摘　　要：以长三角城市群26个城市为观测对象,运用泰尔(Theil)指数二阶分解方法、探索性空间数据分析方法以及地理探测器法,从时间和空间视角分析2005—2014年长三角城市群创新产出差异的时空格局演变及其影响因素。研究表明:(1)城市群创新产出的相对差异有减少的趋势,且区域内部异质性作用明显;(2)城市群创新产出在空间上存在不均衡的集聚分布,总体呈现出"北冷南热,西冷东热"的空间关联特征;(3)随着时间的推移,信息化水平逐渐成为影响长三角创新产出差异的主导因素。Taking 26 cities in the Yangtze River Delta urban agglomeration as the observation object, the second order decomposition method of Theil coefficient, the exploratory spatial data analysis method and the geographical detector method are used,from the perspective of time and space, this paper analyzes the evolution of spatial and temporal patterns of innovation output differences in Yangtze River Delta urban agglomeration from 2005 to 2014 and its influencing factors. The results show that：（1） the relative difference of innovation output of urban agglomeration has a decreasing trend, and the effect of regional heterogeneity is obvious;（2） there is an unbalanced agglomeration distribution of innovation output in urban agglomeration;（3） with the passage of time, the level of informatization gradually becomes the dominant factor that affects the difference of innovation output in the Yangtze River Delta.
