I investigate the export performance of firms from emerging economies based on resource based view (RBV) of a firm. Based on review of extant literature, I identify firm size, research and development expenditure, advertising expenditure and business group affiliation to be important antecedents of level of exporting activities of a firm. I utilize a two-stage least square estimation (G2SLS) on a sample of 47,140 firm-year observations over a period of sixteen years from 1990–2005. The findings suggest that export sales and domestic sales are interdependent and affect each other. R&D expenditure and business group affiliation positively affect export sales, however advertising expenditure negatively affects export sales.
