中文摘要：

作为全球化运输网络的重要节点,空港具有汇聚资本和人才等研发资源的强大能力,同时航空运输也有助于知识精英远距离旅行和跨区域交流,从而能促进知识和技术的空间扩散,因此空港通常成为城市创新的推动者.选取我国29个主要空港2006～ 2010年客流量的相关数据,用一步系统广义矩估计法,实证检验了空港对城市创新能力提升的重要作用.研究结果表明,航空客流每增加1个百分点,该城市研发产出将增加0.22个百分点.

英文摘要：

As an important node of the global transportation network, Airport has the powerful capability to make the R＆D resources, such as physical capital and human resources, converge in the city. Meanwhile, Air service makes the long - distance travel and inter - regional communication of educational elites more con- venient. So the airport can be the catalyst to urban innovation by means of the knowledge and technology spill- overs. Based on the panel data of 29 metropolitan cities in China from 2006 to 2010, the paper has provided an empirical analysis on the relevance between airport and urban innovation using the one - step GMM specifi- cation. The result is that the elasticity of patent OUtlauts to airoort passengers is O. 22.
