Digital Technology Innovation,Energy-Biased Technological Progress and Total Factor Energy Efficiency
Digital technology innovation(DTI)affects energy-biased technological progress(EBTP)by changing the al-location of capital and energy factors,and EBTP further impacts total factor energy efficiency(TFEE).Based on the da-ta of 275 cities at the prefecture level and above in China from 2006 to 2021,the two-way fixed effects model is used to empirically test the impact of DTI on EBTP and EBTP on TFEE.The findings are as follows:During the sample period,the level of DTI of Chinese cities shows an increasing trend;China's urban technological progress is mainly biased to-wards capital,but the degree of capital bias is weakening,and there is an overall substitution relationship between energy and capital.DTI can promote EBTP.DTI can promote EBTP by increasing the absolute scale and relative scale of energy consumption.The impact of DTI on EBTP is significant in the central and western regions,but it is not significant in the eastern and northeastern regions.Besides digital products and services,other dimensions of DTI can significantly promote EBTP.Through extended analysis,we found that EBTP harms TFEE when there is a substitution relationship between energy and capital.
