港口对腹地城市经济增长的空间溢出效应研究

将港城关系研究视角拓展至空间维度,利用2003—2016年中国沿海港口数据和城市数据,采用空间面板模型实证检验港口对腹地城市经济增长的影响.结果表明:港口不仅产生地区内溢出,也产生空间溢出;不仅促进所在城市经济增长,对腹地城市经济增长也具有显著的空间溢出效应;2008年金融危机后,港口空间溢出效应的显著性大幅增强;分区域检验中,环渤海港口对所在城市经济增长有明显的促进作用,但港口对腹地城市的空间溢出效应有限.

Spatial Spillover Effects of Ports on Economic Growth of Hinterland Cities

This paper extends the research perspective of port-city relationship to the spatial dimensions. Using the 2003 to 2016 coastal ports and cities data in China and spatial panel model, this study empirically investigates the effects of ports on hinterland cities' economic growth. The results indicate that ports not only create intraregional spillovers, but inter-regional spillovers. The existence of port not only promotes the economic growth of the city where it locates, but also has a significant impact on the economic growth of hinterland cities. The spatial spillover impacts of port have increased significantly after the 2008 global financial crisis. The results of subregional test shows that the port around the Bohai Sea plays a significant role on promoting the economic growth of the city, but the spatial spillover effects of the port on hinterland cities are limited in the subregional test.
