基于复杂网络模块分析的区域物流协同效应研究

Analysis on the Synergy of Regional Logistics Based on Complex Network

本文创新性地引入复杂网络模块化分析,该方法可以通过建模将区域物流网络中具有相同增长趋势的地区区分开来,模块数越少说明网络整体的相似度越高。本文选取2005~2019年区域物流发展的相关指标数据,利用结构熵权法计算出各区域物流的综合水平,然后利用复杂网络刻画出中国各省、自治区和直辖市之间物流发展的相关性,最后根据各区域物流相关性的强弱进行模块化分析。结果表明,中国区域物流发展的协同性较高,且区域物流间平均相关性整体呈上升趋势。

Regional coordinated development is one of China’s major development strategies in the new era,and the coordi⁃nated development of regional logistics is the basis for the coordinated development of regional economies.The article innovatively introduces the modular analysis of complex networks.This article method can distinguish regions with the same growth trend in the regional logistics network through modeling.The smaller the number of modules,the higher the overall similarity of the network.first selects relevant indicator data of regional logistics development from 2005 to 2019,uses the structural entropy method to calcu⁃late the comprehensive level of regional logistics,and then uses complex networks to depict the relevance of logistics development a⁃mong China’s provinces,autonomous regions,and municipalities.Finally,perform modular analysis based on the strength of the regional logistics relevance.The results show that the development of regional logistics in China is highly synergistic,and the ave⁃rage correlation between regional logistics is on the rise as a whole.
