Temporality in the delimitation of functional regions: the use of mobile phone location data
利用手机定位数据，基于日常、非日常和周末人口流动的不同时间节奏，定义了功能区域的多种版本，并探讨了其层次结构，对区域划分研究有参考价值。
This paper evaluates the role of 'temporality' in defining functional regions.Functional regions are viewed as relatively closed in terms of selected population flows (or more generally concerning spatial interactions).They are usually defined by the daily commuting to work and are therefore commonly referred to as local labour market areas or travel-to-work areas.Using mobile phone location data, however, it is possible to work with population flows in a broader temporal and spatial context.Then we can talk about the temporality alternatives of functional regions depending on whether we base them on regular daily population flows, irregular daily population flows (which, according to the data analysis, are irregular from an individual's point of view but regular from a spatial unit's point of view between which they take place) or weekend population flows.Thus, several functional region's versions can be defined for a single regional system, where the different population movement's rhythm lengths movements limit their length and also determine their hierarchy.All functional regions' temporal alternatives according to mobile phone location data are defined based on data from the Czech Republic.
