The Analysis Of Economic Network Structure's Evolution Characteristics In Hubei Province

In this paper, based on the space point, line and plane as the key elements analysis the economy of the network structure something about the node, relation and space organization's formation and evolution in Hubei province. By using the gravity model and social network to analysis the internal economic ties and economic network structure in Hubei province in 1994,2004 and 2014. And refers to the concept of spatial structure of the index, the spatial structure of three time node status was analyzed. The results showed:(1) Through the study of the comprehensive level of 76 nodes'economy evaluation in Hubei province, we found the first degree significantly higher than in other areas of Wuhan city. The center of Wuhan city is very important. The result determined the primary, secondary and tertiary center node, and those tertiary center nodes laid a solid foundation in the overall space structure. (2) By using the gravity model predicts the strength of internal economic ties in Hubei province. Since 1994, the differences between the east region and the Wuhan city which is center is big. The center of the economic ties has changed, in addition to,the Wuhan, Yichang, Xiangyang, Enshi, Shiyan, etc are becoming the center of the surrounding areas of economic ties. Wuhan megalopolis of the internal economic ties were more closely, keeping the surrounding space characteristics of Wuhan as the center. And through the economic contact analysis, something in Wuhan is changed. The radiation effect to the economy of the surrounding areas is strengthen than initial agglomeration effect. Weak western in Hubei regional economic ties which is based on relatively weak economic strength, internal produced in Enshi section, Shiyan as the center of local economic ties.(3) Economic network structure analysis is based on social network analysis method, such as the overall network density, the center line of the condensing subgroup analysis and spatial structure index. Based on the economic front contact intensity data, the calculation can be found, Hubei province's economy as a whole is in continuously strengthen the density of space structure, spatial organization and at the same time also appeared division of change. Began to appear the east, the southwest and northwest of Hubei space organization, the internal organization in the local small organizations. The Wuhan city as a center's situation effect has improved. And according to the development of the western center node city, Hubei province began to appear "With two pairs of spatial structure. The Hubei's economy as a whole has an important significance for the development of the network structure, to narrow the differences of eastern and western region, such as urban and rural differences plays an important role. Also it can reduce the center of Wuhan city polarization effect, producing a virtuous cycle to regional harmonious development. Formation and evolution of the network structure to the economy of Hubei province are effective summary. Research on the efficiency of economic network space structure of Hubei province made a foreshadowing.
