The purpose of this paper is to investigate and evaluate the spatial distribution of urban innovation in the Yangtze River Delta. In this study, the data of innovation ability of 16 cities in the Yangtze River Delta region from 2001 to 2012 were selected. Based on the coefficient of variation, Gini coefficient, Herfindahl-Hirschman index, spatial autocorrelation and spatial regression analysis method, combined with GIS spatial analysis, SPSS data analysis tools and Geoda software, this paper examines the spatiotemporal change and influencing factors of innovation capability in the Yangtze River Delta cities. The main conclusions are as follows: (1) The overall spatial differentiation and innovation concentrations of the region have been stable in recent years. (2) The spatial pattern of innovation is still in dynamic change, but a high innovation output zone which consist of Shanghai, Suzhou, Wuxi, Changzhou and Nanjing has formed. The innovation space in the delta has shown fluctuating characteristics, with a minor positive spatial correlation among cities. This indicates that a certain degree of spatial heterogeneity exists in the Yangtze River Delta region. (3) Urban innovation has shown a certain degree of spatial spillover effect. The level of investment, environment and scale of the innovation are the main factors influencing the spatial differentiation of innovation capacity of cities in the region. The research results provide some guidance for the improvement of city innovation capacity and regional sustainable development of the Yangtze River Delta.
