Despite abundant research, we lack systematic knowledge on the effects of export promotion programs (EPPs). Extant research is largely fragmented and shows contradictory results. To fill this void, the present paper systematically reviews 192 articles to develop a system-based taxonomy and conceptual model of export promotion comprising six main components: system inputs, outputs, firm resources and capabilities, strategies, managers’ characteristics, and networks. The review contributes to extant research by taking stock of the current state of knowledge on the role of different EPPs in companies’ internationalization process. Furthermore, it reveals research gaps that chart important directions for future studies.
