Based on the data of urban R&D expenditure,urban patent and urban statistical yearbook,and using the methods of perpetual inventory and fixed effect model,this paper measures the innovation efficiency of 14 major urban agglomerations in China from 2000 to 2019,and analyzes their evolution and influencing factors.The results show that:1)The innovation efficiency of China is on the rise,but the average annual increase of innovation efficiency of different urban agglomerations is significantly different.2)The rise of innovation efficiency of urban agglomerations has obvious stages.3)It has a large gap between the innovation efficiency of different urban agglomerations and show the expansion trend.4)The narrowing of the difference of R&D capital stock within urban agglomerations and the accumulation of physical capital stock are the important reasons for the rise of innovation efficiency of urban agglomerations.
