Evaluation of industrial sustainable development of Yinchuan City based on footprint family

In order to actively respond to the construction of ecological protection and high-quality development pilot area in the Yellow River Basin and explore the development intensity and sustainable development status of various industrial resources in Yinchuan, the footprint of various industries in Yinchuan from 2011 to 2020 were quantified by using footprint family calculation method. The sustainable development status of industries in Yinchuan was evaluated by using the resource and environmental pressure index method and the Tapio decoupling model. Finally, the driving mechanism of each industry was analyzed by using the logarithmic mean Divisia index (LMDI) method. The results showed: 1) The water footprint of Yinchuan City showed a "V" -shaped change trend in the 10 years, and the lowest value reached 1.03×10⁶ hm² in 2016. The water footprint of Yinchuan City was mainly agricultural, accounting for more than 70%. The carbon footprint and ecological footprint showed a gradual upward trend, and the industrial carbon footprint and ecological footprint were dominant, accounting for about 95% and 85%, respectively. 2) The overall water resource pressure index showed a "V" -shaped change trend, with a difference of about 3 times between the maximum and minimum values. The carbon emission pressure index showed an inverted "L" -shaped change trend, and the pressure index reached the maximum value of 220 in 2019, while the ecological pressure index showed a "wave" -shaped upward trend. The pressure index was close to 220 in 2020, indicating that the pressure of resources and environment was gradually rising. 3) The overall performance of agricultural sustainable development evaluation was "good", the overall performance of industry was "poor", and the living and ecological industries showed a "good - poor" trend. 4) The factors of environmental carrying capacity and footprint production efficiency of each industry promoted industrial development, while water resources consumption, carbon emission, and environmental pollution degree mainly inhibited the agricultury, industry, and living and ecological industry, respectively. The research shows that the agricultural footprint of Yinchuan City has a small change range and rapid economic development, with a good trend toward sustainable development. The pressure on industrial resources and environment is rising sharply and the economy is rising slowly, which is not conducive to sustainable development. The rising rate of resources and environment pressure on living and ecological industry is greater than the rate of economic development, and the ability of sustainable development is gradually declining.
