Spatio-temporal evolution of the container port system along the 21st-century Maritime Silk Road

ABSTRACT

Research on the spatio-temporal evolution of the port system along the 21st-century Maritime Silk Road (MSR) can reveal the development law of ports. This study adopts the Herfindahl-Hirschman index, rank-size law, and an improved spatial and temporal correlation to investigate the spatial distribution and spatio-temporal correlation characteristics of container ports along the MSR during 2000–2019. The results show that 1) the distribution trends among port clusters have significant differences, and the gravity centre of the port system gradually shifts from Europe to Asia (market shares of European and Asian ports decline from 28.15% to 19.83% and increase from 63.80% to 66.78%, respectively); 2) the port system undergoes periodic ‘decentralisation–agglomeration–decentralisation’, and its structure gradually develops a ‘spindle’ or ‘olive’ shape; 3) the initial effect of MSR arises on the economic development of ports, and the spatial occupation ability of small- and medium-sized port clusters increases steadily; and 4) the spatial and temporal correlation gradually increases. The evolution of temporal correlation is more complicated with a bifractal structure in 2000–2010. This study can provide decision support for port development and thus clarifies the investment environment and construction of MSR.
