Evaluation of provincial green development performance based on DPSIR model

Improving the level of green development is an important way to promote the construction of ecological civilization and realize beautiful China. The driving force-pressure-state-impact-response (DPSIR) model was used in the evaluation of green development performance to build a provincial green development performance evaluation index system under the vision of building a beautiful China. The analytic hierarchy process was used to calculate the index weights, and the objective asymptotic method was used for data standardization. On this basis, the provincial green development performance comprehensive index was constructed. The green development level from 2009 to 2019 of Guizhou Province was evaluated. The results showed that the green development performance comprehensive index of Guizhou Province from 2009 to 2019 had been increasing yearly, with the trend from Level Ⅰ (low) to Level Ⅲ (general). The indexes of social pressure, resource consumption, and pollutant emissions of the pressure layer had the greatest impact on the green development of Guizhou Province in the DPSIR model. At present, the green development of Guizhou Province was at a general level (Level Ⅲ). Improving the level of economic development, implementing ecological environment remediation, promoting pollution reduction and carbon reduction, and increasing people′s livelihood security should be paid more attention to improve the level of green development in Guizhou Province, and ultimately complete the construction of the Beautiful Guizhou.
