Urban environmental governance efficiency in the Yangtze River region shows significant disparities and a sharp decline over the past decade. Technological progress, driven by scale efficiency, is key to improving this environmental governance.
Area of Science:
- Environmental Science
- Urban Planning
- Economics
Background:
- Developing countries face challenges balancing economic growth with environmental protection.
- Urban environmental governance is critical for sustainable development.
Purpose of the Study:
- To analyze temporal and spatial efficiency of urban environmental governance.
- To identify factors influencing urban environmental governance efficiency.
Main Methods:
- Data Envelopment Analysis (DEA) model for efficiency measurement.
- Tobit model for analyzing influencing factors.
- Deconstruction of efficiency into comprehensive, pure technical, and scale efficiency.
Main Results:
- Significant disparities in environmental governance efficiency across cities (0.934 vs. 0.246).
- A sharp decline in comprehensive efficiency from 0.708 to 0.493 over 10 years.
- Technological progress, driven by scale efficiency, is the primary driver; industrial structure and population density are favorable factors.
Conclusions:
- Urban environmental governance efficiency requires targeted strategies to address disparities.
- Technological advancements and scale efficiency are crucial for improvement.
- Economic level and urban construction negatively impact efficiency, while industrial structure and population density positively influence it.
