摘　　要：基础设施网络和经济网络可从不同的维度对城市系统进行刻画,两者存在密切联系,研究两者间的动态耦合关系对促进城市网络的形成和发展具有重要意义。文章利用2008—2023年高速铁路运营服务数据和上市公司关联交易数据,构建分别反映城市间高铁联系和企业异地投资联系的高速铁路服务网络(简称为“高铁网络”)与异地投资网络,应用象限图法和耦合协调度模型探讨了2种网络时空耦合协调性,识别城市和城市联系的类型。结果表明:1)高铁网络和异地投资网络的规模和密度均呈现快速增长态势,高铁网络扩张明显快于异地投资网络;高铁和异地投资网络整体上存在显著的正相关性,相关程度先上升后下降。2)高铁和异地投资网络同步发展的城市主要集中在东部地区行政和经济发达的城市;而高铁网络滞后的城市主要集中在珠三角经济发达地区的非交通枢纽城市以及大连、乌鲁木齐等;高铁网络超前的城市主要集中在中东部地区高铁干线周边城市。整体上,经济发达程度较高的地区,城市在高铁网络或异地投资网络中的地位越高,城市间的高铁和异地投资联系越强。Infrastructure and economic networks can be used to describe different dimensions of urban systems,and a close relationship exists between them.Therefore,it is important to study the dynamic coupling relationship between them to promote the formation and development of urban networks.Relevant studies have compared and analyzed the evolution characteristics of urban network structures from different dimensions;however,relatively few studies have focused on the dynamic coupling relationship between high-speed rail and remote investment networks.The formation and development of high-speed rail networks has become a key factor affecting remote investment networks,and the layout of a remote investment network also affects the development of a high-speed rail network.To this end,we used high-speed railway operation service data and related transaction data of listed companies from 2008 to 2023 to construct high-speed railway and remote investment networks reflecting intercity high-speed railway and enterprise remote investment connections,respectively.QAP correlation analysis was used to explore the overall correlation between the two networks.Using the quadrantal diagram method and the coupling coordination degree model,we discuss the spatiotemporal coupling coordination of the two networks,identify the types of cities and urban connections,and propose operational planning suggestions for cities and high-speed railways.The results indicate the following:1)Both the scale and density of the high-speed rail network and the off-site investment network show a rapid growth trend,and the expansion of the high-speed rail network is significantly faster than that of the off-site investment network.There is a significant positive correlation between high-speed rail and the remote investment network as a whole,and the degree of correlation first increases and then decreases.2)In terms of space,cities with the simultaneous development of high-speed rail and remote investment networks are primarily concentrated in the administrati
