Spatial effect and mechanism of technological innovation on energy use efficiency:Panel data from 278 cities at or above the prefecture level in China
Based on the spatial perspective,using the panel data of 278 prefecture-level cities in China from 2008 to 2019,and adopting the spatial Durbin model and panel threshold model,the article empirically tests the direct,indirect and threshold effects of technological innovation on energy efficiency.The research shows that technological innovation is not only conducive to improving the energy use efficiency of the local city,but also improves the energy use efficiency of neighboring cities through spillover effect with spatial spillover effect.It also finds that there exists significant spatial spillover effect,and that the impact of technological innovation on energy use efficiency is heterogeneous due to different urban locations and technological innovation levels.Green technology progress and industrial structure upgrading play an intermediary role in technological innovation to improve energy use efficiency,and technological innovation improves energy use efficiency by improving green technology progress and promoting industrial structure upgrading.When the level of economic development is low,technological innovation has an obvious inhibitory effect on energy utilization efficiency.When the level of economic development exceeds a certain critical value,technological innovation can significantly improve energy utilization efficiency.
