The daily commuting out of the city of residence for labor purposes is a complex phenomenon driven by various geographical, transportation, economic, and social forces. Due to its high level of complexity, current modeling approaches are mainly disciplinary and thus lack a multifaceted approach incorporating diverse conceptualization of this phenomenon. To contribute to this demand, this paper develops a methodological framework integrating aspects of commuting of different contexts, functionality, and level of geographical resolution. The proposed framework builds on a complex network and principal component analysis first to develop a multilayer graph of interregional commuting, next to configure variables representing aspects of network topology, and finally to decompose the total model into principal components expressing uncorrelated aspects in the overall conceptualization of interregional commuting. The proposed framework conceptualizes spatial distance as a major force of network topology and develops a quantitative framework evaluating the consistency of network topology across layers of different geographical resolutions and functionality. The overall approach provides insights into the structure and functionality of interregional commuting and promotes the integrated macroeconomic approach in regional research.

多层空间网络拓扑中的降维:以希腊跨区域通勤为例

以劳务为目的的日常出城通勤是受地理、交通、经济、社会等多种力量驱动的复杂现象。由于其高度复杂性,当前的建模方法主要是学科性的,因此缺乏将这一现象的不同概念化的多方面方法。为了满足这一需求,本文开发了一个方法框架,整合了不同环境、功能和地理分辨率水平的通勤方面。所提出的框架建立在复杂网络和主成分分析的基础上,首先开发区域间通勤的多层图,然后配置表示网络拓扑方面的变量,最后将整个模型分解为表示跨区域通勤整体概念化中不相关方面的主成分。所提出的框架将空间距离概念化为网络拓扑的主要力量,并开发了一个定量框架,评估跨不同地理分辨率和功能层的网络拓扑的一致性。整体方法提供了对跨区域通勤的结构和功能的见解,并促进了区域研究中的综合宏观经济方法。所提出的框架将空间距离概念化为网络拓扑的主要力量,并开发了一个定量框架,评估跨不同地理分辨率和功能层的网络拓扑的一致性。整体方法提供了对跨区域通勤的结构和功能的见解,并促进了区域研究中的综合宏观经济方法。所提出的框架将空间距离概念化为网络拓扑的主要力量,并开发了一个定量框架,评估跨不同地理分辨率和功能层的网络拓扑的一致性。整体方法提供了对跨区域通勤的结构和功能的见解,并促进了区域研究中的综合宏观经济方法。
