Relationship Model of Influencing Factors of Port Operation Efficiency in Yangtze River Economic Belt
As a key node connecting land of water transportation and cargo transshipment,the operation efficiency of port affects the circulation efficiency of modern logistics supply chain.This paper takes 12 major container ports along the Yangtze River Economic Belt as the empirical analysis objects,selecting shoreline length,number of berths,and yard area as input indi-cators,and container throughput and cargo throughput as output indicators,and the super-efficient SBM-DEA model was constructed to measure the port operation efficiency.The Tobit model is constructed to further analyze the quantitative relation-ship between internal and external influencing factors of port operation efficiency.The results show that the overall port operation efficiency in the Yangtze River Economic Belt shows an increasing trend,and the overall port operation efficiency and container port operation efficiency reached their peaks in 2014 and 2017,respectively.Among the factors affecting the efficiency of port operation,the port cargo throughput,container cargo throughput,port city GDP,and the proportion of the tertiary industry have a significant positive influence on the port operation efficiency,of which the tertiary industry has the most significant influence.Therefore,scaled and collaborative development of ports along the Yangtze River Economic Belt should be promoted to im-prove port operation efficiency,adjust the industrial structures to promote integrated growth of domestic and international trades;strengthen the hinterland economy and promoting mutual advancement between ports and industries.
