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.

2014년 국토교통부 예산이 전년대비(22조원, 추경포함) 5% 감소한 20.9조원으로 국회 본회의를 통과하였다. 경기활성화 및 일자리 창출을 감안하여 SOC투자 규모가 크게 줄어들지는 않았지만, 향후 복지지출 등의 수요증가로 SOC투자여건은 계속 어려워질 전망이다. 이러한 가운데 편안하고 접근성이 좋은 SOC에 대한 국민들의 기대수준은 더욱 높아지고 있어 국토교통부는 올해 SOC투자 효율성을 제고하는데 초점을 둔다는 방침이다. 즉 도로, 철도 등 주요 SOC사업의 투자 패러다임의 효율성을 높이고, 국민들의 체감효과도 높이는 방향으로 전환해 나갈 계획이다.

최근 건설산업은 공공 및 민간부문의 발주물량 감소가 가시화되고 있으며, 최저가입제에 의한 사업수익율 하락 추세는 향후 건설업 붕괴위기, 건설산업 사양산업화라는 비관적 견해가 떠돌 만큼 건설업 전반이 심각한 위기를 맞고 있다. 정부는 재정 부족으로 인하여 SOC사업의 축소조정이 불가피하지만 국가경제의 악영향 해소와 신속한 경쟁력 회복을 위해 SOC사업에 대한 투자확대와 푹소범위 최소화의 필요성을 인식하고 있으며, 이에 재정부족과 SOC 확충이라는 두가지 문제를 해격하기 위해 민간투자사업이 활성화되고 있는 실정이다. 현재, 정부에 의해 주도되고 있는 민간투자사업의 제도 및 법률의 개정방향은 피간 건설업체가 주도하던 민자사업에 대하여 연기금 및 금융권으로의 전환을 예고하고 있으나, 현실적으로 금융권이 자체적으로 SOC 사업에 대한 투자를 위한 사업 타당성 분석이 어려운 실정이므로 이에 대한 대안으로 SOC 민간투자사업에 대한 노하우를 축적한 건설업체의 SOC 민간투자사업 분야에 아웃소싱 개닐념 도입, 특화하여 효율성을 극대화 시킴으로써 사업의 안정성 확보와 동시에 투자 수익 실현을 통하여 SOC 민간투자 활성화에 견인차 역학을 할 수 있는 전문운영회사의 도입에 대하여 논하고자 한다.

Present private infrastructure investment in SOC investment has increased up to $11\%$ compared to the year 2003 and it is expected to increase in the future. In spite of its rapid increasement we don't have definite standard or system on distinctly presented rate of return for domestic private infrastructure investment yet, and practical and scientific research is not sufficient, compared to its necessity and importance. Hence, in this study we tried to build theories systematically, which are related to rate of return of private infrastructure investment to promote SOC private infrastructure investment to last successfully and present the proper level of rate of return of private infrastructure we investment appropriate in domestic situations through diverse analysis. Therefore, to present reasonable rate of return, we used 5 methods: existing research analysis, case study, financial index analysis, analysis of investors rate of return, and analysis of rate of return in a real estate market. After comparing and analyzing these methods, Ive presented in the end the appropriate level of rate of return of private infrastructure investment, which can be applied in a domestic market.

The purpose of this study is to secure reasonable transportation infrastructure stock for enhancing national competitiveness in Korea. National competitiveness may be defined as a country's overall capacity to create the most effective social structure, institutions and policies that allow her company within the national boundary to be more competitive in the world market. If Korea's transportation infrastructure stock is not sufficient and a connection among transportation facilities is not efficient, we should pay the social and economic cost. As a result, we worry that national competitiveness may drop. Some methods to maintain or to increase the national investment for transportation infrastructure that are suggested from this study are as follows: Firstly, we need to operate the Spcial Account for Traffic Facilities. Secondly, the investment should be focused on the facilities and districts in needs. Thirdly, PFI (private finance initiative) policy should be aimed at investing for the highly economic-valued projects.

This Research suggested direction of development and analyzed necessity and given condition of CM(Construction Management) operation system of SOC private infrastructure project which is judged to grow up continuously from now on, Direction of development which is suggested in this research is largely there, (1)development of SOC private infrastructure project CM work standard process guide, (2)development of SOC Private Investment project feasibility study Performance standard, (3)checklist of SOC by stages and functionally private investment projects risk. Through this development, later we judge effect not only supply of a model case to artivate CM system but heightening of efficiency in domestic construction industry.

프로젝트 파이낸싱은 프로젝트 자체의 사업성과 프로젝트 현금흐름에 근거하여 발생하는 수익을 담보로 사업자금을 차입하고 운영 시 발생하는 수익으로 대출금을 상환하는 재원조달방식이다. 이 금융기법은 주로 광산 및 천연자원개발 사업에서 수 백년동안 이용되어 왔으며, 우리나라의 경우는 대규모 SOC민간투자사업에서 주로 활용하고 있다. 최근 우리나라 SOC민간투자사업에서는 기존에 정부와 민간사업자간에 체결하였던 실시협약 상의 재원조달 구조를 새롭게 변경하거나 유리한 금융기법을 이용하는 사례가 빈번히 나타나고 있다. 본 연구는 우리나라에서 프로젝트 파이낸싱 기법으로 어떻게 SOC민간투자사업에 투자하고 있는 지 분석하고 현황을 파악하였다. 또한 민간투자사업의 자본구조와 Refinancing의 발생사유를 분석하였으며, 광주제2순환도로, 신공항고속도로, 천안논산고속도로 민간투자사업에서 Refinancing 사례도 분석하였다. 그리고, Refinancing에 대한 효과가 어느 정도 인지 측정을 하였다. 결론적으로 Refinancing 효과가 사업에 대한 수익성을 높이는 효과와 부채비율이 높아져 운영위험이 증가하는 것을 실증적으로 보여주었다.

To enhance the competition of National power, the investment of SOC is an essential factor for infrastructure construction. The capital for SOC is so gigantic and the national finance is limited, engagement of various subject is necessary. So, Government is promoting the private sector to invest capital in SOC development. Nevertheless the increasement of SOC investment, various problems were issued in selection & operation of BTL. Therefore, to raise the probability of success for BTL project, escalation, unification and specialization of BTL affairs, BTL selection process were suggested in this study.

Since 1970 transportation investment has been made rapidly, however the doubt on duplication and overinvestment of transportation facility also has been brought up. Thus the necessity for reasonable estimation of investment scale increases. In this paper various researches related to this subject are reviewed and categorized according to their methodologies, namely, the methodology using international comparison, trend of investment policy and endogenous economy development model. Based on these methodologies, AHP is applied to calculate proper investment scale. The result shows that the budget for satisfying the investment scale is estimated about 19.51~24.49 trillion won. This value is 4.28~9.26 trillion won higher than the proper investment budget established in National Fiscal Management Plan. In the future, it is necessary to establish systematic and efficient transportation investment plan by developing transportation policy model which can assess the economic feasibility, social equity and environmental soundness etc. at the same time.

The Korean government is encouraging positively PIP(private infrastructure project) to relieve financial burden and get the facilities in time. The portion of the PIP has grown rapidly into 15% of the whole SOC(Social Overhead Capital) projects. It is estimated that the growth will continue for the present. However, there are still rising problems on efficiency of the project and productivity, properness of the project scale are pointed against surprising growth. In this study, we analyze underlying problems of private infrastructure investment project and suggest CM Models to relieve the problems. To verify the validity of the suggested models, a survey has been conducted through questionnaires and analyzed the taste of the stakeholder. The owner-support Model is chosen as the practical model to apply in time. By applying the suggested model to PIP, it is possible to enhance the efficiency and productivity of the project.
