基于2005—2014年长三角26个市的统计数据,建立空间杜宾模型,运用matlab研究外部性,创意产业集群对城市创新的影响及空间溢出效应。实证结果表明金融与技术外部性不仅有效推动该市的创新,还存在较强的空间溢出效应,带动邻近城市的创新。创意产业集群对本市创新直接效应为正,对相邻城市创新间接效应为负。长三角各市之间存在较强的空间依赖性,城市创新互动明显,这为长三角地区合理利用外部性与创意产业集群大力提升城市创新水平提供政策依据。
Based on statistical data in 26 cities of Yangtze River Delta in 2005—2014, establish Spatial Dubin Model, use MATLAB to study the influence of externalities, creative industry cluster innovation and spatial spillover effect on the city innovation. Empirical results show that financial and technical externalities not only effectively promote the citys innovation, but also there is a strong spatial spillover effect, driven by the adjacent city innovation. The direct effect of creative industry cluster on this citys innovation is positive, and the indirect effect is negative. There is a strong spatial dependence among cities in Yangtze River Delta, and obvious innovation interaction, which provide a policy basis for the rational utilization of externalities and creative industrial clusters in Yangtze River Delta region to promote urban innovation level.
