Abstract：Based on panel data from 273 prefecture-level cities spanning the years 2006 to 2020,this study constructs a spatial Durbin model to investigate the impact of regional innovation levels on energy utilization efficiency.Empirical results show that,compared to linear models,the spatial Durbin model has a better explanatory performance.The direct effect of regional innovation levels on energy utilization efficiency exhibits a"U-shaped"trend,initially decreasing energy utilization efficiency as regional innovation levels rise,crossing a turning point,and then increasing energy utilization efficiency.The indirect effect follows the opposite trend,with most regions currently positioned to the left of the"U-shaped"curve.Analyses from the dynamic spatial panel model and a one-period lag of regional innovation levels demonstrate the robustness of the regression results.Additionally,there are significant regional differences in the impact of regional innovation levels on energy utilization efficiency in the eastern,central,and western regions.Recommendations include advancing energy technology innovation to propel innovation levels beyond development turning points,gradually strengthening regional cooperation to foster positive spillover effects,and formulating differentiated regional development strategies that focus on regional disparities and mutual coordination.
