Variables used in the analysis.

The rapid development of mobile internet technology and the widespread adoption of smartphones have significantly influenced people’s daily lives and complicated the mechanisms affecting urban rail transit travel behavior. While existing studies focus predominantly on developed countries, research remains limited in megacities in developing nations experiencing rapid technological growth. Using questionnaire data from urban rail transit travelers in Chongqing, China, this study investigates the intrinsic relationship between mobile internet and residents’ urban rail transit travel behavior, along with its underlying mechanisms. Key findings reveal that: 1) Transportation infrastructure and management informatization directly influence residents’ urban rail transit travel behavior; 2) Transportation services informatization exerts indirect effects; 3) Information literacy and resources mediate the influence of transportation informatization on urban rail transit travel behavior. These findings not only enhance the understanding of how mobile internet is transforming urban rail transit travel behavior but also provide a theoretical foundation for optimizing urban spatial organization in the future.

移动互联网技术的快速发展与智能手机的广泛普及，已深刻影响民众日常生活，并使得影响城市轨道交通出行行为的作用机制愈发复杂。尽管既有研究多聚焦于发达国家，但针对技术迭代快速的发展中国家特大型城市的相关研究仍较为匮乏。本研究依托中国重庆市城市轨道交通乘客的问卷调查数据，探究移动互联网与居民城市轨道交通出行行为之间的内在关联及其作用机理。核心研究结果显示：1）交通基础设施与管理信息化直接作用于居民城市轨道交通出行行为；2）交通服务信息化则发挥间接影响；3）信息素养与信息资源在交通信息化对城市轨道交通出行行为的影响中起到中介效应。上述研究结果不仅深化了对移动互联网如何重塑城市轨道交通出行行为的认知，更为未来优化城市空间组织提供了理论支撑。
