摘要:

借助连锁网络模型和复杂网络理论,基于2014年中国装备制造业企业的地理分布情况,分析城市空间组织关系。研究发现,全国各地城市呈现一种枢纽—网络结构。全国范围来看,北京为全国性枢纽城市,上海、深圳、重庆等城市为地区性枢纽城市,且枢纽城市之间以北京与深圳的城际连接最为密切,西北地区和西南地区的大部分城市在网络中连接程度相对较低。基于行业的子网络进行比较发现,不同行业在网络规模、枢纽城市和网络密度等方面都存在显著的差异,证实了城市空间组织的枢纽—网络结构具有多中心性和多样性的特点。运用复杂网络理论进行蓄意攻击实验发现,删除枢纽城市的腹地城市后其网络连通度基本不受影响,但删除其非腹地城市后网络联通度下降非常明显,说明空间距离对枢纽与节点连通的限制越来越弱,这与中心—腹地结构中的情形有着明显的区别。

Abstract:

Based on the interlocking network model and the complex network theory, this paper analyzes the spatial distribution and interaction of cities based on geographical distribution of equipment manufacturing enterprises. The study indicates that cities all over the country present a hub-network structure. Beijing is the national hub city of the network. Cities such as Shanghai, Shenzhen, and Chongqing are regional hub cities. Beijing and Shenzhen have the strongest intercity connection in the network. Most cities in the northwest and southwest have a relatively low connection with other cities in the network. By comparing the sub-networks of different industries, it is found that there are significant differences in network scale, hub city and network density, which proved the polycentricity and diversity of urban space organizational hub-network structure. Finally, complex network theory is used to deliver deliberate attack experiments. The experimental results show that the network connectivity is basically not affected when the hinterland of the hub city is deleted, while the network connectivity declines obviously when the non-hinterland of the hub city is deleted. This indicates that the restriction of spatial distance between hubs and nodes is getting weaker, which is significantly different from the central-hinterland structure.
