【摘要】：以中国286个地级及以上城市为基本研究单元,利用各城市间公路货运联系数据,采用社会网络法与GIS可视化对城际货运联系网络结构特征进行分析。结果发现,城市货运网络中心度的首位集中程度不高,少数城市节点对城市货运网络的支配不强,"长尾"分布特征相对较弱。区域网络中心度最高的城市大多数为省会城市,城市经济规模与网络中心度具有相关性。跨区城市货运网络受近邻效应影响,形成以广东、江苏、山东等地区的城市为主的联系格局,这些地区的城市与相邻地区货运联系较多。城际货运网络在空间组织上受距离衰减影响明显,各社团空间范围要大于城市群边界,与一些功能区范围相一致,社团中城市货运联系主要集中在东部地区。
[Abstract]:Taking 286 cities of China as the basic research unit, the network structure characteristics of intercity freight transport connection are analyzed by using the data of intercity road freight transportation, using social network method and GIS visualization. The results show that the first centrality of urban freight network is not high, the dominance of a few urban nodes to urban freight network is not strong, and the distribution of "long tail" is relatively weak. Most of the cities with the highest degree of regional network center are provincial capitals, and the scale of urban economy is correlated with the degree of network center. Due to the influence of the nearest neighbor effect, the cross-region urban freight transport network forms a connection pattern dominated by the cities in Guangdong, Jiangsu, Shandong and other regions, where there are more freight links between the cities in these areas and the adjacent areas. The intercity freight network is obviously affected by the distance attenuation in the space organization. The spatial scope of each community is larger than that of the urban agglomeration, which is consistent with the scope of some functional areas. In the community, the connection of urban freight is mainly concentrated in the eastern region.
