通勤行为是城市地理学的重要研究内容。国家以城市群为城镇化主体的发展战略、信息技术的快速发展和交通设施服务的提升促使跨界地区成为城市间协同发展的“桥头堡”，重塑了该地区居民通勤行为与通勤空间的关系。但既有研究对跨界地区新的通勤行为和模式分析尚不充分，特别需要从微观居民层面进一步探究跨界地区的通勤行为和通勤模式及其影响机理。本项目以广佛跨界地区为例，利用手机信令数据和居民出行调查数据等，将空间分析和计量模型方法相结合，刻画跨界地区居民通勤行为的时空间特征，梳理和总结跨界地区居民的通勤模式；寻找居民在时间和空间上通勤行为和模式的差异，挖掘其演变过程；着重强调政策、技术、客观环境与居民主观因素交互作用下的行为机制建模，构筑居民社会经济属性、区域发展政策、信息和交通技术与居民通勤行为的关系框架，深入挖掘跨界地区居民通勤行为的影响机制，从时空行为视角为区域协同发展提供科学的参考和依据。

Commuting behavior is an important topic of urban geography. The national development strategy of urban agglomeration, the rapid development of information and technology and the improvement of transportation facilities and services have made cross-border regions become "bridgeheads" for the coordinated development among cities and reshape the relationship between commuting behavior and commuter space. However, the existing research on the commuting behavior and pattern in cross-border regions is not enough, and it is necessary to further explore commuting behavior and commuting pattern and its influencing mechanism in the cross-border regions from the micro level. Taking Guangzhou-Foshan cross-border region as an example, this project tries to combine the methods of spatial analysis and statistic models, using mobile phone data and resident travel survey data, to characterize the spatial and temporal characteristics of commuting behavior in cross-border regions, to identify the differences of commuting behavior and modes of residents from time and space perspective, and to excavate the evolution process. The research emphasizes the influential mechanism under the interaction between policy, technology, objective environment and subjective factors of residents. The research also constructs the analytical framework between residents attributes, regional development policy, information and communication technology and resident commuting behavior, and deeply explores the influence mechanism of commuting behavior of residents in cross-border regions. The research will provide some scientific reference and basis for regional coordinated development from the perspective of spatial and temporal behavior.
