and Eco-Friendly Roadway Plan were followed as expected since professionals have thought that the planning/design step of the life-cycle is a starting point to reduce carbon dioxide from roads more and more. Additionally, comparing the results with the Government investment trend 2006-2011 for the roads, it can be interpreted that the Government should invest to the R&D area more widely than before to promote element and core technology development for Green Highway Construction. Above all, small and mid-sized businesses have to be invested as well as encouraged to undertake green highwayrelated objects to accomplish the divisions which ranked high.

ASPI가 발표한 국가 및 기관별 핵심 기술수준 분석 보고서에 따르면, 44개의 핵심기술 분야 중 대다수에서 중국이 선두를 차지하고 있다. 이러한 결과는 중국이 개방적이지 않은 권위주의 국가로의 글로벌 영향력 이동 가능성을 나타낸다. 본 논문은 '에너지와 환경' 분야의 8개 전략 기술에 초점을 맞추어, 한국의 과학기술 수준 및 핵심 연구자의 현황을 파악하고자 한다. 이를 위해 최근 5년간의 국가 R&D 정보를 수집하고, 과제, 정부투자연구비, 학위별 동향을 분석했다. 그 결과, 글로벌 핵심기술 경쟁에서 한국은 전략기술 분야에서 부족한 부분이 있음을 확인했다. 이러한 분석 정보는 과학기술 혁신 정책 수립과 핵심인재 양성 등에 활용될 것으로 기대된다.

To meet $CO_2$ emission regulation, this study describes the present state of $CO_2$ reduction technology and the effect of the regulation on power industry. In Japan, R&D investment is actively continuing through a long-term R&D project, along with trying to meet the reduction demand by the ways of energy saving and abroad business. EU has made a lot of investments in increasing the efficiency of power generation and developing alternative energy sources. The US is making provision of the portion of reduction by using energy saving program and emission trading, and the current DOE-driven program is addressing the development of cost-effective power systems. In the country, the research to reduce $CO_2$ emission has been mainly driven by the government and research institute supported by the government. Meanwhile, if the reduction obligation imposed on Portugal which is the least strict condition will be enforced in Korea, it is likely that about 50 running power plants should be stopped or shut down after 2015, in spite of voluntary reduction efforts such as conversion to clean fuels, etc. according to the government's long-term electric power need and supply plan.

초기 기술개발주체는 일원적인 기술진보 방향을 따랐으나 R&D 패러다임이 변화함에 따라 고객요구의 중요성을 인식하게 된다. 하지만 3세대 R&D와 같이 고객수요에만 중심을 둘 경우 기술혁신을 꾀하기 힘들어, 현재 보유한 기술개발역량 분석을 바탕으로 시장요구를 이해하고 다른 기술개발주체와 협력할 수 있는 기술투자전략이 요구된다. 광물자원, 에너지자원 기술과 같이 산업경제 및 국민 삶과 직결된, 경제사회 문제해결형 자원기술 개발의 중요성과 필요성은 증대하지만 공적 목표와 기술목표를 결합하는 것이 쉽지 않아 이를 해결할 수 있는 방법론 제시가 필요하다. 즉 효과적인 기술개발 우선순위 및 기술개발 투자전략을 수립하기 위해 기술개발역량 분석뿐만 아니라 정확한 고객수요 분석이 필수적임을 시사한다. 따라서 고객요구 속성을 고려한 사회적 기대 도출방법을 활용하여 3단계 수준의 자원기술 수요를 도출하였으며 수요의 변동성을 고려하여 3년후/5년후의 수요중요도를 측정하였다.

The South Korean government invested about 560 billion won in research and development in the wind power sector over 30 years from 1989 to 2019. In addition, the government has been setting up conditions for the country's wind industry to grow through various policies, including the RPS (Renewable Energy Portfolio Standard). As a result, the size of Korea's wind industry has grown to 1.1 trillion won in annual sales and there are 2,000 people working in the wind energy sector. While the domestic market is weak due to the small size of Korea and there are problems with the NIMBY, the government has continued to support technology developments and support market policies. Despite insufficient performance in overseas markets, the effect of the government is still significant on the growth of the wind industry. In particular, the government's R&D investment program, which focuses on enhancing companies' competitiveness, has spurred job creation in the wind industry and a stable research environment for researchers. In this study, we compared the differences between methods of investigating employment statistics in Korea and those of other countries. We also proposed effective investment measures for the government by analyzing the investment effects according to value chain and types of organization.
