摘要: 以中原经济区县级行政单元为网络节点,利用重力模型测算1996 年、2010 年231 个节点间的经济联系强度,分别取各个节点对外联系强度第1 位、前5 位、前10 位的连接建立经济联系网络,运用GIS 工具和社会网络分析方法分析网络的空间格局与演化特征。研究发现:① 中原经济区经济联系网络发育不平衡,节点度分布呈明显的右倾“斜长尾分布”特征,少数节点掌握着绝对的“网络权力”,郑州市为整个网络的首位核心,洛阳市、邯郸市为副中心;网络中部、北部节点间连通情况相对较好,而东、南两个方向上节点连通能力亟需提升。② 核心、边缘节点网络权力差距进一步扩大,2010 年节点度值基尼系数和集中度指数比1996 年均有明显提高,边缘区节点连通能力不足且进一步弱化,不利于中原经济区同毗邻地区的互动发展。③ 网络呈现多重轴—辐结构,郑州市为一级枢纽,洛阳市、邯郸市、漯河市等为二级枢纽;中原经济区正在建设的“十”字形发展轴和“米”字形发展带,有助于巩固一、二级枢纽间的经济联系,并使整个经济区实现优势互补、联动发展。④ 网络中的“掮客”节点主要位于中原城市群板块中,因此中原城市群发展对提高网络整体连通能力有很大作用。

Abstract: The Central Plains Economic Zone is an important engine of the central plains rising strategy, and it is also the strategy fulcrum of the regional coordinated development. Building a scientific and reasonable regional economic relation network is an important part of the construction of the Central Plains Economic Zone. This paper takes the CentralPlainseconomiczone as astudy area and its counties as the network nodes. The economic relation intensity among 231 nodes in 1996 and 2010 are calculated based on the gravity model. The regional quantity in the model is represented by the geometrical mean of GDP and population of the nodes. The GDP of 2010 have been deflated to the price level of 1996. The distance coefficient is represented by the shortest journey time by highway between the cities. Economic linkage network has been built in terms of the first, top5 and top10 in connecting intensity of each nodes, using the tools of GIS and method of Social Network Analysis to analyze the spatial pattern and evolutional characteristics of the network, and the analysis is mainly based on the concept of degree, degree distribution, clustering coefficient and betweenness centrality, etc. The results show that: (1) The CentralPlainseconomiczone has an unbalanced economic linkage network, and the distribution of the node degree exhibit an obvious rightward "inclined long-tailed distributions". The number of nodes with degree less than or equal to the median accounts for more than 85% of the total number of nodes, and a small number of nodes hold the absolute network power. Zhengzhou is the center of the network, while Luoyang and Handan are the sub-centers. The connectivity of the central and northern nodes is relatively strong, while measures should be taken to increase the connectivity of the eastern and southern nodes. (2) The network power gap between the central and marginal nodes is further widening, and the Gini coefficient and concentration ratios (CR1,CR5,CR10) of the node degree have increased significantly from 1996 to 2010.Thenetworkpowerofthecorenodesfurther increases, whilethe connectingabilityofthemarginalnodesdeclinesgradually. Theunbalancednetworkdevelopment is more pronounced,and this will restrain the interactional development between the CentralPlainsEconomicZone and its adjacent regions.(3) The network has a multiple hub-and-spoke structure. The correlation between the node degree and clustering coefficient is significantly negative. This proves that the nodes with high degree are the main connection objects of the adjacent nodes, while there are fewer mutual connections between the peripheral nodes. With the high degree nodes as the core, the network formed several sub-networks with hub-and-spoke structure of different levels. Zhengzhou is the primary hub, and plays as the core leading role for the entire economic zone, while Luoyang, Handan and Luohe are the secondary hubs, mainly playing the roles of leading and radiating for the surrounding cities and counties. The construction of the cross-shape development axis and "米" glyph development zone will strengthen the economic linkage between the primary hub and the secondary hub, it will also help the entire region to realize the advantageous complementarities and linkage development. (4) The broker nodes play an important intermediary role in the network connectivity, and the betweenness centrality is not only closely related to the node degree, but also influenced by its location in the network. The broker nodes in the economic linkage network of the Central Plains Economic Zone are mainly located in the Central Plains City Group, so the development of the Central Plains City Group will have significant impact on improving the whole connectivity of the network.
