“…Most of the studies were performed in Europe, mainly in EU-15 countries (Spain, Greece, Portugal, Sweden, Netherlands, Italy, Austria, Germany) and UK ( To analyze the most significant capabilities as export performance determinants, authors categorized them and synthesized how often the factor was used in studies and what kind of effect was found on export performancepositive, negative, no effect of other type of effect (Table 2).

Although these factors have proved to have mostly positive effect on performance, marketing capabilities show the largest frequency of results with no effect or negative effect on export performance.…”
