To accelerate the coordinated development of ports,the spatial spillover effects of Chinese ports are measured to judge the competition and cooperation relationship among ports from the perspectives of coastal ports as a whole and port clusters based on the spatial Durbin panel model,and the spatial effect decomposition method is used to analyze the potential economic motivation behind the competition and cooperation among ports.The findings reveal that:Chinese coastal ports as a whole exhibit a negative spatial spillover effect,and there exists a certain degree of competitive dynamics among ports;from the perspective of port clusters,the extent and nature of spatial spillover effects exhibit variations in different port clusters.The Yangtze River Delta port cluster displays a positive spatial spillover effect,with inter-port relations dominated by cooperation;the Bohai Rim port cluster and the southwest coastal port cluster demonstrate a negative spatial spillover effect,with inter-port relations dominated by competition;the spatial spillover effects in the statistical sense are not observed in the southeast coastal port cluster and the Pearl River Delta port cluster.In general,the investment of port cities in fixed assets,GDP per capita,the contribution rate of the tertiary industry to GDP and the total export-import volume are important economic factors to promote port development.The influence of relevant economic factors on port spatial effects also varies across regions.
