For decades, the notion of ‘Free Zones’ has remained complex and ambiguous. Despite considerable efforts in this regard, the concept of ‘Free Zones’ and its components have not been sufficiently explored. To further consolidate the related literature, this study conducted a literature review on the terminology of the Free Zone and its components using a systematic review method based on literature and international organizations such as the UNCTAD. This study provides needed general knowledge about the nature of Free Zones. It also presents the classifications and types of economic zones, and provides insight into what distinguishes Free Zones and economic zones from one another. Furthermore, it aggregates the Free Zone into its constituting components, concluding with insight into future research by identifying relevant challenges and gaps.
