摘　　要：高铁枢纽是引导城市空间发展的重要要素之一。本文以长江经济带37个高铁设站城市为例,构建高铁枢纽驱动城市重心转移指数模型,分析高铁枢纽驱动下城市空间扩展效应,并运用地理探测器揭示高铁枢纽驱动城市空间扩展的作用机制。结果显示:①高铁枢纽驱动长江经济带城市空间扩展效应分为3个等级,一是驱动城市重心大幅度向高铁枢纽方向扩展,呈现出“有的放矢”现象;二是驱动城市重心中幅度向高铁枢纽方向转移,呈现出“扩展萌芽”状态;三是驱动城市重心向高铁枢纽方向扩展不显著,没有呈现明显的“粘连”关系。②高铁枢纽驱动城市空间扩展效应的作用机制主要表现在城市能级、高铁枢纽发育程度、站—城关系和政府政策等4个维度11个因子,其中,城市能级发挥“推动力”作用,城市等级和城市外部可达性变化率两个因子作用明显;高铁枢纽发育程度发挥“牵引力”作用,枢纽等级因子作用明显;站—城关系发挥“催化剂”作用,枢纽可达性因子作用明显;政府政策发挥“指导力”作用。The construction of high-speed railway hub is one of the important elements to guide the spatial expansion of the city.Taking 37 cities with high-speed railway hubs in Yangtze River Economic Belt as examples,this paper constructs a model of high-speed railway hub-driven the city's center of gravity transit index,analyzes the spatial expansion effect of cities driven by high-speed railway hubs,and uses Geodetector to reveal the mechanism of urban spatial expansion driven by high-speed railway hubs.The results of this study showed that:(1)The spatial expansion effect of cities in the Yangtze River Economic Belt driven by high-speed railway hubs is divided into three levels:firstly,the cities'center of gravity is driven to expand significantly to high-speed railway hubs,showing a"targeted"state of expansion;secondly,the cities'center of gravity is driven to expand moderately to high-speed railway hubs,showing a"budding"state of expansion;thirdly,the cities'center of gravity is driven to expand inconspicuously to high-speed railway hubs,showing"no obvious adhesion"state of expansion.(2)The role mechanism of urban spatial expansion driven by high-speed railway hubs is mainly manifested in 4 dimensions and 11 factors,such as city level,the degree of development of high-speed railway hubs,and station-city relationship.Among them,city level plays the role of"driving force",and the factors of"city level"and"rate of change in external accessibility of cities"play a significant role;the degree of development of high-speed railway hub plays the role of"traction",and the factor of"high-speed rail hub grade"plays a significant role;the relationship between station and city plays the role of"catalyst",and the factor of"accessibility of hub"plays a significant role;the degree of government policy plays the role of"guidance".
