摘　　要：随着轨道交通建设进入平台期,其对于城市经济发展的实际效益越发受到关注。为了探究轨道交通发展对城市群的经济影响,通过建立一个表征城市多层次轨道交通的复杂网络模型,并基于该模型采用3个复杂网络指标,结合空间杜宾模型,检验轨道交通网络对城市经济发展的影响。研究结果表明,在城市群轨道交通网络中,具有更高可达性的城市,更加受益于轨道交通的发展,且轨道交通网络融合程度的提升能够对城市群中不同城市产生积极的溢出效应。这些结论有助于对新时期城市轨道交通网络规划建设提供建议。As the construction of rail transit enters a plateau phase,its practical benefits for urban economic development have become increasingly scrutinized.To explore the economic impact of rail transit development on urban clusters,a complex network model is constructed that characterizes the multi-level urban rail transit system.Utilizing three complex network indicators within this model,in conjunction with the spatial Durbin model,it examines how the integration level of the rail transit network influences urban economic growth.The research findings indicate that cities within the urban cluster rail transit network,which have higher accessibility,benefit more substantially from the development of rail transit.Furthermore,enhancing the network's integration level can generate positive spillover effects among different cities within the urban cluster.These conclusions offer valuable insights for the planning and construction of urban rail transit networks in the new era.
