Abstract
This study investigates the impact of port investment along the 21st Century Maritime Silk Road on regional port network connectivity and its imbalance, using panel data from 21 key port cities over the period 2014–2023. The analysis reveals a significant positive relationship between port investment and network connectivity, with cargo throughput acting as a partial mediator. While port investment enhances operational efficiency and strengthens trade route resilience, the Gini coefficient analysis indicates substantial imbalances in connectivity, particularly in low-connectivity regions such as Guangzhou, Qinzhou, Lekki Deepwater Port, Abu Dhabi, and Dubai. These imbalances are attributed to economic disparities, insufficient funding, and inadequate infrastructure. The findings suggest that targeted investments in these regions are essential to improve connectivity and promote balanced regional development. This research provides valuable insights for policymakers and stakeholders aiming to optimize port investments, enhance regional trade networks, and ensure sustainable growth along the Maritime Silk Road.
