网络范式作为区域经济的建模工具：以希腊跨区域通勤为例
The network paradigm as a modeling tool in regional economy: the case of interregional commuting in Greece
摘要：
网络科学是一门新兴的学科，它使用网络范式将通信系统建模为互连节点及其链接（边）的成对集合。本文应用这一范式研究了区域经济中由日常劳动力运输流组成的相互作用系统，即所谓的通勤现象。特别是，通勤系统在希腊，包括39个非岛屿县建模为一个复杂的网络，并使用复杂网络分析和实证技术的措施和方法进行了研究。本研究旨在探讨希腊跨区域通勤网络（GCN）的结构特征，并解释该网络与区域发展的关系。该分析突出了GCN结构中空间限制的影响，它提供了关于过去十年建造的主要道路运输项目的见解，并概述了人口控制（重力）的通勤模式，说明人口稠密的地区吸引了大量的通勤活动，从而影响了他们的生产力。总之，本文突出了复杂网络分析在区域经济系统（如空间相互作用系统和交通网络系统）建模中的有效性，促进了网络范式在区域研究中的应用。
英文摘要：
Network Science is an emerging discipline using the network paradigm to model communication systems as pair-sets of interconnected nodes and their linkages (edges). This paper applies this paradigm to study an interacting system in regional economy consisting of daily road transportation flows for labor purposes, the so-called commuting phenomenon. In particular, the commuting system in Greece including 39 non-insular prefectures is modeled into a complex network and it is studied using measures and methods of complex network analysis and empirical techniques. The study aims to detect the structural characteristics of the Greek interregional commuting network (GCN) and to interpret how this network is related to the regional development. The analysis highlights the effect of the spatial constraints in the structure of the GCN, it provides insights about the major road transport projects constructed the last decade, and it outlines a populationcontrolled (gravity) pattern of commuting, illustrating that high-populated regions attract larger volumes of the commuting activity, which consequently affects their productivity. Overall, this paper highlights the effectiveness of complex network analysis in the modeling of systems of regional economy, such as the systems of spatial interaction and the transportation networks, and it promotes the use of the network paradigm to the regional research.
