摘　　要：在经济联系网络模型基础上,将社会网络分析法与核密度估计法结合,实证分析长江经济带的经济联系网络结构、中心节点、网络密度及网络子群特征并提出相应的对策建议。结果显示:长江经济带整体经济联系网络密度处于较低水平;经济联系网络密度呈自下游向上游逐渐减弱的梯度发展态势;经济带包括4个区域性子群,小团体特征显著,子群间的互动较弱。因此,本文提出要充分发挥各区域比较优势,提升区域的整体竞争力,加快长江经济带经济一体化进程的总体优化方向,并针对各区域提出区域性的优化建议。In the new era, research on economic relationship of Yangtze River Economic support belt especially the urban economic relation network has important strategic significance for city development along the Yangtze River. This paper combined the method of social network analysis and kernel density estimation based on economic relation network model, analyzed the network structure, center node, network density and contact characteristics of the network subgroup of the whole economic relation network and moreover put forward the corresponding optimization direction. The results indicated that the economic relation network is still at lower levels and the network contact has not been formed yet; The economic relation appears a trend of gradual decline while each part has its own density characteristics; The whole network contains 4 regional subgroups, the internal relation in each subgroup is relatively significant, while the external relation between different subgroups is relatively weak. Based on this reason, this paper proposed that each region should develop its relative advantages in improving regional competitiveness, to speed up economic integration of Yangtze River Economic Zone and put forward the optimization strategy.
