This study explores the impact of participating in five major online export support programs currently being implemented by the Ministry of SMEs and Startups on online exports of SMEs in 2018-20. The main findings show that the online export support program appear to significantly have improved the online export-related performance of participating SMEs in a short period of time. In addition, the online export support program’s online export enhancement effect tend to be relatively greater when the participating SMEs have relatively little experience with online export and low sales volume. Manufacturers also appear to benefit from support programs more than resellers. In summary, the findings suggest that Korea’s online export support policy has had a significant impact in providing incentives for SMEs to start/increase online exporting.
