The Impact of Resource Endowment and Digital Transformation on the Efficiency of Energy Transition

open access: yesEnergy Science &Engineering, EarlyView.
Resource endowment has a significant positive direct effect and a stronger spatial spillover effect on ETE, while digital transformation can improve local efficiency but has some negative spillover effects on neighboring regions. ABSTRACT In contemporary society, improving energy transition efficiency (ETE) has become a necessary measure to ensure the ...
