Digital Technology Application and Energy Efficiency Improvement:Empirical Evidence from China's Urban Level
Energy efficiency is the key to the implementation of dual carbon goal,and digital technology application provides an important impetus for energy efficiency improvement.This paper theoretically analyzes the impact of digital technology application on energy efficiency,and constructs a digital technology application index based on the panel data of 271 cities in China from 2011 to 2020,and empirically tests the dynamic correlation and mechanism.The results show that digital technology applicationcan significantly improve energy efficiency,and has positive effect on energy efficiency of surrounding areas.The mechanism analysis shows that the improvement effect of digital technology application on energy efficiency is mainly due to the upgrading of industrial structure and technological innovation mechanism.Further analysis shows that the improvement effect of digital technology application on energy efficiency has typical heterogeneous characteristics and dynamic changes in spatio-temporal dimension.Based on the above findings,this paper puts forward corresponding policy suggestions from the aspects of building digital ecology,providing institutional guarantee and adopting digital technology development strategy according to local conditions.
