To reveal the evolution characteristics of the spatial distribution pattern of ports along the 21st-Century Maritime Silk Road(MSR), this paper describes them from time and space perspectives based on the methods of spatial autocorrelation and temporal-spatial correlation dimension, which provides theoretical support for clarifying the investment environment planning, layout of ports and the construction of the MSR. The results show that: 1) The distribution pattern of port system along the MSR has certain spatial correlation, the difference of container throughput is gradually narrowing. The spatial pattern of port container throughput presents the characteristics of marginalization and the phenomenon of club-convergence. The centre of gravity of port system has gradually shifted from Europe to Asia, especially to East and Southeast Asia. 2) The correlation between port clusters based on spatial and temporal distances is gradually enhanced, the temporal correlation is more obvious and the evolution process is more complex. The spatial-temporal correlation levels among port clusters are not completely consistent with the "distance attenuation law". 3) Overall, there is a hierarchical distribution pattern in the port system, and there are multiple hubs in some port clusters. The connection between port clusters along the MSR shows the networking tendency.
