摘要(Abstract):

城市的发展不仅表现为城市规模的扩大,更体现在城市空间系统的协调发展。信息空间和经济空间作为城市空间系统的重要子系统,在城市发展的过程中相辅相成,不断为城市发展注入新活力。该文建立了基于城市流模型的信息空间和经济空间测度模型,对信息空间和经济空间进行了相关性分析,验证了空间节点的耦合性和联系的耦合性,建立了整体复合网络,提出了基于中心度策略的枢纽网络模型,在此基础上耦合生成信息空间和经济空间的枢纽网络,并将网络叠加复合生成空间综合枢纽网络,借助社会网络分析工具(UCINET)对综合空间网络进行深入探讨。研究发现:信息空间网络中的中间中心度普遍较小,空间网络的效率较低,经济空间的核心布局整体为"东-南-西-北"四轴联动发展,带动整个城市经济空间的繁荣;信息空间枢纽网络主要分布于东部和西部地区,形成以东部沿海城市为主以及西部西安、重庆和成都三核心的信息空间核心格局;而经济空间西部中心向中部偏移,形成以武汉为核心的中部城市核心格局。信息强空间和经济强空间呈现正向耦合性,网络的耦合程度较高,空间节点的信息化和经济化相互依赖性较高。
Urban development shows not only the expansion of city size,but also the coordinated development of the urban space system.As the important subsystems of urban system,information space and economic space complement each other in the process of urban development,injecting new vitality into urban development.In this paper,an information space and economic space measurement model based on urban flow model was established,and the correlation analysis was done to verify the coupling of the space nodes and the links between nodes,and furthermore an overall comprehensive composite network was established.In addition,a hub network model was proposed based on the centrality degree index.On the basis of the foregoing discussion,hub networks of the information space and economic space were coupled and then superimposed to a new coupled mix hub network,and in-depth discussion of the mix hub network was conducted by using UCINET.The results show that the centrality of the information space network has serious long tail effect with less efficiency.The core layout of the overall economic space appears " East-South-West-North" axis development,driving the prosperity of the urban economic space.Information space hub network is mainly distributed in the eastern and western regions,forming the pattern of giving priority to the eastern coastal cities and followed by Xi′an,Chongqing and Chengdu in the West China;the western center of the economic space moves to the midlands,with Wuhan as the core of the middle cities.There is a positive coupling between strong information space and strong economic space.The coupling degree of the network is high,and the information and economy of space nodes are highly dependent on each other.
