摘要
以环渤海地区28个城市为研究对象,根据2020年统计数据,运用修正引力模型构建了环渤海地区物流网络,并通过社会网络分析法对网络结构特征进行了分析。结果表明:环渤海地区物流网络整体呈现“中部强,两翼弱”的空间布局特征;网络整体密度较高、关联性较好,形成了以北京—天津为双核心、以京津冀地区为核心区的“核心—半核心—边缘”结构;北京、天津所在凝聚子群的辐射作用突出,其他子群的结构稳定性较差,子群内外协作关系需要进一步完善。
Based on 28 cities in the Bohai Rim region,the logistics network in the Bohai Rim region is constructed by using a modified gravitational model based on the 2020 statistical data,and the network structure characteristics are analyzed by social network analysis method.The results show that the logistics network in the Bohai Rim region as a whole presents the spatial layout characteristics of“strong in the central part and weak in both wings”.The overall density of the network is high and the correlation is good,forming a“core-semi-core-edge”structure with Beijing-Tianjin as the dual core and the Beijing-Tianjin-Hebei region as the core area.The radiation effect of the condensed subgroup in Beijing and Tianjin is prominent,the structural stability of other subgroups is poor,and the cooperation relationship between the subgroup and the outside needs to be further improved.
