Analyzing regional disparities in dry port benefits

초록

PurposeDry ports can enhance port-hinterland connectivity while offering environmental benefits, but their contributions vary depending on port characteristics, spatial settings and inland network locations. Additionally, tightening environmental regulations in the shipping industry may increase regional disparities in the benefits of dry ports. This study examines the impact of environmental policies and dry port operations on regional disparities in dry port benefits.Design/methodology/approachA utility-based cost model evaluates accessibility to seaports in China's Bohai region under two scenarios: (1) direct road transport and (2) intermodal road-rail transport via dry ports. The difference in generalized cost measures between the two scenarios is considered to be the benefit of dry ports for the corresponding city.FindingsThis study reveals that while dry ports improve overall connectivity and provide economic and environmental benefits, these benefits are unevenly distributed across the hinterlands. Factors such as proximity to dry ports, frequency of rail services and cargo time value play significant roles in influencing accessibility. Furthermore, the implementation of carbon tax policies enhances the advantages for cities with efficient dry port operations.Research limitations/implicationsData reliance and uniform cost assumptions introduce biases. Future research should employ comprehensive data and assess green technologies to advance sustainable logistics at dry ports.Practical implicationsPolicymakers can leverage these findings to guide dry port investments and design equitable environmental policies.Social implicationsEquitable port access fosters economic growth and sustainable development in hinterland communities.Originality/valueThis study advances how dry ports and environmental regulations jointly shape regional logistic benefits, offering a framework for more informed decision-making in port-hinterland planning.
