Measurement and influence factors of ecological efficiency of the Yangtze River economic belt under high quality development conditions
China Environmental Science,2020,Vol 40,No. 02
The four-stage analysis framework of NSUSBM-SFA-NSUSBM-Tobit was constructed in this paper. Based on the panel data of 107 cities in the Yangtze River economic belt from 2007 to 2016, the global DEA technology was used to calculate the eco-efficiency of cities under the inseparable assumption. Then the three-stage DEA model was used to introduce natural factors. And combined with the new development concept, The Tobit model was used to analyze the influencing factors of urban eco-efficiency. Regardless of the environmental differences in the cities, the average comprehensive ecological efficiency in the Yangtze River economic zone increased from 0.288 to 0.617 in 2007–2016, with an increase by 114.24%. It has crossed the low-quality development stage of 0.4, but was still lower than the high-quality development standard of 0.8 in 2016. The ecological efficiency of Hunan Province grew fastest, with an increase by 213.85%. Considering the environmental differences, the average comprehensive ecological efficiency of the Yangtze River economic zone increased from 0.150 to 0.395 in 2007–2016, with an increase by 163.33%. Shanghai grew fastest, with an increase by 311.52%. Shanghai, Jiangsu and Zhejiang ranked the top three in most years, while Jiangxi, Guizhou and Yunnan ranked the bottom three. Innovation, urban-rural coordination, government environmental investment, foreign investment and urbanization all contributed to eco-efficiency.
