摘　　要：文章利用城市R&D支出数据、城市专利数据、城市统计年鉴数据等,采用永续盘存法、固定效应模型等方法,测算了中国2000—2019年14大城市群创新效率,并分析其演进及影响因素。研究发现:(1)中国创新效率呈上升趋势,但是不同城市群创新效率年均上升幅度差异显著;(2)城市群创新效率上升具有明显的阶段性;(3)不同城市群创新效率始终存在较大差距,且呈扩大趋势;(4)城市群内部R&D资本存量差异缩小以及物质资本存量积累是城市群创新效率上升的重要原因。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.
