Abstract: Taking the 27 cities of the Yangtze River Delta urban agglomeration from 2010 to 2019 as the objects, this paper discusses the innovation capability, the evolution features of innovation linkage network, the central innovative cities- radiation range in the Yangtze River Delta urban agglomeration by using global principal component analysis, gravity model, faultpoint formula etc. The results show that: (1) The innovation capability of the Yangtze River Delta urban agglomeration features gradient diffusion; (2) The total amount of innovation linkage in the agglomeration has shown an upward trend, and its pattern has obvious “core” and “peripheral” areas; (3) There are differences in the evolution of the innovation linkage network structure of the Yangtze River Delta urban agglomeration: the number of edges of innovation linkage in each city has increased significantly, and the number of linkage between eastern cities and western cities has also increased significantly; (4) The number of central innovative cities has increased from 2 in 2010 to 3 in 2019, and the radiation scope has been significantly expanded.
