Abstract
Green development is an important way to achieve sustainable development. In recent years, it has become one of the main research hotspots. Based on the principle of the DPSIR model, this paper constructed a green development evaluation index system including 17 second-level indicators from five first-level indicators, namely the driving force indicator, pressure indicator, state indicator, impact indicator, and response indicator, and used TOPSIS model to evaluate the green development of Beijing-Tianjin-Hebei region from 2010 to 2020. The results show that :(1) the closeness index of the driving force and pressure indicator layer generally shows a fluctuating trend of first rising and then falling, the closeness index of the state layer shows a fluctuating downward trend, the influence indicator layer shows an overall upward trend, and the closeness index of the response indicator layer shows a trend of first declining and then rising. (2) Due to the existence of regional heterogeneity, the green development of Beijing is higher than that of Tianjin, and the green development of Tianjin is slightly higher than that of Hebei. The Beijing-Tianjin-Hebei region needs to form cohesion in green development governance. (3) It is found that the economic growth rate of the Beijing-Tianjin-Hebei region is very fast, but in terms of green development, there is still an extensive development trend with high input and high consumption.
