【摘要】 随着经济全球化加速,城市间的要素流动性加快、空间结构扁平化,城市关系由层级范式向网络范式转变。文章考察城市网络主体间互动行为通过何种机制产生创新的外部效应,分析网络位置与地理距离的相互作用如何影响城市互动行为以及城市创新能力。通过构建城市网络均衡模型,分析网络中不同位置城市的均衡策略。借鉴城市联锁网络模型,选取高级生产性服务业(APS)数据构建关系型城市网络,发现中国城市形成网络层级性明显的子群。计量回归结果表明,与区域中心节点城市的连接越多,将有效提高城市创新能力。更多还原

【Abstract】 With the globalization of world economy,the structures between cities are becoming more and more flat.This paper examine how inter-strategy depends on the interaction of social and geographic distance,and indicates that cities that are more central in the social networks,or are located closer to the geographic center,choose high level strategies in the urban networks.APS data based on IWCNM are proposed to assess and differentiate the overall and local innovation performance for 102 Chinese cities.The results provide important implications and suggestions for those cities to enhance effectively the innovation performance.更多还原
