Abstract

Economic corridors are long-term projects that must address challenges beyond physical infrastructure to become fully operational. Most of these challenges, including institutional coordination, logistical integration, and creating favorable conditions for trade and investment, require complex networks of interaction among the corridor agents. This study analyzed the actor network within the Bioceanic Road Corridor (BRC) "Mato Grosso do Sul—Ports of northern Chile" to assess how their roles and interactions influence the development of the project. Based on 240 surveys and the application of social network analysis (SNA), we mapped key relationships within the BRC. Our contributions extend the analysis of economic corridors from a relational space perspective, highlighting the influence of key actors in shaping the development of these projects. Our findings reveal poor coordination between the private sector and subnational public agencies, threatening the corridor’s success. Limited private sector involvement restricts opportunities for regional economic growth, investment, job creation, and trade. Additionally, weak coordination among subnational actors worsens institutional fragmentation, hindering the implementation of policies aligned with local needs. To avoid BRC becoming a "white elephant," institutional coordination must improve and incentives for private sector participation—such as public–private partnerships, tax incentives, and investment programs—are essential to unlock its potential for regional development. © The Japan Section of the Regional Science Association International 2025.
