摘　　要：按照空间计量经济学要求选择地理质心并引入地理距离,以2003-2007年中国三大"城市群"面板数据为样本,实证分析空间知识溢出影响因素的作用机制。研究发现,空间知识溢出的影响因素,不仅包括地理距离、知识缺口,同时还受中心城市人口相对拥挤程度、周边地区吸收能力差异等因素的影响。知识缺口明显阻尼了空间知识溢出的发生,而中心城市发展空间缺口显著加速了知识的外溢。在控制吸收能力影响后,空间知识溢出的地理衰减过程不再显著。Based on the data of three＂city group＂ in China from 2003-2007,following with geography distances were introduced according to the methods of spatial geography economics,the mechanisms of influential factors of spatial knowledge spill-off were analyzed empirically.The research results indicated that the influential effects of spatial knowledge spill-off may be complicated,which not only included geography distances,knowledge gap but also included spatial gap and absorptive capability.Knowledge gap hampered spatial knowledge spill-off significantly,while,spatial gap accelerated spatial knowledge spill-off significantly.When the absorptive capability was controlled,the effects of geography distances became insignificant.
