This study explores the conceptual investigational foundations of how two existing concepts of supply chain exploitative practices and supply chain explorative practices together may further inform the balanced theory of port competitiveness (BTOPC). The defined and validated factors of the BTOPC are further investigated via the lens offered by ambidextrous supply chain strategy, which is defined and measured through the simultaneous practice of exploitative and explorative activities. The exploratory nature of this study aims to help academics to further the theory of port competitiveness and assist practitioners in improving port management. Eight in-person interviews with practitioner and academic port experts were conducted in addition to follow-up telephone conversations. This study finds that supply chain exploitative and explorative practices indeed offer a unique vantage view for assessing the port competitiveness when utilizing the BTOPC factors.
