Currently Welfare is emphasized and the trend of SOC investment shows downwards slopping. The pattern of SOC investment also changes focusing on railroad as environmental issues are critical. This study analyzes and compares the effects of sectoral SOC investments based on Input-Output Tables published by BOK (Bank of Korea). The production inducement, value-added inducement, and employment inducement effects of each sector SOC, which consist of road, railroad, port, and airport, are investigated. First, in view production inducement, sectoral SOC investments have stronger economic effects than manufacture sector. The investment of port and road show the highest value-added inducement in construction process. The investment of road records the highest employment inducement in construction and operation process. The empirical ananlysis of regional economic effects, using Regional Input-Output Tables, supports these explanation showing almost same results. As synthesizing these results, the SOC stocks have to be invested consistently for long periods. Especially the road investment is inevitable for employment. Which sector of SOC is invested depends on circumstances. If government emphasizes production inducement, railroad is invested. If focuses on value-added inducement, port.

Korean Shipbuilding industry takes 33.1% of world market. This shows that Korea is number 1 in shipbuilding. Also, this means the shipbuilding industry plays a significant role in national economic development. This Study attempts to analyse the national economic impacts of shipbuilding industry using an inter-industry analysis. The study investigates demand-driven model and the Leontief price model. Specifically, this study investigates production-inducing effect, value added-inducing effect and employ-inducing effect. Also, we estimate the sectoral price effect. The result of this analyses are presented: 0.7891 won in production-inducing effect, 0.3742 won in value added-inducing effect. When 1 won is produced by shipbuilding industry, 3.7808 persons in employ-inducing effect when 1 billion won is produced, and sectoral price effect is 0.0009% due to the 10% increase of price.

The purpose of this study is to analyze the economic effect of the use of recycled aggregate on the construction industry and the effect of increasing the value of the recycled aggregate production industry on the premise of supporting quality assurance technology to promote the high-quality use of recycled aggregate. Accordingly, the production cost of ready-mixed concrete that can be obtained through the use of high-quality recycled aggregate is analyzed according to the recycled aggregate application rate recommended in the recycled aggregate quality standard, The economic effect of general ready-mixed concrete and recycled aggregate-applied rea dy-mixed concrete industry wa s a na lyzed by identifying the domestic rea dy-mixed concrete industry sca le a nd the ra te of satisfaction of recycled aggregate volume, and a cost-benefit analysis method was used to examine the benefits of high-quality recycled aggregate production and sales. As a result, the production cost of ready-mixed concrete is reduced by 2.3~16.2% depending on the application rate, the economic effect of the use of recycled aggregate on the construction industry is about 106.8~142.6 billion KRW, and the effect of increasing the value of the recycled aggregate production industry generated about 1.22 times the benefit.

In order to enhance national science technology and to secure the origin of creative wealth, there is a need to offer accurate and high quality information with semantic technology. Semantic technology enables to significantly unify information and obtain the wanted information in an easier way. Also Semantic technology is a key technology of the next generation having great ripple effect on the whole of IT. In this paper, We analyze an economic ripple effects in terms of production inducement effect, added value inducement effect, import inducement effect, labor inducement effect of Semantic technology using an input-out analysis of the bank of Korea(2009). We also examine an economic propriety of Semantic technology.

본(本) 연구에서는 에너지절약을 위한 주요 정책수단(政策手段)인 저리융자나 세제감면 또는 특별감가상각 인정 등 에너지절약 비용측면의 금융 세제지원이라는 과인성(課引性)정책과, 에너지수요조절를 위한 에너지가격 규제해제(energy price deregulation)나 에너지세(稅)의 추가부과 등 가격관리(조세) 정책의 경제적 효과를 비교 분석하였다. 그리고 에너지세(稅)부과의 경우 과세단계별 효과분석을 통하여 바람직한 과세포인트를 선택하고, 이를 통하여 현행 에너지절약 지원(支援)정책이나 에너지가격 및 조세체계에 대한 개선방향을 모색하였다. 분석결과, 약간의 물가상승 압박효과를 감수하더라도 에너지가격통제 해제나 에너지세 부과가 금융 세제지원제도에 비하여 에너지절약에 있어 그 효과가 크게 나타났다. 또한 에너지과세의 경우 그 대상과 실행시기에 대해서도 신축성을 기하는 것이 바람직한 것으로 나타나 에너지의 소비감소라는 효율성 측면과 함께 수반되는 물가압박요인을 고려하여 신중히 결정되어야 할 것으로 보인다. 그렇지만 단기적으로 에너지가격의 상승을 감수하더라도 DSM 프로그램비용을 자본화해 나감으로써 점진적으로 가격상승요인을 흡수하고 효과적인 에너지소비의 절약을 통하여 국민경제의 에너지비용을 줄여나갈 수 있는 종합적인 에너지대책이 마련되어야 할 것이다.

This paper analyzes quantitative economic effect of accuracy improvement in location based services. This analysis is motivated from the situation that Korea Communications Commission is preparing the notification for 'location accuracy standard.' The analysis includes three level of impacts. Firm level analyzes the impact on revenue of firms. Social level additionally includes consumers' surplus in LBS industry. Lastly, economywide level includes ripple effects to another industries, which uses input-output analysis. The result of analysis shows that the economic value reaches to considerable amount and cost-benefit ratio is considerably high. The consumers' surplus is much larger than revenue increase. This result supports the intuition that many of location based services are for public interest and that the services have much externalities among firms and consumers. This means that the role of government is very important in the execution of accuracy improvement.

The safety and health ledger system, which gives the responsibility of safety and health management for construction site workers to the construction project owner, was introduced as part of the overall revision of the Occupational Safety and Health Act. There is a need to explain the system's effectiveness in terms of economic feasibility to solve the execution problem of the system caused by low awareness and implementation rate. In this study, the economic effect of implementing the safety and health ledger system was analyzed using cost-benefit analysis based on the data discussed at the time of the introduction of the system. Results show that creating and managing the design safety and health ledger caused additional costs in implementing the system. As a result of comparing the cost of preparation and the direct and indirect benefits caused by the reduction of industrial accidents, the benefits were evaluated higher than the costs. Thus, it is thought that the safety and health ledger system reduces construction work accidents and generates economic effects.
