Evaluation of Ecological Welfare Performance and Influencing Factors in the Gansu Section of the Yellow River Basin
The paper is based on the super-efficient SBM model and panel Tobit model, it measures the ecologi-cal welfare performance of Gansu section of the Yellow River Basin and analyzes its influencing factors. The results show that the ecological welfare performance of the Gansu section of the Yellow River Basin is increasing year by year from 2010 to 2020, and the inter-regional differences become bigger.In addition to Tianshui City, the total fac-tor productivity(TFP)level exceeds 1, and fluctuates in the shape of M with time. Among them, the low technologi-cal efficiency constrains the improvement of TFP in Tianshui City.The population density,urbanisation level and av-erage annual temperature are the main factors affecting the improvement of ecological welfare performance in the re-gion,among them,urbanisation level and average annual temperature play a positive role,while population density plays a negative role,other factors such as precipitation, education expenditure and highway mileage have no signifi-cant influence.
