With resource consumption and ecological deterioration, improving the efficiency of green innovation is seen as an important way to promote regional ecological civilization construction and promote high-quality economic development. Based on the SBM-undesirable model, the green innovation efficiency of 110 prefecture-level cities in the Yangtze River Economic Belt from 2012 to 2016 was measured. The coefficient of variation and ESDA were used to reveal the temporal and spatial evolution of the time and space. The results show that: ①From the evolution of time, the average value of green innovation efficiency of the upstream, midstream and downstream area of the Yangtze River Economic Belt is increasing gradually and the imbalance between regions is first improved and then aggravated; ②In terms of spatial evolution, urban green innovation efficiency The spatial polarization effect is gradually expanding; the global Moran's I shows a significant positive spatial correlation. Finally, it puts forward some measures such as aiming at the regional function, breaking the administrative barriers of regional green innovation spillovers, etc.
