The development pattern and evolution of China's ports based on the composite index of freights,passengers,and transport
As one of the key platforms for China's opening up,ports play an increasingly important role in promoting the construction of the Belt and Road.In order to reveal the development pattern of Chinese ports,this paper constructs a composite index using the data on the import and export of freight volume,entry and exit of passenger volume,and inbound and outbound transport volume at ports from 2011 to 2020.Based on the composite index,the evolution of ports'development pattern is further depicted and analyzed from the perspective of stock and increment.The results show that:(1)The number of ports is gradually increased,promoting the port system to be increasingly improved.The volume of freight imported and exported through the ports is on the rise as a whole,while the scale of the entry-exit person and transport declined significantly in 2020.(2)From the perspective of stock,the composite index shows a fluctuating rise with 2017 as the breakpoint.Among them,the eastern port system is in a transitional period of high-quality development,while the western port system has a strong latecomer's advantage.However,there are still imbalanced and insufficient development challenges at the northeast and central port systems.In terms of the development model,the northeast ports show the emerging characteristics of high growth rate and low scale share as a whole;the eastern ports are relatively mature with low growth rate and high scale share;the central ports face the dual dilemma,while the western ports have the superimposed advantages of high growth rate and large scale share.(3)From the perspective of increment,it is found that seaports exhibit the largest G increment overall,and river ports have the strongest overall growth competitiveness.According to the traditional SSA model for the entire period,the growth of airports mainly relies on the scale advantage of the base period share,while railway and highway ports are at a disadvantage in terms of both actual increment and growth competitiveness.Based on the phased dynamic SSA model of three stages from 2011 to 2014,2014 to 2017,and 2017 to 2020,the results demonstrate that the quantitative development model driven by base period scale in the past has encountered significant obstacles in recent years.The dynamic growth disadvantage of seaports is gradually narrowing and developing towards a positive trend,but other types of ports have not yet formed a high-quality development model driven by growth rates.
