Investigation on the complex relationship between urbanization and eco-efficiency in urban agglomeration of China: The case study of Chengdu-Chongqing urban agglomeration
“…Secondly, by considering ecological welfare performance comprehensively, we aim to enhance cities’ resilience to environmental challenges, thereby promoting sustainable development 62 – 64 . Lastly, integrating ecological welfare performance with new urbanization enables a more holistic assessment of urban development quality, ultimately enhancing residents' quality of life 65 , 66 .…”
New urbanization (NU) and ecological welfare performance (EWP) play pivotal roles in achieving sustainable urban development, with both emphasizing social equity and environmental management. Exploring the coordinated relationship between EWP and NU is invaluable for understanding the symbiotic interplay between humans and nature. We constructed a framework to elucidate the coupling mechanism of EWP and NU from the perspective of systems theory. We quantified the levels of NU and EWP utilizing the entropy weighting method and the super-efficient SBM method, respectively. Furthermore, we assessed the degree of coupling coordination between the two using the coupling coordination degree model (CCDM). Spatial and temporal evolution analysis was conducted, and factors influencing the degree of coupling coordination between EWP and NU were explored through a spatial–temporal geographically-weighted regression model (GTWR). The results indicate: (1) During the study period, the average annual increase in EWP in the study area was 2.59%, with a narrowing relative gap between cities. Conversely, the average annual increase in the level of NU was 7.6%, with demographic and economic dimensions carrying the highest weights. (2) The type of coupling coordination between EWP and NU transitions from basic coordination to moderate coordination, with the development of EWP lagging behind that of NU. (3) City size demonstrates a positive yet diminishing trend on the coupling coordination level, with economic development exerting the greatest influence and exhibiting a "V" trend, while the impact of green technology innovation diminishes negatively. Additionally, regional disparities are significant, with city size exhibiting a negative impact in areas of high population density and low economic levels, and green technology innovation showing notable polarization characteristics in core cities. These findings serve as a foundation for fostering coordinated ecological development amid the rapid urbanization process of the Chengdu–Chongqing Economic Circle.

“…However, subject to the influence of natural conditions, there are frequent encroachment for arable land or forest land around the CCEC, and the conflict of land use is exceptionally intense. At the same time, the CCEC has witnessed a gradual increase in the urban-rural income gap within regions and a wide gap in the urban-rural development level between regions in recent years [ 23 , 24 ].
