摘　　要：探究城际出行网络的时间异质性及其影响机制,对推动区域内部不同城市的分工协同和一体化发展具有重要价值。文章基于百度迁徙数据,利用PPML(Poisson Pseudo Maximum Likelihood)重力模型和交互项检验方法,分析长三角地区工作日、周末和节假日城际出行网络特征,并挖掘城际出行时间异质性的影响机制。结果表明:1)长三角地区城际出行具有明显的时间异质性特征,表现为工作日城际出行强度最低,周末倾向短途出行,节假日城际出行强度最高的特点;2)城际出行受到推拉力和中间障碍的影响作用。城市发展水平、个体出行诱因等推拉力要素对城际出行具有促进作用,出行成本和行政文化壁垒等中间障碍因素对城际出行具有阻碍作用,推拉要素的作用效果在不同时段具有差异性。Under the influence of information technology and high-speed transportation networks,which compress space and time,the region's population has achieved large-scale fluidity.Examining the temporal heterogeneity of intercity travel networks and its influencing mechanism can help optimize regional spatial organization and provide a scientific basis for regional integrated development.Based on Baidu migration data from January to April 2023,this study uses a PPML(Poisson Pseudo Maximum Likelihood)gravity model and interaction term testing to compare the scale,pattern,and influencing factors of intercity travel networks during weekdays,weekends,and holidays in the Yangtze River Delta region.The results indicate the following:1)The intercity travel network in the Yangtze River Delta region exhibits temporal heterogeneity characteristics.During weekdays,intercity travel primarily consists of cross-city commuting and business trips,with the lowest daily average scale.This forms a V-shaped intercity travel structure covering Shanghai,southern Jiangsu,Northern Zhejiang,and Southern Anhui.The positive effects of destination city population size and economic status on intercity travel are enhanced.On weekends,intercity travel is dominated by business trips and leisure activities,and residents tend to take shorter trips,which means that intercity distances pose greater hindrances to intercity travel.During holidays,intercity travel is primarily for leisure and entertainment and for visiting friends and relatives,with the highest daily intensity.The promotional effect of destination city population size on intercity travel is weakened,and intercity travel is less hindered by intercity distances.Compared to the effects of geographical distance,economic status,and population size on the scale of intercity travel during weekdays,travel duration,or geographical distance,tends to pose a greater hindrance on weekends and a lesser hindrance during holidays.The promotional effect of economic status is intensified on weekends but dimin
