Abstract: Eco-efficiency is an effective measurement of sustainable development. Studies on the industrial ecological efficiency of Xinjiang,an ecological fragile arid region in China,are of important practical significance to promote the coordinated development of industry and ecological environment and achieve the goal of ecological civilization construction. In this study,the industrial panel data of Xinjiang from 2001 to 2015 were taken as the samples,the super efficiency DEA model was used to evaluate the ecological efficiency and its changes in 14 prefectures,autonomous prefectures and cities in Xinjiang Uygur Autonomous Region,and the Tobit regression model was used to analyze the factors affecting the industrial ecological efficiency. The results showed that: ① The overall level of industrial ecological efficiency in Xinjiang was not high,but the development trend was good. The industrial ecological efficiency was increased in a fluctuation way,and its comparative growth was 109.8%. It was increased from 0.75 during the Tenth Five-year Plan period to 1.0 during the Eleventh Five-year Plan period and further to 1.08 during the Twelfth Five-year Plan period; ② The industrial eco-efficiency in Xinjiang was imbalance,the highest and lowest values were 8.97 and 0.59,respectively,and their difference was 15.2 times; ③ The industrial eco-efficiency was positively correlated with the industrial development level,scientific and technological innovation,industrial structure and environmental planning,but negatively correlated with opening to the outside world and industrial agglomeration.

Key words: industrial eco-efficiency, super efficiency DEA model, Tobit regression, Xinjiang
