Measurement of Eco-Efficiency and Analysis of Influencing Factors in Dabie Mountain Counties
Based on the panel data of 63 counties(urban areas)in the Dabie mountainous region from 2015 to 2020,this article measures the county eco-efficiency by using the super-efficiency SBM model,analyzes the trend of eco-efficiency changes at the provincial and county levels,and constructs the Tobit regression model to analyze the influencing factors of the eco-efficiency of the counties in the Dabie mountainous region at the overall and provincial levels.The results show that:as a whole,the eco-efficiency of Dabie mountainous area generally shows an upward trend between 2015 and 2020,and the eco-efficiency of each province is ranked from high to low as follows:Anhui Province>Henan Province>Hubei Province.From the county level,the eco-efficiency of most of the counties(districts)in Dabie mountainous area has increased during the study period,and the eco-efficiency values of a few counties(districts)have declined,The eco-efficiency of the Dabie mountainous area has increased during the study period.Among the factors influencing ecological efficiency,environmental regulation,location conditions,economic level,industrial structure and government intervention play a positive role.
