Abstract：Based on the goal of"double carbon"in the new era,the spatial-temporal evolution of energy eco-efficiency in the Yellow River Basin was studied.This research constructed a non-radial directional distance function taking into account the impact of clean energy,estimated the energy eco-efficiency of 8 provinces and 55 prefecture-level cities in the Yellow River Basin combining with the SBM super-efficiency model of non-expected output,analyzed the path of energy-saving and emission-reduction.The results find that:the energy eco-efficiency of the Yellow River Basin shows a multi-stage time-series change during the study period;the spatial agglomeration phenomenon in the watershed is significant,and the low-low agglomeration is the largest,distributing in the upper reaches,followed by low-high agglomeration and high-high agglomeration,distributing in the middle reaches and downstream Shandong Province.Based on this,the energy-saving and emission-reduction potential of the Yellow River Basin is calculated to put forward targeted suggestions,and the 55 prefecture-level cities are divided into A,B,and C areas by using a two-dimensional matrix map.Among them,the C area performs the best,and the A and B areas could adopt a bilateral or unilateral energy-saving and emission-reduction path to transition to C area.
