Study on the evaluation and improvement strategy of the ecological environment governance capacity of the Yangtze River Economic Belt

In order to strengthen the improvement and optimization of eco-environment management in the Yangtze River Economic Belt, the paper studies the use of KPCA to build a judgment model of eco-environment management capacity, and analyzes the factors affecting the governance capacity in combination with the panel data regression model, so as to propose strategies for improving the governance capacity. The research outcomes indicate that from 2012 to 2021, the environmental and ecological governance capacity of the Yangtze River Economic Belt maintained an upward trend, and the governance capacity of the lower reaches was the best, with Shanghai, Jiangsu and Zhejiang ranking the top three, and Yunnan and Guizhou ranking the worst. The regression coefficients of industrial development, urbanization, economic development and opening to the outside world are − 3.4896, − 3.7891, 2.3489 and 0.1148 respectively. It is required to strengthen environmental and ecological governance from four aspects of industrial transformation, urban construction, green economy and open communication, and improve the eco-environment management capacity and level of the Yangtze River Economic Belt.
