移动通信使用行为对省内与跨省出行行为的影响研究

民众出行行为与多维度的经济社会活动密切相关，探究其影响因素有助于促进消费升级和区域经济流通。本文基于一套独特的电信大数据，探究移动通信使用行为对省内与跨省出行的影响及相应的作用机制。研究利用用户省内、省外漫游记录精准识别其省内、跨省出行行为，并将移动应用（包括影视娱乐、生活服务、购物支付类应用）和传统语音短信使用行为与出行行为进行关联分析。实证结果显示，移动应用使用行为显著促进用户省内出行，这一效应通过移动应用依赖度产生中介作用（中介效应占比为8.45%—17.70%）;传统语音短信使用行为则显著促进用户跨省出行，且该效应通过社会资本发挥中介作用（中介效应占比为29.95%）。结果说明移动应用通过提供便利服务，扩展用户活动边界，促进用户省内出行；而传统语音短信通过构建深层社交关系，积累社会资本，为用户提供社会支持和情感资源，降低跨省出行伴随的不确定性，促进用户跨省出行。

Individual mobility behavior is closely related to diverse economic and social activ- ities. Identifying its influencing factors is conducive to promoting consumption upgrading and coordinated regional economic development. Based on a unique set of telecommunication big data, this study empirically examines the impact of mobile communication usage behavior on intra-provincial and inter-provincial travel behaviors, as well as the underlying mechanisms. By analyzing users' intra- and inter-provincial roaming records, the study accurately identifies their travel behavior and incorporates mobile application usage (e.g., video entertainment, life ser- vices, shopping and payment) and traditional voice/SMS usage into the model for analysis. The results show that mobile application usage significantly promotes intra-provincial travel, with a mediating effect exerted through mobile application dependence (mediating effect accounting for 8.45%-17.70%). In contrast, traditional voice/SMS usage significantly promotes inter-provincial travel, with the mediating role played by social capital (mediating effect accounting for 29.95%). Mobile applications promote intra-provincial travel by offering convenient services and expand- ing users' activity boundaries, while traditional voice/SMS usage fosters deep social ties and accumulates social capital, thereby providing social and emotional support that reduces the un- certainty of inter-provincial travel.
