福建省能源效率的时空分异及影响因素研究OA北大核心CSTPCD

Using the super-efficiency SBM model,this study calculates the comprehensive en-ergy efficiency of prefecture-level cities in Fujian Province from 2011 to 2021,analyzing their spa-tio-temporal differentiation characteristics and influencing factors.The results show that,overall,the comprehensive energy efficiency of Fujian Province is at a relatively high level and shows a steady growth trend.However,the overall disparity in energy efficiency levels across Fujian Prov-ince has rapidly expanded since 2019.Economic development level and the degree of openness to the outside world are important positive influencing factors for the improvement of comprehensive en-ergy efficiency in Fujian Province,while industrial structure,proportion of production factors,technological level,and government intervention are negative influencing factors.
