摘　　要：城市间经济联系的定量分析能揭示区域协调发展的状态.运用修正后的引力模型分别计算出徐州各县市区在2000,2005,2010年的城市经济联系值,并采用整体网络分析软件UCINET,对徐州市各县市区之间的经济联系的网络结构进行了进一步的测度.结果表明:徐州区域经济空间结构网络密度较低,但密度值增加较快,区域间经济联系渠道越来越多;经济发展模式为核心区域带动模式,主要的经济联系集中在市区与铜山县、邳州市等一些经济较发达的地区,各县市区之间的经济联系不对称性结构明显.The condition of economic coordination in the region is revealed by the quantitative analysis of economic relations between cities. The economic relation values of 2000, 2005 and 2010 in Xuzhou are respectively calculated through the modified gravity model, and the network structure of economic relation of Xuzhou is analyzed by social network analysis model. The results show that the network density on spatial structure of regional economic is low, but the network density is increased rapidly, and the linkages of regional economic are strengthened. The economic development presents the model of core region driven. The major economic linkages arc mainly concentrated on some economically developed districts, for instance, urban district, Tongshan County and Pizhou County. Structural a- symmetry of economic linkage between downtown and counties is significant.
