최근 3차원 공간정보와 행정정보를 융합하여 다양한 도시문제의 과학적 해결을 지원하는 디지털트윈이 공공분야의 스마트시티와 공간정보 행정업무에 도입되고 있다. 이 연구의 목적은 공공분야에 디지털트윈을 확산하기 위해 필요한 공간정보의 정책방향을 제시하는데 있다. 먼저, 이론적 고찰을 통해 디지털트윈에 대한 개념을 검토하였고, 언론보도 등에 나타난 디지털트윈에 대한 주요 키워드를 도출하였다. 두 번째, 디지털트윈 국가정책과 디지털트윈국토 지자체 시범사업, 공공기관의 디지털트윈 사업 특성을 고찰하였다. 세 번째, 정책 및 제도적 관점, 사업적 관점, 활용성의 관점에서 공공분야 디지털트윈이 어떠한 이슈와 문제점을 가지고 있는지 도출하였고, 이를 해결하기 위한 정책방향을 제안하였다. 이 연구의 결과는 향후 공공분야 디지털트윈 확산을 위한 정책적 시사점을 제공할 것이다.

This study identifies influential factors for invigorating the public management office (PMO) system for system integration (SI) projects in public sectors and analyzes the priority of each factor from the point of different stakeholders, i.e., owners, SI company, and PMO. Based on the literature review, four first-level influential factors are identified: legal system maintenance, owner’s capability, SI company’s capability, and PMO’s capability. Among them, the PMO’s capability is determined as the most critical factor by all the stakeholders. Among the second-level influential factors, the capabilities of professional engineers and project managers are considered as important among the PMO’s capability, whereas the reasonable consulting fee is considered as the most critical factor among the legal system maintenance. With respect to each stakeholder, project management capability is considered as the most important factor for owners, while the reasonable consulting fee is considered as the most important factor for PMO.

This study aims to empirically examine the effect of foreign direct investment (FDI) and corruption on the development of public-service sectors in 10 ASEAN countries. It then investigates whether this relationship is different between two FDI compositions including greenfield FDI and FDI in the form of cross-border merger and acquisitions (M&As). Using a panel database of 10 ASEAN countries during the period 1996-2015 from various sources including the World Development Indicators of the World Bank and UNCTAD, we first find that FDI strongly and positively contributes to the development of the public-service sectors in the recipient nations, except for the electricity sector. However, we show that this relationship is dependent on the type of FDI modes of entry. Specifically, while greenfield investment exerts a beneficial influence on the development of telecommunication and transportation sectors, cross-border M&A has no effect on these sectors, perhaps because of the distinct differences among three public service sectors. Finally, we found that in a highly corrupt environment, aggregate FDI might have no influence on all three public-service sectors, possibly because the two contradictory influences of the interaction terms between corruption and two FDI sub-types seem to cancel each other out.
