Abstract The paper obtains a point to reflect regional innovation of Yangtze River Delta by structuring regional innovation capability assessment system.It analyzes and discusses the regional innovation spatial linkage of Yangtze River Delta deeply by using gravity model,and determines the central city of regional innovation spatial linkage on the basis of the number of the largest attraction linkages and gross of regional innovation spatial linkage.It also combines with“Breaking Point”formula to measure and calculate the radiation range of the central city.The result shows:regional innovation spatial linkage of Yangtze River Delta is unbalanced,the number of regional innovation spatial linkage of cities in south of Jiangsu and north of Zhejiang and Shanghai is large,but cities in north of Jiangsu and in south of Zhejiang relatively low;regional innovation spatial linkage of Yangtze River Delta coincides with the main metropolis circle of Yangtze River Delta;Hangzhou and Suzhou become the core cities of regional innovation spatial linkage of Yangtze River Delta in 2011,the radiation range of regional innovation in Hangzhou is tend to north,and it tends to around in Suzhou.
