Energy efficiency and its influencing factors of resource-based cities in the Yellow River Basin under the constraint of environment

Improving the energy efficiency of resource-based cities in the Yellow River Basin and ensuring energy security are the key ways to accelerate the realization of ecological protection and high-quality development in the Yellow River Basin.In the study of 36 resource-based cities in the Yellow River Basin, establishing the energy efficiency evaluation index system for resource-based cities in the Yellow River Basin, based on the statistics of energy efficiency input-output indicators from 2017 to 2019, the C²R model and SBM model are used to compare the energy efficiency values considering environmental pollution output and excluding environmental pollution output, the Tobit model is used to analyze the influencing factors of energy efficiency in resource-based cities under environmental constraints in terms of economic development level, industrial structure, import and export, foreign direct investment, government influence and resource development degree.The results show that except for Qingyang City, Ordos City, Luoyang City, Puyang City, Sanmenxia City, Dongying City, Baoji City, Xianyang City and Yulin City, the energy efficiency of most resource-based cities in the Yellow River Basin is in an ineffective state; according to the different classification criteria, Growth-type, oil and gas type, and downstream region resource-based cities have the highest energy efficiency level; the level of economic development has a significant positive impact on the energy efficiency of all resource-based cities and downstream regions, it has a significant negative impact on resource-based cities in upstream regions; industrial structure has a significant positive impact on energy efficiency in upstream regions, it has a significant negative impact on the energy efficiency of resource-based cities in the downstream regions; foreign direct investment has a significant positive impact on the energy efficiency of resource-based cities in the upstream and downstream regions; government influence has a significant positive impact on the energy efficiency of all resource-based cities; the development degree has a significant positive impact on the energy efficiency of resource-based cities in all cities and upstream regions.In view of this, it is suggest that local cities should seek development models suitable for their own characteristics, pay attention to the coordinated development of economic development and environmental protection, promote the adjustment of industrial structure, increase foreign direct investment, enhance the influence of the government and accelerate technological innovation.This paper provides a reference for improving the development and utilization of resources in resource-based cities.
