This paper carry out a comparative analysis on management system of European countries and find implications for Korea. Through studying France, Austria, and Portugals case, we realized that assistance enforcement integration brings in enhanced ability to enforce and synergy effect via improving cost-efficiency, preventing overlapping business, and combining similar ones. Hence, according to such finding, it seems advisable to reform Koreas ODA policy to a separatd policy and integrated implementation model. This seems to be the most feasible and segmentation problem solving measure considering Koreas ODA size, operating system, and characteristics of aid types.
