Purpose - The purpose of the present study is to discover success factors for small and medium-sized exporting enterprises and to derive factors that can positively influence the export of small and medium-sized enterprises. The ultimate goal is to contribute to the problem solution mentioned above. Research design, data, and methodology - A total of 258 filled-in questionnaires were collected; afterwards, frequency and cross tabulation analyses were conducted. The PPML analytic technique was applied to the core factors analyzed in Stages 1 and 2 to conduct regression analysis (cause and effect analysis and estimation method), thereby deriving success factors. Result - Based on detailed factors, a total of 15 success factors directly/indirectly involved in the success of export in small and medium-sized enterprises comprising 9 success factors, three positive effect factors for export, and three governments support policy factors were identified. Conclusions - The present paper is a rare empirical study paper that found and presented three detailed factors that positively influence on export and three government support policy factors, in addition to the above factors. Therefore, the results can be used by small and medium-sized enterprises that require not only previous studies, but also actual export success factor. KCI Citation Count: 6
