Cities are commonly recognized as the immediate hinterland of ports and play a crucial role in fostering the sustainable development of ports. Therefore, it is imperative to investigate the influence of cities on ports. By employing panel data from 2001 to 2021 for both ports and cities in the Bohai Rim region, this study examines the spatial spillover effect of urban economy on port efficiency using the spatial error model (SEM). The findings show that urban economies have a significant spatial spillover effect on port efficiency, but this effect diminishes across different spatial matrices. In particular, the geographical matrix demonstrates a stronger spatial spillover effect of the urban economy on port efficiency. These research findings help to establish a collaborative mechanism for port-city development and provide useful insights for government management decision-making.
城市通常被认为是港口的直接腹地，在促进港口的可持续发展方面发挥着关键作用。因此，研究城市对港口的影响至关重要。本研究利用环渤海地区 2001 年至 2021 年港口和城市的面板数据，采用空间误差模型（SEM）检验了城市经济对港口效率的空间溢出效应。研究结果表明，城市经济对港口效率具有显著的空间溢出效应，但这种效应在不同的空间矩阵中会减弱。特别是地理矩阵显示出城市经济对港口效率的空间溢出效应更强。这些研究结果有助于建立港城发展的协同机制，并为政府管理决策提供有益的参考。
