Analysis of Green Total Factor Productivity in China′s Power Industry
To promote the sustainable development of the electricity industry in China,the Data Envelopment Analysis(DEA)method was used to measure the green total factor productivity(GTFP)of the electricity industry in 30 provinces,municipalities,and autonomous regions in China from 2016 to 2020 and its practical and spatial varia-tion characteristics were analyzed.The results indicate that from 2016 to 2020,the GTFP in the electricity industry of 30 provinces,municipalities and autonomous regions(except Tibet)in China is 1.000 7,the average green techno-logical progress is 1.000 2,and the average green technical efficiency is 1.005 1.Compared with economic develop-ment factors,green development factors such as environmental governance and scientific and technological invest-ment have a more significant impact on green total factor productivity,green technological efficiency,and green technological progress.From the perspective of time characteristics,GTFP shows a fluctuating trend,and from the perspective of space characteristics,it shows the characteristics of regional imbalances.Therefore,it is further pro-posed to focus on technological progress,optimize the input-output ratio of the electricity industry through the appli-cation of carbon reduction technologies and equipment,enhance the stability of the electricity industry′s operations,and reduce the volatility of GTFP and other suggestions.
