Abstract In order to solve the problem of regional innovation imbalance caused by uneven distribution of innovation power field of regional central cities and realize regional collaborative innovation, an empirical study on the radiation effect of innovation ecosystem of regional central cities in Yangtze River Delta urban agglomeration was conducted based on the fracture point model, innovation force field model and innovation radiation force model. The results show that the innovation power field of the Yangtze River Delta urban agglomeration is distributed in a circular network with the boundary of "Shanghai Suzhou Nanjing Hefei Hangzhou Shanghai", including five core radiation areas: Shanghai innovation radiation zone, Suzhou innovation radiation zone, Hangzhou innovation radiation zone, Nanjing innovation radiation zone and Hefei innovation radiation zone; The distribution of innovation power field is uneven, and the innovation field near the core radiation area is dense, and it is affected by multiple radiation effects, while the radiation effect of marginal city is weak; The amount of innovation elements brought by the surrounding cities has a multiplier effect on the innovation field, and the radiation effect of innovation can be amplified by increasing the amount of innovation elements.
