Randomized trial assesses urbanization impact on eco-environmental quality in China, indicating significant spatial differences.

This study aims to quantify how urbanization interacts with eco-environmental quality in five major Chinese urban areas.
Analyzed urbanization and eco-environmental quality from 2001 to 2024 using remote sensing data.
Developed an eco-environmental index (AMEI) and urbanization index (MCNLI).
Utilized a dual peri-telecoupling-inspired coordination model to examine spatial interactions.
Average urbanization level rose from 0.24 to 0.33 (38.9%), while eco-environmental quality declined from 0.44 to 0.39 (11.3%).
Pearl River Delta showed an increase in eco-environmental quality by 18.7%.
Coupling coordination degree improved from 0.55 to 0.65 (19.3%), with notable regional variation.

Fu et al. (2026) studied this question.
