In order to explore the spatio-temporal characteristics of urban global linkage networks of sports events,it applies the methods of social network analysis and spatial analysis to study the characteristics of the spatio-temporal evolution of the global sport linkage networks and their influencing factors based on the data of Boston Marathon participants in 2010-2019.The results show that:1)The number of countries(regions)from which Boston Marathon participants came increased from 71 in 2010 to 99 in 2019,and the number of participants increased from 26000 to 30000,with a fluctuating upward trend in the network size.2)The density of the global sport linkage network of Boston Marathon became larger(0.551→0.787),the weighted average degree increased(32.41→60.31),network heterogeneity decreases(0.497→0.415).3)Nodes of the global sport linkage network are mainly distributed in Europe and the Americas,followed by Asia,Africa is less,Oceania is unchanged.4)The global sport linkage network of Boston Marathon with countries(regions)has generally increased,especially Canada,Mexico and Europe,followed by Asia.Africa's connection with Boston is increasing slightly.5)Globalization level,economic factors,cultural factors,social factors,and transportation factors are the main factors influencing the spatial-temporal evolution of the global sport linkage network in Boston.
