Increasing trade, the globalization of products and services, as well as the internationalization of specific firms have steadily accentuated the importance of export performance. This study examines the relationship between market orientation culture with three components including customer orientation, competitor orientation, interfunctional-coordination on increasing export capabilities through firm age and size. Using the data gathered from 111 selected firms over the period 2006-2010, the study has applied correlation ratios as well as structural equation modeling to examine various hypotheses. The survey has concluded that being market oriented increases market capabilities through increasing firm size and age.
