鄱阳湖生态经济区城市间经济联系社会网络分析研究
Research on the Cities’Economic Contacts of Poyang Lake Ecological Economic Zone Based on the Social Network Analysis

应用修正的引力模型测算鄱阳湖生态经济区城市间经济联系，采用社会网络分析方法对城市间经济联系进行分析。研究结果显示：鄱阳湖生态经济区城市间网络密度值较小，城市间经济联系相对较弱；中心度分析显示南昌市区是该区域的“中介”城市；凝聚子群分析进一步说明了南昌市区在区域中的地位和作用，同时整个区域网络结构具有较多的小团体分布。在今后应采取一些措施加快区域一体化进程。
The modified gravity model is applied to measure the cities’economic contacts of Poyang Lake Ecological Economic Zone,and the urban agglomerations’economic contacts are analyzed by the network. The result shows that the network density of Poyang Lake Ecological Economic Zone is low,and the economic contact of urban ag-glomeration is relatively weak. The centrality degree shows Nanchang is intermediary of the region. The cliques anal-ysis further confirms the position and role of Nanchang in the region,and the whole area network structure with man-y small groups of distribution,it is not conducive to the overall development of the region. In the future the regional should adopt some measures to accelerate the process of regional integration
