초록

1970년대 이후 급격한 경제성장과 함께 교통SOC 투자 또한 지속적으로 이루어졌으나, 최근 중복 및 과투자 논란에 따른 합리적 투자규모 산정에 대한 필요성이 증가하고 있다. 이에 본 연구에서는 적정 투자규모 산정관련 국내 외 다양한 연구를 검토하고, 국제비교, 국내 SOC 투자재원규모, 내생적 경제성장모형 등 3가지 방법을 통해 투자규모를 산정하였다. 각각의 투자규모 산정방법은 규모의 적정성, 정책성, 경제성 등을 고려하여 산정하였기 때문에 이를 종합할 수 있는 AHP 기법을 활용하여 합리적인 수준의 투자규모를 제시하고자 하였다. AHP분석결과 내생적 경제성장모형의 가중치가 0.4433으로 가장 높게 도출되었으며, 다음으로 국내 SOC 투자재원규모(0.3666), 국제비교(0.1901) 순으로 나타났다. 가중치를 이용하여 산정된 적정 교통 SOC 투자규모는 2019년 기준 19.51조원~24.49조원으로 산정되었으며, 국가재정운용계획대비 약 4.28조원~9.26조원 높게 도출되었다. 이는 경제적 측면의 가중치가 높게 반영되어 투자규모 산정이 이루어졌기 때문인데, 향후 국내 외 여건 및 정책변화에 부응하기 위하여 적절한 투자규모산정 방안이 필요하며, 예산이 한정된 상황하에서 합리적인 투자계획조정을 통한 체계적인 투자가 이루어져야 할 것으로 판단된다.

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.
